Understanding Bonus Terms Before You Claim

  1. Wagering requirement: The lower, the better. Under 30x is generally reasonable.
  2. Game restrictions: Some games contribute less (or nothing) toward meeting wagering requirements.
  3. Time limit: Bonuses typically expire within 7–30 days.
  4. Maximum bet: Many bonuses restrict how much you can bet per spin/hand while using bonus funds.
  5. Maximum withdrawal cap: Some bonuses limit how much bonus-derived winnings you can cash out.
