What is new

Every release and what it changed for you. The number in the footer of every page is the release you are looking at.

    1. Account and billing safetyv0.39.9

      • One free trial per inbox: a new account on the same email address, or a +tag version of it, checks out without a second trial.
      • If someone signs up with your email address before you do, opening the confirmation email in your own browser clears their password, and you choose yours.
      • A refunded or disputed day pass ends at once; a refunded or disputed subscription is cancelled.
      • Sign-in, sign-up and password-reset limits are now shared across all of ArbWins's servers.

    2. Account deletion fixv0.39.8

      • An account that opened checkout but never paid can be deleted again; only a plan that can still bill blocks deletion.

    3. Security hardeningv0.39.7

      • A plan's access now follows its paid period as well as its status, and plans are re-checked against Stripe hourly, so a missed cancellation can't leave access open.
      • Live boards close and re-check your plan when a day pass or plan ends, and at least every six hours.
      • An account with a plan that can still bill can't be deleted until the plan is cancelled, so nobody is charged for an account that no longer exists.
      • Sign-in limits now count each visitor separately behind Cloudflare, sign-in links can only send you to pages on ArbWins, and billing fields can't be set from outside.
      • Sharing prices from the browser extension now needs Pro or a day pass, and shared labels can only name a player and a stat.
      • Next.js updated to 16.4.1 for the October security fixes.

    4. More of theScore Betv0.39.6

      • theScore Bet's milestone ladders ("30+ receiving yards", "25+ points") are read as Over lines, so they pair with every other book's Unders: about 1,700 new rungs across NBA and NFL games.
      • theScore Bet's NHL goalscorer props and its alternate spreads and totals for NFL, NBA and NHL games are read too.

    5. Search and polish fixesv0.39.5

      • The middles board loads in about a second instead of thirteen.
      • Search engines now get each game page's title and description up front, made-up odds addresses answer "not found" properly, and games only one book prices stay out of search until a second book posts them.
      • The bonus-bet board never leads with a pair that converts above 100%: that is an arbitrage or a stale price, and it is marked as one.
      • Kalshi has its own logo, error pages say what to do next, and a few book counts and claims were corrected.

    6. Edges stay put through an updatev0.39.4

      • Edges are now kept through the first five minutes after an update, the time it takes every game's props and alternate lines to be read again (two and a half minutes was not enough).

    7. No repeat alerts after an updatev0.39.3

      • An edge that leaves the board and comes back within 15 minutes no longer sends its alert again.
      • Right after an update, props and alternate-line edges stay on the board while their prices are re-read, instead of disappearing for about two minutes.

    8. The ArbWins icon in search resultsv0.39.2

      • The site now serves a favicon.ico and a 96-pixel icon, the sizes Google Search uses, so results can show the ArbWins mark instead of a blank globe.

    9. DraftKings checked twice toov0.39.1

      • DraftKings prices are now read from its league snapshot and from each game's own page, and compared. In the first live check, all 144 prices compared agreed.

    10. Every price checked twicev0.39.0

      • ArbWins now reads FanDuel, BetRivers and Desert Diamond prices from two places: each book's league page and each game's own page. Where both read a price, the leg says "2 reads agree". In the first live check all 300 prices compared agreed.
      • If two reads ever disagree, the board shows the fresher one, or the lower price when both are fresh, so a disagreement can only make an edge smaller, never invent one. The leg says what the other read showed.
      • If a book's read fails, its last good read (at most 30 seconds old) stands in for one poll instead of the book vanishing from the board; after that it waits for the book to answer again.

    1. First-quarter lines and FanDuel's basketball laddersv0.38.0

      • First-quarter spreads and totals at BetRivers, Desert Diamond and Hard Rock, kept apart from full-game and first-half lines like every other part-of-the-game market.
      • FanDuel's NBA and NHL alternate spreads and totals are read: they are written without brackets ("76ers +10.5"), so none was read before. FanDuel's NBA first-half lines too.

    2. Kalshi props, switched on for realv0.37.1

      • Kalshi's player props now reach the board. 0.37.0 read them only when in-play reading was off, and production always has it on.

    3. Kalshi player propsv0.37.0

      • ArbWins now reads Kalshi's player props: NBA points, rebounds, assists, threes, steals, blocks and PRA; NFL passing, rushing and receiving lines; NHL goals, assists, points and saves.
      • Each Kalshi rung ("25+ points") pairs with the books' Over/Under at 24.5. On the first live read, two NBA prop edges paired a Kalshi Under against BetRivers.
      • A Kalshi prop on a player who never plays settles at a fair price, where the books void the bet; the pair's settlement line says so.

    4. Kalshi, without the footnotev0.36.1

      • Kalshi legs read like every other book's: no extra line under them.

    5. Kalshi joins the boardv0.36.0

      • ArbWins now reads Kalshi, the CFTC-regulated exchange, for NFL, college football, NBA, NHL and MLB game lines, spreads and totals, priced at the ask plus Kalshi's taker fee.
      • Kalshi often prices games differently from the sportsbooks, so pairing it with them turns up edges a sportsbook-only board never sees.

    6. A sharper home pagev0.35.1

      • The home page has a new look: a soft spotlight behind the headline, live counts that roll as the board updates, and every book we read drifting past in one row.
      • The main button carries a thin light that travels around its edge.
      • Cards light up around your pointer on desktop. On phones everything stays fast and still, and nothing moves for anyone who has reduced motion turned on.

    7. Player-prop prices you can trustv0.34.0

      • Check prices now re-reads a player prop or alternate line straight from the book. Before, it could answer from a copy several minutes old.
      • When a book moves a line that's part of an arb, the arb now leaves the board within about a minute: games with a live edge are re-checked every minute instead of every ten.

    8. The ArbWins logov0.33.0

      • A new logo: two brackets holding a green dot. The brackets are two books' prices, and the dot is the edge between them, which is what every row on the board is.
      • It's on every page, the browser tab, the app icon on your home screen, link previews, emails and the browser extension.

    9. Tidying up after the renamev0.32.0

      • Saved settings such as your theme and dismissed tips carried over to the new ArbWins name.

    10. Arbify is now ArbWinsv0.31.0

      • The site is now ArbWins at arbwins.com: another company was already using the Arbify name. Your account, bets, settings and subscription carry over unchanged.
      • Use arbwins.com from now on. arbify.app was switched off after the move, so links in older emails no longer open; sign in once on arbwins.com.
      • If you use the browser extension, install the new build from Settings and connect it once on arbwins.com.

    11. A $5 day passv0.30.0

      • Not ready for a month? A day pass is $5 for 24 hours of everything in Pro: every pre-game board live, betslip links, price checks and alerts. One payment, nothing renews.
      • Buy another while one is running and it adds 24 hours to the end. Billing shows when your pass runs out and how long is left.

    12. Player props at every book for the NBA and NHLv0.29.0

      • Hard Rock Bet NBA and NHL player props are on the board: points, rebounds, assists, threes and points + rebounds + assists; shots on goal, goals, points, assists and saves, with Hard Rock's alternate lines.
      • BetRivers, Desert Diamond and Bally Bet NBA props now include the Under as well as the Over, and their NHL props are read: shots on goal, goals, points and assists.
      • theScore Bet adds points + rebounds, points + assists, rebounds + assists and NHL assists.
      • Combined lines are matched by what they count, whatever order a book writes them in: a book's "points, rebounds & assists" is never compared with another's "rebounds + assists". Power-play points and three-point field goals are no longer mistaken for points and goals.

    13. Board headlines fit on phonesv0.28.3

      • The three figures at the top of the Arbitrage, +EV and Middles boards no longer run into each other on a phone. A long figure such as a four-figure payout shrinks to fit its column, and the payout gets the widest column.

    14. Ready for the NBA seasonv0.28.2

      • Hard Rock Bet's NBA games are back on the board. Hard Rock listed the new season under a new league page, and Arbify now follows a league to its new page on its own.
      • FanDuel NBA and NHL player props are read: points, threes, rebounds, assists, combos, steals and blocks in basketball; goals, shots on goal, points, assists and saves in hockey, including FanDuel's alternate lines.
      • DraftKings NHL player props are read again: shots on goal, points, assists, saves and goals, with DraftKings' ladders. A change in how DraftKings names those markets had hidden every one.
      • A "steals + blocks" line is no longer compared with a plain steals line at another book.

    15. Arbet is now Arbifyv0.28.0

      • The site, emails and browser extension are renamed Arbify and live at arbify.app. Your account, bets and settings carry over unchanged.
      • If you connected the browser extension, update it and reconnect from Settings once; the old arbet.whoisjason.me address is retired.

    1. Light mode cleaned upv0.27.5

      • The live board on the home page is readable in light mode: a white face with dark figures, where it had shown dark-theme text on a light card.
      • Gold headings, amber warnings, green profit figures and red losses are darker in light mode, so every label on the boards, settings and billing pages meets the contrast standard for small text.
      • Desert Diamond has its own logo, and books without a logo show initials that stay readable on their brand color (white letters on a pale tile had been close to invisible). The book wall on the home page lines up in even rows.
      • The home page names all seven Arizona books Arbify reads directly, and says live games stream as they are played.

    2. theScore Bet live prices in about a secondv0.27.4

      • The live board now hears theScore Bet the moment its in-play NFL, college football, NBA, NHL and MLB prices move, instead of checking every few seconds. Its league pages run several seconds behind its live prices; the board now follows the live prices themselves.
      • A theScore line that has just appeared on a live game waits until its price is confirmed, so the board shows no price for a moment rather than one that may already have moved.

    3. No +EV from a stale reference pricev0.27.3

      • When three or more Arizona books all price a bet well away from the sharp reference, the reference is the stale one, and the +EV board no longer lists it. One player prop had read +49.9% because of that; the board's best row is now under +10%.

    4. Fair prices that do not overrate longshotsv0.27.1

      • The +EV board, the consensus panel and the no-vig calculator now take the margin out with the power method, which removes it from the longshot where books put it. The old proportional method overrated big underdogs: college moneylines such as Kent State at +1100 read +34.8% EV against Pinnacle; they now read about +1.5%. On one read of every Arizona book, bets at +0.5% or better went from 203 to 123 and the best from +34.83% to +6.52%.
      • A soccer moneyline is only ever compared with a reference that prices the same outcomes, so a two-way price never meets a three-way fair chance, and Asian quarter lines are never priced.
      • The +EV guide and the no-vig and EV calculators show their worked examples with the new method.

    5. Soccer: nine leagues at all seven Arizona booksv0.27.0

      • The board now reads the Premier League, La Liga, Serie A, Bundesliga, Ligue 1, the Champions League, MLS, Liga MX and the Brasileirão at DraftKings, FanDuel, BetRivers, Desert Diamond, Bally Bet, Hard Rock Bet and theScore Bet.
      • Soccer arbs come from the three-way result (home, draw, away: three bets, one at each book pricing it best), totals and two-way spreads. A two-way "draw no bet" price never fills a leg of a three-way arb, and Asian quarter lines (±0.25, 2.75) are left out, since they split the stake over two lines.
      • Soccer markets settle on 90 minutes plus stoppage time at every book; extra time and penalties never count. Soccer rows carry the not-verified mark until each book's house rules have been read.

    6. BetMGM, Caesars, Fanatics and bet365 through your own browserv0.26.0

      • The Arbify browser extension checks your legs at BetMGM, Caesars, Fanatics and bet365 against those books' own pages when you open them: the leg on the board says whether the price still holds and the arb still pays, or what it moved to. Nothing leaves your browser for this.
      • If you choose to share, the prices those pages show you reach every member's board, marked "via Arbify users" with how long ago they were seen. Sharing is off until you agree to exactly what is sent; Arbify checks each price against the other books and drops any that do not fit.
      • Settings has a Browser extension section in a browser where the extension is installed, to connect or disconnect it.
      • "Check prices now" says when a leg is a price members shared, rather than a feed Arbify reads itself.

    7. Live prices in about a secondv0.25.15

      • The live board now hears BetRivers, Desert Diamond, Bally Bet, DraftKings and Hard Rock Bet the moment their in-play prices move, instead of checking every few seconds, and FanDuel's in-play prices are re-checked every 2 seconds. Live edges are re-checked every second.
      • A live edge leaves the board as soon as either price moves or the book pauses betting, so what you see is what you can still take.

    8. DraftKings first-half linesv0.25.14

      • DraftKings' first-half spreads and totals, alternate lines included, now pair with the other books' first-half lines.

    9. theScore Bet player propsv0.25.10

      • theScore Bet's player props are on the board: passing, rushing and receiving yards, receptions, passing touchdowns and completions in football; points, rebounds, assists, threes and points-rebounds-assists in the NBA; shots on goal, points and saves in the NHL.

    1. First-half spreads and totalsv0.25.8

      • First-half spreads and totals from FanDuel, Hard Rock Bet, BetRivers and Desert Diamond are on the board, alternate lines included. A first-half price only ever pairs with another first-half price, and every such row says "1st half".
      • Tracking a first-half bet works as before; it is not settled automatically from the final score, since the half-time score decides it.

    2. BetRivers and Desert Diamond alternate linesv0.25.6

      • BetRivers' and Desert Diamond's full ladders of alternate spreads and totals are compared against every other book, as DraftKings', FanDuel's and Hard Rock's already are.

    3. Hard Rock Bet player propsv0.25.5

      • Hard Rock Bet's football player props are on the board: receptions, receiving, rushing and passing yards, passing touchdowns, interceptions, completions, attempts and longest plays, every rung of each ladder. Hard Rock props against BetRivers and DraftKings were the largest group of arbitrage Arbify was not showing.

    4. Every alternate line and player prop, all the timev0.25.4

      • Fixed a fault that kept dropping most alternate lines and player props between refreshes whenever more than one sport was being read. They now stay on the board and refresh on schedule for every sport, which is where most arbitrage between the Arizona books sits.

    5. Desert Diamond and Bally Betv0.25.3

      • Desert Diamond is on the board, read straight from the book every 20 seconds with its alternate lines and player props. It sets its own moneylines, so it brings prices no other Arizona book has.
      • Bally Bet is read straight from the book too, so you can see when it matches the best price at another book and spread your action across one more account.

    6. FanDuel's alternate linesv0.25.2

      • FanDuel's full ladder of alternate spreads and totals is now compared against every other book, the way DraftKings' already was. Alternate lines between those two books were the largest single source of arbitrage Arbify was missing.

    7. College football and the MLB playoffsv0.25.0

      • College football is on the board from all five Arizona books: DraftKings, FanDuel, BetRivers, Hard Rock Bet and theScore Bet, with alternate lines and player props where the books post them.
      • MLB playoff games are on the board from the same five books.
      • College football and MLB bets you track settle themselves from the final score, like NFL, NBA and NHL bets already do.

    8. The home page opens with today's numbersv0.24.13

      • The edges, books and prices on the home page are there the moment it opens, instead of filling in a second later.

    9. Live numbers that never get stuckv0.24.6

      • When Arbify is updated while you have a board open, the board reconnects by itself and carries on, instead of stopping or saying you were signed out.
      • A tab you leave in the background pauses its live updates after a minute and catches up the moment you come back to it.

    10. Numbers that update the moment prices movev0.24.5

      • The home page, the free board, +EV and middles now update the moment new prices come in, instead of checking every so often.
      • Board updates are about a seventh of the size they were, which is easier on a mobile data plan.
      • Pages open with far fewer downloads: every sportsbook and team logo comes in one small image, and a page is fetched when you point at its link rather than for every link on screen.

    11. Odds pages and the track record load instantlyv0.24.2

      • Today's odds for each league and the record of every edge found are served ready-made and refreshed every minute, so they open straight away even when the site is busy.

    12. See every edge, whatever your planv0.24.1

      • Every edge is on the board for everyone, with what it would pay on your bankroll. Free accounts act on edges up to +1%, Pro up to +3%, and Live on all of them; a bigger edge shows its game, market and payout with a button to unlock it.
      • The board's summary shows the best edge open right now even when your plan does not cover it, so you can see what you are missing.

    13. Faster everywhere, and boards that fit a phonev0.24.0

      • The home page, guides and calculators load straight away: they no longer wait on the server for each visit.
      • The boards open faster and stay quick while live games update every few seconds, on desktop and on a phone.
      • On a phone the arbitrage, +EV and middles boards fit the screen again instead of scrolling sideways.
      • A long matchup wraps between the two teams, so a team's logo always sits next to its name.
      • During games the board downloads a small update every few seconds instead of the whole board, which is easier on a mobile data plan.

    14. Live prices from five Arizona booksv0.21.1

      • DraftKings, FanDuel, BetRivers, Hard Rock Bet and theScore Bet are read in play: the Live tab pairs their prices on games in progress, only while both are seconds old and the market is open.
      • FanDuel's pre-game prices now come from its real-time price feed instead of a page that could be half a minute old.

    15. Live, a tier of its ownv0.21.0

      • The arbitrage board has Pre-game, Live and Low holds. Live shows arbs on games in progress, and pairs two prices only when both are seconds old.
      • Live is a tier above Pro, shown on the pricing page.

    16. Low holdsv0.20.1

      • Switch the arbitrage board to Low holds: the pairs that cost the least to bet both sides, cheapest first, with each side's stake. Useful for clearing a bonus playthrough or moving money between books.

    17. Bonus bet converterv0.20.0

      • Got a bonus bet from a sportsbook? Pick the book and the amount: Arbify finds where to bet it and where to hedge it, and shows the cash you keep whichever side wins.
      • A free bonus bet calculator for any two prices.

    18. Hard Rock Bet and theScore Bet, livev0.19.0

      • Hard Rock Bet and theScore Bet are now read straight from their own Arizona sportsbooks every 20 seconds, instead of twice a day. That makes five Arizona books on the live board.
      • On the +EV board, every bet shows what its stake wins if it hits.

    19. See what you win before you betv0.18.0

      • Every arb leads with the dollars your bankroll wins, not just the percentage.
      • Open "What you win" on any arb: what each side pays if it hits, a bar for every book, and stakes you can type. Change one stake and the other rebalances so both tickets pay the same.
      • The live board on the home page shows each edge as dollars won on $1,000.

    20. Stakes you can read at a glancev0.17.1

      • Every leg now says how much to bet, next to its price and on its betslip button, and it changes as you type your bankroll.
      • The bankroll field edits like any other box: clear it, type a new amount, and the stakes follow.
      • Tell Arbify the most each book still lets you bet (Settings, next to each book) and every stake split respects it.
      • Log a +EV bet to the tracker straight from its row.

    21. Arizona books onlyv0.17.0

      • Every book on the board now takes bets in Arizona. Pinnacle, Bovada and BetOnline are gone from the boards, the odds pages, the track record and the alerts.
      • The +EV board still prices fair odds from Pinnacle's line, the sharpest public price there is, but Pinnacle is never a bet on the board.
      • Push alerts say plainly when a browser cannot receive them yet, instead of turning on and staying silent.

    1. Scoreboards on +EV and middlesv0.23.4

      • The +EV board opens on its count, the best expected value and the expected profit of betting them all at quarter Kelly on your bankroll.
      • The middles board shows the widest window and what the best middle pays if it lands, next to its estimated chance.

    2. The home page shows the board lit upv0.23.2

      • The board on the home page is the night scoreboard with each payout on its own stub, and the page now says plainly that Pro covers every pre-game board while Live sits above it.

    3. A pricing page that shows what Pro is worthv0.23.1

      • Set your bankroll on the pricing page and see what a typical edge pays and how many edges cover Pro for the month.
      • Free, Pro and Live side by side, the billing terms in four plain lines, and straight answers to the questions people ask before a trial.
      • The track record now counts pre-game edges only; live arbs are their own tier.

    4. A board with a scoreboard and bet slipsv0.23.0

      • The board opens on a scoreboard: how many edges are open, the best one, and what it pays on your bankroll. Come back later and it tells you how many opened while you were away.
      • Each arb reads like a bet slip. The payout tears off at the bottom, brighter the bigger the edge, and the amount every outcome pays is the big number.
      • Every leg and betslip button carries its sportsbook's color, and stakes and payouts roll to their new values when you change your bankroll.

    5. Closing line value, automatic grading, four more calculatorsv0.22.2

      • The bet tracker shows closing line value for every pre-game bet: your price against the book's last price before kickoff, and your average across bets.
      • Open bets are graded from final scores on their own, about every 15 minutes, and Settle now does it on demand.
      • Free EV, Kelly, hold and parlay calculators, each with a worked example.

    6. Live alerts and trial remindersv0.22.1

      • Live subscribers with push on get a notification for a new live arb. It expires after 20 seconds, so a price that is already gone never buzzes late, and tapping it opens the Live tab.
      • Two days before a free trial ends, Arbify emails the date the card is charged and the amount, with a link to cancel. The billing page and terms say how billing and refunds work.
      • A pair that adds up to exactly 100% (+2500 against -2500) is no longer listed as an arb.

    7. Live arbs refresh every few secondsv0.22.0

      • While a game is on, the five live books are re-read every 6 seconds for that sport, so a Live arb shows up and disappears with the prices instead of on the 20-second board cycle.

    8. This pagev0.16.1

      • A public list of every release and what it changed. The version in the footer links here.

    9. Push alerts and a better board on tabletsv0.16.0

      • Pro accounts can turn on push notifications in Settings and hear about a new edge at their books within seconds.
      • Edge counts now mean what they say: a positive edge on a game that has not started. The best edge shown never includes a likely pricing error.
      • On tablets the boards show two columns of cards so the betslip buttons are always in view.
      • On the free board, a game opens its odds page with every book's line.

    10. Odds for every game, side by sidev0.15.0

      • New odds pages for the NFL, NBA and NHL: every book's moneyline, spread and total for every upcoming game, with the hold and which book is off the market.

    11. Bet tracker, email alerts and the daily recapv0.14.0

      • Log both legs of an arb from any row, settle them, and see your profit and ROI by book. Free for every account.
      • Pro accounts can get new edges by email. Everyone with a confirmed email gets a short recap of yesterday's edges at their books, with one-click unsubscribe.
      • Each arb marks the leg to place first: the price furthest above the other books, the one most likely to move.
      • Stake splits respect Pinnacle's published maximum bet on each market.
      • Guides to arbitrage betting, +EV betting and middles.

    12. Our track record, in publicv0.13.0

      • Every edge Arbify found in the last 30 days, how big it was and how long it stayed open.
      • Each board row says how long edges in that market usually last.
      • New accounts pick the sportsbooks they have, so the board only shows arbs they can place.
      • Arbify installs to your phone's home screen.

    13. A free board, line movement and free calculatorsv0.12.0

      • Free accounts see the real arbitrage board a minute behind, without betslip links.
      • The game view shows each book's line movement and whether the books agree on the price.
      • Free arbitrage, hedge and no-vig calculators and an odds converter.
      • A public table of how each book settles overtime, shootouts and player props.

    14. Steadier feeds, cross-checked pricesv0.11.0

      • Feeds retry and back off on their own, and every poll checks the books against each other for lines that do not make sense.

    15. Clearer pricingv0.10.0

      • Pricing shows the books on the board today and what Pro costs per day.
