View the Next EventRWS Muay Thai, officially known as Rajadamnern World Series, is the flagship Saturday-night event at Rajadamnern Stadium in Bangkok.
Launched in 2022, RWS combines full-rules Muay Thai with open scoring, shorter regular bouts and a contemporary live production. The result is a professional Muay Thai event that remains true to the sport while being easy for new audiences to follow.
A typical RWS event features seven bouts involving established Thai names, international competitors and emerging talent.
Most regular RWS bouts are contested over three rounds, while selected championship contests may run for five rounds.
The judges’ scores are displayed after every round. This allows guests to see who is leading and understand how each bout is developing before the next round begins.
Open scoring also changes the tactics inside the ring. A competitor who is behind may need to take more risks, while someone leading can adjust their approach to protect the advantage.
RWS uses full Muay Thai rules, including punches, kicks, knees, elbows and clinching.
RWS has created a distinctive Saturday-night format while keeping professional Muay Thai at the centre of the event.
The judges’ scores are shown after every round, making each bout easier to follow.
RWS regularly brings together leading names from Thailand and competitors from across the world.
Rajadamnern titles and rankings remain an important part of the series.
Lighting, entrances, screens and the stadium’s dome projection create a different atmosphere from Rajadamnern’s more traditional weekly events.
Every RWS Muay Thai event takes place at Rajadamnern Stadium on Ratchadamnoen Nok Road in central Bangkok.
Opened in 1945, Rajadamnern was the world’s first purpose-built Muay Thai stadium. It remains one of the sport’s most important venues and continues to host professional events throughout the week.
For RWS, the stadium combines its historic setting with modern lighting, screens and arena production. The ring sits at the centre of the venue, with tiered seating surrounding it on every side.
RWS is suitable for experienced Muay Thai followers and first-time guests.
The open-scoring system makes each bout easy to understand, while the stadium screens and announcements help guests follow the event throughout the evening.
RWS uses full Muay Thai rules, but its format differs from the traditional events held at Rajadamnern on other nights of the week.
Traditional stadium cards often place greater emphasis on five-round contests and slower tactical development. RWS generally uses three-round regular bouts, visible scoring and a more international production style.
The techniques and competitive standards remain Muay Thai. The difference is how the event is structured and presented.
For first-time guests, RWS is one of the easiest professional Muay Thai events in Bangkok to follow.
RWS played an important role in a major moment in Rajadamnern Stadium’s history.
In August 2022, the stadium hosted a women’s bout for the first time. Women’s contests and championship competition have remained part of RWS since then.
This helped open a new chapter at Rajadamnern and gave leading female competitors a place on one of Muay Thai’s most recognised stages.
Yes. RWS events are open to Thai and international guests, and no previous knowledge of Muay Thai is required.
The open scoring, clear event structure and modern production make RWS particularly accessible for visitors attending Muay Thai for the first time.
Tickets can be booked online before the event. Advance booking is recommended because Ringside, Club Class and LEO Section can sell out before Saturday, particularly for championship cards and major events.
