Frequently Asked Questions

What is +EV betting?

+EV (positive expected value) betting means placing bets where the true probability of winning is higher than the implied probability from the odds offered. Over time, +EV bettors profit because math is on their side.

What is arbitrage betting?

Arbitrage betting (or "arbing") involves placing bets on all outcomes of an event across different sportsbooks to lock in profit regardless of the result. This is possible when odds discrepancies exist between books.

What is CLV (Closing Line Value)?

CLV measures whether you got better odds than the closing line (the final odds before an event starts). Consistently beating closing lines is the gold standard for measuring betting skill. Research shows ~52% of your CLV converts to actual ROI.

What is a low hold market?

A low hold (or low vig) market is one where the combined house edge across all outcomes is minimal. By shopping for the best odds across sportsbooks, you can create effective markets with less than 1% hold.

How do I convert free bets to cash?

Use your free bet on a long-shot selection (+300 or higher), then hedge on another sportsbook with the opposite outcome. Our free bet converter calculates optimal stakes to maximize your estimated conversion value.

What is sharp money?

Sharp money refers to bets placed by professional bettors. When lines move against public betting percentages (reverse line movement), it often indicates sharp action. Following sharp money can be a profitable strategy.
