Decimal Odds function: Used in Europe since they reveal how much a successful wager returns with the stake integrated. Users placing a $10 bet receive $25 from the 2.50 odds system.
Fractional Odds: Popular in the UK, these represent the profit relative to the stake. When you wager $1 using a 5/1 odds format, you will win $5 in addition to your stake.
Moneyline Odds: Viprow.us.com displays moneyline odds in two formats, where positive numbers (+200) represent the winnings from a $100 bet, yet the site also shows negative numbers (-150), which indicate the amount necessary for a $100 win.
