Short answer

• For high rollers in Colombo right now, the top choice is the new integrated resort City of Dreams Sri Lanka (the luxury casino at Cinnamon Life / Nüwa) — it was built specifically to attract VIPs and has private gaming salons and high‑limit tables.

Practical tips for high rollers

• VIP contact: Ask each casino for their VIP host or private salon manager ahead of arrival — hosts arrange private tables, credit/marker terms, comps, and limo/airport transfers.
• Membership & minimums: Many VIP benefits require membership or a minimum play/points threshold. Clarify minimum table limits, credit availability, and comp policies before you play. (DarkEvents.lk)
• ID & entry: Foreigners typically must show passports to enter casinos in Colombo; dress codes and security checks are common. (srilankaholidayguru.com)
• Local rules & regulation: Sri Lanka expanded casino capacity recently and opened large integrated resorts to attract high‑end tourism; regulatory rules and offerings can evolve — if you need the very latest on licensing, hours, or new VIP offerings I can check current official notices.
