Start with eligibility
Check whether the promotion applies to your account and location. Some offers require an opt-in before a deposit; others exclude particular payment methods. Never assume an offer is automatically applied.
Follow the wagering calculation
Look for the wagering multiplier and whether it applies to the bonus alone or the deposit plus bonus. Check which games contribute, the maximum stake, expiry time and any withdrawal cap.
Keep your freedom to decline
A bonus is optional. If its conditions are unclear or require spending more than planned, skip it. Promotions do not make gambling profitable.
