Arbitrage (Arb)
Placing bets on all outcomes of a game across different sportsbooks to guarantee a profit regardless of result.
American Odds
The standard odds format in the US. Negative numbers (e.g. -150) show how much you bet to win $100. Positive numbers (e.g. +130) show how much you win on a $100 bet.
Bonus Bet
A free bet token from a sportsbook. If it wins, you collect the winnings but not the stake. If it loses, you lose nothing since it was free.
Bookmaker / Book
A company that accepts sports bets, such as DraftKings, FanDuel, BetMGM, Caesars, or theScore Bet.
Decimal Odds
An alternative odds format popular in Europe. Multiply your stake by the decimal to get total payout. E.g. 2.5 odds on a $100 bet = $250 total return.
Favorite
The team or player expected to win. Shown with negative American odds (e.g. -150).
Handle
Total amount of money bet on a game or at a sportsbook.
Hedging
Placing a bet on the opposite side of an existing bet to reduce risk or guarantee profit.
Implied Probability
The probability of an outcome implied by its odds. -110 implies about 52.4% probability.
Juice / Vig
The sportsbook's built-in profit margin. Most markets are set at -110/-110, meaning you risk $110 to win $100 — the $10 extra is the vig.
Line
Another word for the odds on a game.
Moneyline (ML)
A bet on which team wins outright, with no point spread. This is what we scan for arb opportunities.
No Sweat Bet
A bet where if you lose, the sportsbook refunds you as bonus bets up to a specified amount. Also called First Bet Insurance or Risk-Free Bet.
Overround
The sum of all implied probabilities for all outcomes in a market. A normal market is over 100% (that's the vig). An arb exists when it's under 100%.
Point Spread
A handicap given to the underdog to level the betting field. The favorite must win by more than the spread.
Profit Boost
A promotion that increases your potential winnings by a set percentage. Also called an Odds Boost.
Sharp
An experienced, sophisticated bettor who often moves lines with large, informed bets.
Square
A casual, recreational bettor. Most bonus promotions target squares — we help you benefit from those promotions.
Stake
The amount of money you bet.
Underdog
The team or player expected to lose. Shown with positive American odds (e.g. +130).
Unit
A standardized bet size used to track performance. Many bettors use 1% of their bankroll as 1 unit.
Withdrawal / Cashout
Taking money out of your sportsbook account back to your bank account or payment method.
