Expert Tips to Maximize Your Bonus

Low Wagering is Key

Always prioritize bonuses with low (under 35x) or no wagering requirements.

Check Game Contributions

Slots usually contribute 100% to wagering, but table games might contribute only 10% or less.

Mind the Expiry Date

Most bonuses expire within 7-30 days. Make sure you have enough time to meet the requirements.

Always Read the Fine Print

A great bonus can be spoiled by tricky terms. Watch out for:
