On average it's worth more than it costs to clear. Just remember most single sessions won't look like the average.

A bonus is never a way to make money. Set a deposit limit before you play.

How this is calculated

  • Total stake = (bonus, or bonus + deposit) × wagering requirement.
  • Expected cost = total stake × (100% − RTP). RTP is a long-run average, not what happens in one session.
  • Average value = bonus − expected cost. It ignores game restrictions, bet limits and expiry, which usually make a bonus worth less.
