How We Evaluate Gambling Bonuses

How we compare wagering requirements, game contribution, time limits, maximum bets and expected gambling cost when explaining bonuses.

Quick answer

We do not judge a bonus by its headline percentage alone. The conditions determine how much qualifying gambling may actually be required.

Inputs

Offer amount, deposit requirement, requirement base, wagering multiplier, contribution, eligible games/markets, maximum bet, expiry and cashout restrictions.

Casino cost model

Where appropriate, qualifying action is multiplied by a rules/paytable-specific house-edge estimate.

Sportsbook cost model

Sports promotion analysis uses offered prices, market overround and stake-return rules rather than casino house-edge formulas.

Variance

Expected value is not a guarantee. Bankroll exhaustion before completion can materially change realized outcomes.

Evidence hierarchy

Promotion-specific claims must come from current operator terms; jurisdictional advertising/inducement rules come from regulators; mathematical formulas are shown explicitly.
