Casino / bonus mechanics

What are wagering requirements?

Wagering requirements tell you how much play is needed before a bonus or bonus-linked winnings can become fully withdrawable. This is one of the clearest topics for building trust around casino content.

The simple meaning

A casino bonus often comes with a rollover rule such as "35x bonus" or "35x bonus + deposit". That multiplier tells you how much total stake volume must be completed before the funds are fully cleared.

A quick example

If you receive a EUR100 bonus with a 35x bonus requirement, the basic wagering target is EUR3,500. If the term is 35x bonus + deposit and you deposited EUR100 as well, the target becomes EUR7,000.

Bonus setup Base amount Multiplier Total wagering
EUR100 bonus, 35x bonus EUR100 35x EUR3,500
EUR100 deposit + EUR100 bonus, 35x bonus + deposit EUR200 35x EUR7,000

The hidden details that change everything

The raw multiplier is only the start. Readers should also look for:

  • Game weighting, because some slots count 100% while table games may count far less
  • Maximum cashout rules, which can cap the real value of the offer
  • Bonus expiry windows, because short time limits can make generous-looking bonuses unrealistic
  • Eligible games, because the best RTP games are often excluded
This is why bonus size alone is a weak comparison metric. WikiOne should explain the mechanic first, then send the reader to practical offer comparisons only after the reader understands what the terms mean.
