Notes on these figures
'More than 500 slot machines' and 37 live table games after the May 2026 drydock (World Casino Directory, SiGMA, Marine Insight).
Five-week Royal Amplified drydock (spring 2026) expanded Casino Royale into The Attic comedy club/Entertainment Place and Crown Lounge space, making it the fleet's largest casino (until Legend's debut). SiGMA says the renovated Deck 4 'exceeds 12,000 sq ft' (not clearly the casino's size, so not recorded). Pre-refit CruiseMapper figure (456 slots/27 tables) is outdated.
Reported slot machines
