What the bonus is really worth
To unlock the full $750 bonus you deposit $600 and must wager $26,250 in total. The expected cost of that wagering depends on the RTP of the games you play:
| Slot RTP | Expected loss while wagering | Expected value |
|---|---|---|
| 96.0% (typical slot) | $1,050.00 | −$300 |
| 97.5% (high-RTP slot) | $656.25 | +$94 |
| Free spins: 125 × $0.20 on Sweet Bonanza ($25 face value, 96% RTP) | No wagering on spin winnings | +$24 |
The estimate on our offer cards, ≈ −$26, uses a $100 deposit at 96% RTP and adds the 125 free spins, which is why it differs from the maximum-deposit figures above. Choosing higher-RTP slots makes a measurable difference. Learn the method in our wagering requirements guide or check the maths in the wagering calculator with the card's numbers filled in.
