How the six operators fit together
Every casino you can walk into in Macau belongs to one of six companies. That is not a coincidence of the market; it is how the system is built. The Macau government awards a small number of gaming concessions, and only the companies holding them may operate casinos. The six current concessionaires are Sands China, Galaxy Entertainment Group, Melco Resorts, MGM China, SJM and Wynn.
Each company's name tells you something about its background. Sands China is the Macau arm of Las Vegas Sands; MGM China is tied to MGM Resorts International; Melco Resorts is part of Melco Resorts & Entertainment; Wynn is the Macau operation of Wynn Resorts. Galaxy and SJM are the two with roots closer to home: Galaxy is a Hong Kong-listed group that built its fortune in Macau, and SJM is the local operator descended from the company that held Macau's original gaming monopoly10.
The practical effect for you as a visitor is simple. When you pick a casino, you are really picking an operator, and each operator has its own style, its own resorts and its own corner of town. The Cotai Strip, the reclaimed land between the islands of Taipa and Coloane, is where the biggest resort complexes sit, and it is dominated by Sands, Galaxy, Melco and MGM. The Macau peninsula, the older downtown core, is where SJM's properties and several smaller venues are concentrated10.
The concessions run for a set term, which is why the phrase "Macau concession expiry" comes up so often in news coverage of the territory. The current contracts were signed in 2022 and carry the obligations that shape how each operator behaves, including requirements to open their casinos every day of the year11.
Sands China: The Venetian Macao and the Cotai resorts
Sands China Ltd. owns The Venetian Macao, The Plaza Macao, Sands Cotai Central and The Parisian Macao at Sands Resorts Cotai Strip Macao, plus Sands Macao on the peninsula1. That portfolio makes it the operator most associated with Cotai, the stretch of reclaimed land that Las Vegas Sands turned into a strip of interconnected mega-resorts.

The Venetian Macao is the flagship, and it is the resort most first-time visitors picture when they think of Macau: a vast casino floor under a painted sky, canals with gondolas, and thousands of hotel rooms, all under one roof. The Plaza Macao sits alongside it, and The Parisian adds its own landmark, a half-scale replica of the Eiffel Tower. Sands Cotai Central, later rebranded as The Londoner Macao, sits in the middle of the group, tying the resorts together with walkways so you can move between them without going outside1.
Sands Macao, on the peninsula, is the older sibling. It opened as the first foreign-operated casino of the modern era and remains the place to go if you are staying downtown and want a Sands-run floor without the trip to Cotai1.
What distinguishes Sands China from the other operators is scale. Its Cotai properties are designed as destinations in themselves, with the casino as the anchor and shopping, dining and shows arranged around it. Many casinos have restaurants serving international cuisine, so a visit can easily stretch well past your time at the tables8.
Galaxy Entertainment Group: Galaxy Macau and StarWorld
Galaxy Entertainment Group operates five casinos in Macau2. The two you are most likely to visit are Galaxy Macau and StarWorld.
Galaxy Macau sits on Cotai, at Estrada da Baia de Nossa Senhora da Esperanca, and it is one of the largest single resorts in the territory3. The complex includes the Galaxy Arena, a major events venue that hosts concerts and touring shows, so it is worth checking the events calendar before you go: a visit can coincide with a performance that fills the whole resort12. The resort is built around a huge artificial beach and garden area, which sets it apart from the more urban feel of some rivals.
StarWorld is Galaxy's peninsula property, a tall tower on the waterfront near the Grand Lisboa. It has hosted poker events, including the Asia Poker Tour Macau in its eighth-floor ballroom, so the property has a history with the tournament crowd as well as the mass-market floor13.
Galaxy also runs smaller venues, and one of them, the Waldo Casino, is a satellite property that the company has said it will close (more on the satellites below)14. On the responsible gaming side, Galaxy provides self-exclusion application forms and assistance at its casinos, and it strictly prohibits persons under 21 from entering its casino areas, with clear signage at the entrances stating the restrictions15.
Melco Resorts: City of Dreams, Studio City and the Mocha parlors
Melco Resorts (Macau) Limited holds the license for a distinctive mix of venues: Altira Macau, City of Dreams, Studio City, Casino Oceanus and the Mocha Clubs4. Its concession contract names three licensed casinos: Altira Casino, City of Dreams Casino and Studio City Casino5.
City of Dreams, on Cotai, is Melco's flagship, a multi-hotel complex where the casino floor connects several towers. Studio City, next door, is the entertainment-led resort, known for its figure-eight Ferris wheel and its cinema-themed design. Altira Macau, on Taipa, is the quieter, more upscale property in the group.
The Mocha Clubs are a different animal entirely. These are slot machine parlors, smaller and more casual than the big resorts, aimed at local players and visitors who want a quick session rather than a destination experience. Melco's contract permits seven additional locations beyond its three licensed casinos: Grand Dragon Casino and six Mocha clubs, listed as Mocha Grand Dragon, Mocha Taipa, Mocha Royal, Mocha New Yaohan, Mocha DG and Mocha Inner Harbour5. Slot parlors in Macau typically offer the newest machine games in a comfortable environment, usually with 24-hour coffee shops and dining service8.
Melco is also the operator most affected by the satellite casino wind-down. It has said it will close Grand Dragon Casino and three Mocha clubs, a move expected to be effective by the end of 2025, affecting around 300 local workers by the government's calculation14.
MGM China: MGM Macau and MGM Cotai
MGM China runs two resorts, one on each side of the water. MGM Macau, on the peninsula, is the older property, a single-tower resort with a casino floor that has historically held 423 gaming tables and around 1,200 slot machines16. It offers nine restaurants, so the resort works as a full evening out rather than just a gaming stop.
MGM Cotai opened on February 13, 2018, as an integrated casino, hotel and entertainment resort on the Cotai Strip7. It was built with capacity for up to 500 gaming tables and up to 1,500 slots, though the actual table allocation is determined by the Macau government, which caps how many tables each operator may run6. The resort features approximately 1,500 hotel rooms, and its design, with its "spectacle" atrium of stacked villas, is one of the more striking pieces of architecture in Cotai6.
MGM China offers two loyalty programs: M life, which provides loyalty opportunities similar to MGM Rewards for non-gaming customers, and the Golden Lion Club, a tiered program for gaming-focused customers at MGM Macau and MGM Cotai18. The company also invests heavily in the top end of the market, with premium gaming lounges, stadium-style electronic table game terminals, and villas such as The Mansion, the MGM Cotai Emerald Villa and the MGM Macau Alpha Villa aimed at ultra-high-end customers18.
Like every operator, MGM has had to close when the government ordered it. Its Cotai casino suspended operations until further notice during a 2022 incident, and all casinos were shut during the pandemic closures20.
SJM and Wynn: the other two
SJM is the operator with the deepest local roots. It has operated 17 facilities throughout Macao, the largest count of any concessionaire, spread across the peninsula and Taipa10. Historically, at the end of 2004, SJM ran 13 casinos, nine on the Macau peninsula and four on Taipa island22.

| Gaming equipment | Count |
|---|---|
| VIP gaming tables | 21722 |
| Ordinary gaming tables | 49622 |
| Slot machines | 1,49222 |
| Japanese pinball machines | 18822 |
Its concession contract obliges it to open its casinos every day of each year23. SJM's best-known properties include the Grand Lisboa on the peninsula and the Grand Lisboa Palace on Cotai, and its floors are where you are most likely to encounter the traditional Chinese games alongside baccarat.
Wynn Resorts (Macau) Limited is the sixth operator, running Wynn Macau on the peninsula and Wynn Palace on Cotai. Its concession contract spells out the same around-the-clock obligation: the concessionaire must open the casinos twenty-four hours, without interruption, every day of the year24. Wynn's properties are the most explicitly luxury-led of the six, aimed squarely at premium players and visitors who want a high-end resort experience.
What is happening to the satellite casinos
Satellite casinos are venues that operate under a concessionaire's license but are owned by third parties, typically in hotels that never belonged to the big six. There are 11 satellite casinos in Macau, and they face a December 31 deadline to close or be brought fully under concessionaire ownership14.
The operators have announced their plans in stages. Galaxy is shuttering its Waldo Casino by the deadline, with its workers to be relocated to other properties and given corresponding training. Melco is closing Grand Dragon Casino and three Mocha clubs, effective by the end of 2025, a move the government calculates will impact 300 local workers; Melco has said the employees at these venues will be assigned to work at its other Macau properties14.
If you are planning a visit and have a favorite smaller venue, it is worth checking whether it is on the closure list before you travel. The wind-down is the biggest shake-up of Macau's casino map in a generation, and it will leave the six operators with a more concentrated portfolio of wholly owned resorts14.
Entry rules and self-exclusion
The minimum age to enter any casino in Macau, and to gamble inside one, is 219. The same age limit applies to working in a casino, and staff supervising entry may ask for proof of age and refuse entry to anyone who will not show it26. For comparison, horse racing, football and basketball betting keep a legal participation age of 1827.
Beyond age, the law bars several groups from the gaming floors: public administration workers, including staff of public institutes and security forces, unless authorized by the Chief Executive; persons suffering from a notorious psychic anomaly; and anyone carrying devices intended mainly for recording images or sounds, unless the concessionaire authorizes it28. The older gaming law also lists persons who are drunk or under the influence of drugs, persons carrying weapons or explosives, and off-duty casino employees in their own employer's gaming areas among those barred from gaming rooms29. Concessionaires may also refuse entry or ask anyone to leave whose presence they consider inconvenient, provided they do not discriminate on grounds of sex, race, nationality, residence, language or religion31.
Self-exclusion is available to both residents and tourists. You can apply to be barred from all or part of Macau's casinos, and the Director of the Gaming Inspection and Coordination Bureau (DICJ) may prohibit the person from entering all or some casinos for a maximum period of two years, at your own request or on confirmation of a request by a spouse, parent, child or second-degree relative32. Applications can be made through any Macau casino, in which case DICJ verifies the details and the person must attend the DICJ office in person, or at Responsible Gaming Information Kiosks, which both residents and tourists can use to file a self-exclusion application33. During the exclusion period, the excluded person is prohibited from entering or staying at all or some of the casinos in the Macau SAR35.
Opening hours: 24 hours a day
Macau's casinos are open 24 hours a day8. This is not a market custom; it is a contractual and legal requirement. The gaming law states that each casino must operate continuously 24 hours a day, and the concession contracts repeat it: the concessionaire must open the casinos twenty-four hours, without interruption, every day of the year36. The sector's continuous 24-hour operating schedule is one of its defining features, and it shapes everything from staffing to the coffee shops attached to the slot parlors37.

The only interruptions come when the government orders them. In February 2020, at the start of the pandemic, the Macau government mandated a 15-day closure of all casinos21. In July 2022, casinos and all non-essential businesses were ordered to suspend operations from July 11 to July 18, extended to July 22, and casinos then resumed operations in stages, with no more than 50% of casino staff on site at the same time38. Outside of such extraordinary events, you can walk into any casino in Macau in the middle of the night on a public holiday and find the floor running exactly as it would at noon.
Planning around the operators
Knowing which operator runs which resort makes a visit easier to plan. If you want the biggest, most resort-like experience, head to Cotai and pick from Sands' Venetian and Parisian, Galaxy Macau, Melco's City of Dreams and Studio City, or MGM Cotai. If you are staying on the peninsula, Sands Macao, StarWorld, MGM Macau, SJM's Grand Lisboa and Wynn Macau are all within a short ride of each other, and SJM's network of smaller venues covers the downtown core1.
A few practical points to carry with you:
- Bring ID. Staff at the door can ask anyone who looks under 21 for proof of age, and refusal means no entry26.
- Leave the camera in the bag. Recording devices are barred from casino floors unless the operator allows them26.
- Any casino, any hour. The 24-hour rule applies across all six operators, so late-night play is never a problem36.
- Check the events calendar. Galaxy Arena and the Cotai theaters host touring shows and concerts that can fill resorts on otherwise quiet weekends12.
- Watch the satellite list. If a smaller venue you liked has closed, its staff have generally been relocated to the operator's other properties, so the service culture moves with them14.
