Question 1

What is arbitrage betting?

Accepted Answer

Arbitrage betting (also called "arbing" or "sure betting") is the practice of placing bets on all possible outcomes of an event across different bookmakers so that the combined implied probability is below 100%. When that happens, a profit is mathematically guaranteed regardless of the result. The arbitrage calculator checks whether the odds you enter create such an opportunity and shows you the exact stake to place on each outcome.

Question 2

What is the sportsbook house edge?

Accepted Answer

The house edge (also called the vig, juice, or overround) is the margin a sportsbook builds into its odds. If you convert every outcome of a market to implied probability and the total exceeds 100%, the excess is the bookmaker's cut. For example, two outcomes both priced at 1.95 imply 51.28% each — 102.56% combined — so the sportsbook keeps roughly 2.56% of the money wagered on that market. The edge calculator computes this from the odds you enter.
