William Hill’s “HILL200” gave me 200% deposit match BUT only for “selected games” (read: Mega Moolah at 92% RTP). Transferred £500 balance, played 3 hours, ended with £90. Meanwhile, Casimba’s “CASH50” code (no deposit) let me play 95%+ Pragmatic slots. Cashed out £150. Older casinos = slower RTP bleed.
