the problem in plain language
A bonus can be worse than no bonus at all
If the wagering requirement forces you to push far more volume than the bonus is worth, the house edge picks up the bill. That is exactly what happens here: the bonus feels free, but the math does not.
30× example
30× on a €100 bonus means roughly €3,000 of forced action before you can freely cash out.
house edge
Even a modest house edge eats more out of that volume than the bonus ever adds.

where the damage comes from
Why these bonuses mathematically sink below zero
bonus on paper
€100 to €500
required wagering
often thousands in turnover
end result
negative EV
The formula is simple. If your expected loss during the wagering phase is larger than the bonus value, the bonus is a worse deal than skipping it. This page exists to surface that hidden bill.
