Bonuses: what it costs to clear them, game by game

A bonus is not extra money; it is a contract with conditions. Those conditions interact with games in a way few reviews explain: the game's RTP sets the average cost of meeting the wagering, and its volatility decides whether you get there at all. This section translates promotions into those two variables.

What you will not find here

We do not publish Rabona's percentages, amounts or wagering multiples as if they were fixed. Promotions change and depend on country and account; what applies to you is on the operator's promotions page and in its terms. Amounts below are in units of your account currency and are illustrative only.

The sum that decides whether a bonus is worth it

If a bonus requires a total amount to be wagered before withdrawal, every unit wagered loses, on average, the house edge of the game you use.

ItemExample
Bonus100
Wagering30× the bonus
Total to wager3,000
RTP of chosen game96%
Expected loss while wagering3,000 × 4% = 120

Here the expected cost of clearing (120) exceeds the bonus (100). With lower wagering or a higher-RTP version the result changes — which is why you do the sum before accepting.

Volatility: the other half

Expected loss is an average. On a high-volatility slot, the most likely outcome is running dry halfway through, although now and then a big feature clears everything with room to spare. On a low-volatility game the balance drains more evenly and predictably. Details in wagering and game weighting.

Seasonal and limited-time offers

Holiday campaigns, tournaments and time-limited reloads come and go. The urgency is part of the design. A promotion that ends tonight is no reason to deposit more than planned; run the same cost check and let it pass if the sum does not work.
