Right, I can actually help with this one. From what I have seen when it comes to Casumo and Thunderstruck II.
Sticky bonuses where you cannot withdraw the bonus amount itself are generally worse than cash bonuses even with a lower headline figure.
RTP is the return to player percentage over millions of spins. In any individual session it means almost nothing.
EV check on Casumo welcome bonus: With 30x wagering on a £100 bonus, you need to stake £3000. At a 4% house edge that costs £20 to complete. Expected value: £20. Negative EV — treat as entertainment cost, not profit opportunity.
Key stats: Casumo — founded 2012, 1,800 games, withdrawals typically within 24 hours. Thunderstruck II — Microgaming, 96.65% RTP, medium_high variance.
If a casino is asking for documents before you can withdraw that is standard KYC not a scam. Upload them early to avoid delays.
