Implied probability is the odds expressed as a percentage. On a two-way market the two percentages add up to more than 100: the excess is the book margin.

Questions about wagering and limits

How is the wagering requirement calculated?

The requirement is the product of the wagering multiplier and the qualifying balance. Where terms specify bonus-only wagering, the multiplier applies to the credited bonus alone. Where terms specify bonus and deposit, the multiplier applies to their sum, which doubles the turnover for an equal match rate. Game contribution then divides into that figure: a category contributing twenty percent requires five times the stated turnover before the condition is considered met.

What does the maximum bet clause do?

The maximum bet clause caps the stake permitted on any single round while a wagering requirement remains outstanding. Exceeding the cap is treated as a breach of the promotional terms and generally results in forfeiture of the bonus balance together with any winnings derived from it. The cap applies per round rather than per session, so a single oversized stake is sufficient to trigger the clause.

Why do withdrawal limits differ by method?

Withdrawal caps reflect the settlement characteristics of each payment rail. Card payouts are processed through acquiring banks and are subject to chargeback windows, which is why daily caps are lower and processing runs to several business days. Electronic wallets settle within the provider network and clear faster. Cryptocurrency transfers settle on their respective chains and carry the highest daily ceilings, with confirmation times measured in minutes rather than days.
