SINGAPORE--Singapore's casino regulator has fined the city-state's two casinos for disciplinary breaches committed from May to October last year.

Marina Bay Sands, run by U.S. gaming group Las Vegas Sands Corp. (LVS), was fined 357,500 Singapore dollars (US$286,800) for several failures in enforcing the country's tough casino-entry restrictions, the Casino Regulatory Authority said late Wednesday in a statement.

Resorts World Sentosa, operated by Genting Singapore PLC (G13.SG) was asked to pay S$140,000 in fines for similar breaches, the regulator said.

Under Singapore law, casino operators must ensure that Singapore citizens and permanent residents seeking entry into their casinos pay entry levies of S$100 a day and S$2,000 a year, and check that these patrons don't exceed their allotted period of stay.

Operators must also ensure that all patrons are at least 21 years old and haven't been banned from entering casinos here under mandatory or voluntary programs.

Separately, the regulator censured RWS for three instances of allowing minors to enter or remain in its casino, and issued a warning to MBS for a breach of gaming-equipment rules in October.
