A complete beginner's guide to understanding online casino bonuses, how they work, different types, and what you need to know before claiming one.
Understanding the fundamentals
An online casino bonus is a promotional offer that gives you extra funds or free spins to play with. Casinos use bonuses to attract new players and reward existing ones. The most common type is a deposit match bonus, where the casino matches a percentage of your deposit (e.g., 100% up to $1,000).
Common bonus categories explained
The most common type. Casino matches your deposit by a percentage (50%-200%) up to a maximum amount.
Free money or spins given without requiring a deposit. Great for testing casinos risk-free.
Free spins on specific slot games, either standalone or bundled with deposit bonuses.
Bonuses for existing players on subsequent deposits, usually smaller than welcome bonuses.
Percentage of losses returned to you, usually weekly or monthly. No wagering requirements.
Exclusive bonuses for players making large deposits, with higher limits and better terms.
The most important bonus term
Wagering requirements (also called playthrough or rollover) determine how many times you must wager the bonus amount before you can withdraw winnings. This is the single most important factor in bonus value.
What else you need to know
Not all games contribute equally to wagering requirements. Slots usually contribute 100%, while table games and live casino contribute 10-20% or are excluded entirely.
Most bonuses have a maximum bet limit (usually $5-$10 per spin/hand) while wagering. Exceeding this limit can void your bonus and winnings.
Bonuses expire after a certain period (typically 14-30 days). You must complete wagering requirements before the deadline or forfeit the bonus and any winnings.
Some bonuses (especially no deposit bonuses) have maximum withdrawal limits. Even if you win $10,000, you might only be able to withdraw $100-$500.
