Is a 40× wagering requirement worth it?

In Great Britain, licensed casinos have been prohibited from setting bonus wagering above 10× since 19 January 2026 — so 40× now appears mainly on non-UK sites. On a $100 bonus, 40× requires $4,000 in bets ($8,000 on deposit + bonus), costing $160 at 96% RTP and leaving you $60 down.
