Just seen this thread and had to chip in. What actually matters here is when it comes to Casinodays and Rainbow Riches.
The January 2026 UKGC cap at 10x wagering has genuinely improved things for UK players. Any site offering more than 10x on a bonus is worth questioning.
The Megaways mechanic generates up to 117649 ways to win which sounds impressive but the base game wins are usually tiny.
EV check on Casinodays welcome bonus: With 35x wagering on a £100 bonus, you need to stake £3500. At a 4% house edge that costs £40 to complete. Expected value: £40. Negative EV — treat as entertainment cost, not profit opportunity.
Key stats: Casinodays — founded 2020, 2,500 games, withdrawals typically within 3 hours. Rainbow Riches — Barcrest, 95% RTP, medium variance.
GamStop is worth knowing about even if you are not using it. It is the UK national self-exclusion scheme.
