How each book settles the bets ArbWins pairs
An arbitrage bet is two bets that cannot both lose. That is only true when both sportsbooks grade the market the same way. Overtime at one book and regulation time at another, or a shootout goal that counts at one and not the other, turns a locked return into a coin flip. This is the table every row on the board is checked against.
What the mark on each row means
- Settles the same
- Both books apply the same rule for this sport and market, and ArbWins has read that rule in each book's house rules.
- Settles differently, or not verified
- The row says exactly which book differs and how, or that a rule has not been verified for one of the books. Unknown is never treated as equal.

Regulation-time markets
Several books also list “60 minutes” or “regulation time” versions of the NHL moneyline and three-way markets that pay out on a tie. ArbWins reads them as their own market and never pairs one with a full-game price, because a game that goes to overtime grades them in opposite directions.
Player props
Every book ArbWins reads voids a player prop when the player does not take part, but the exact test differs: dressed, one snap, one minute played. ArbWins has not yet verified each book's rule from its own house rules, so every prop row is marked player prop, voids if the player does not play and not verified until it has. Treat prop arbs on questionable players as a bet, not a lock.
Not verified yet
Baseball (MLB): listed-pitcher rule varies by book. Soccer: 90 min + stoppage time; 3-way, a draw is a result. Rows in these sports carry the not-verified mark until the rules are read book by book.
House rules last reviewed on 2026-10-13. Sportsbooks change their rules; when a row on the board disagrees with this page, the board is newer.
ArbWins checks this for you on every row
Each arbitrage, +EV bet and middle on the board carries the settlement mark above, so the trap that voids arbs is visible before you open a betslip.
