How it works
Three simple steps. No experience needed.
We do the math for you.
01
Find an Opportunity
Our scanner checks the sportsbooks we cover against each other. When two books disagree on odds enough to create a profit gap, we flag it.
Example
Example: DraftKings has Chiefs at +130, while FanDuel has Bills at +120. Betting both sides = locked-in profit on both sides.
02
Calculate Your Bets
Our calculator tells you exactly how much to bet on each side and at which sportsbook — no math required. It works for standard arbs AND sportsbook promos like free bets.
Example
Example: Bet $489 on Chiefs, $511 on Bills → about $124 profit regardless of who wins.
03
Collect Your Profit
Place the two bets as shown. One side always wins, and the math ensures you always come out ahead. Withdraw your profits and do it again.
Example
Example: Chiefs win → you collect $1,124 from DraftKings — about $124 more than the $1,000 you staked in total.
Shop the line
The same game, priced differently
Books disagree on price constantly. Betting the best available number on every wager is the simplest edge there is — here's what that looks like right now.
