Matched Betting

A strategy that uses bookmaker promotions, free bets, and bonuses to guarantee a profit by backing at a bookmaker and laying at an exchange. Matched betting is technically risk-free when executed correctly and is a common starting point for new bettors to build a bankroll.

Kelly Criterion (Kelly)
A mathematical formula used to determine the optimal stake size for a bet based on your edge and the odds offered. Formula: Kelly Stake = (bp - q) / b, where b = decimal odds - 1, p = probability of winning, q = probability of losing (1 - p). Many bettors use a fraction of Kelly (e.g., quarter Kelly) to reduce variance.
Poisson Distribution
A statistical probability distribution commonly used to model the number of goals, points, or events in a sports match. By estimating the expected average (lambda) of events, the Poisson formula calculates the probability of exactly 0, 1, 2, 3, etc. events occurring. It is the foundation of many football betting models.
Risk of Ruin (RoR)
The probability that a bettor will lose their entire bankroll given their edge, bet size, and number of bets. Even profitable bettors face risk of ruin if they stake too large a percentage of their bankroll. Reducing unit size dramatically lowers risk of ruin. A common target is keeping RoR below 1%.
Regression to the Mean
A statistical phenomenon where extreme results tend to move closer to the average over time. In betting, a team on a long winning streak is likely to see their performance normalize. Understanding regression helps bettors avoid overreacting to short-term results and identify value where the market has overcorrected.
Return on Investment (ROI)
A percentage that measures the profitability of your betting relative to the total amount wagered. Formula: ROI = (Total Profit / Total Staked) x 100. For example, if you bet $10,000 total and made $500 profit, your ROI is 5%. A positive ROI indicates long-term profitability. Professional bettors typically achieve 2-10% ROI.
Dutching
A strategy where you back multiple selections in the same market with different bookmakers, distributing stakes to ensure the same profit regardless of which selection wins. Unlike arbitrage, Dutching does not guarantee a profit on every outcome but can distribute risk while targeting specific outcomes you consider underpriced.
