Singapore has ambitious developments planned for Sentosa, the government’s iconic holiday island that already hosts one of the globe’s largest casino resorts.

The Sentosa Development Corporation (SDC) has announced an extensive long-term redevelopment plan for the resort and theme park destination located off Singapore’s southern coast. This ambitious 20-year project, spearheaded by the Ministry of Trade and Industry, is titled “Your Island. Reimagined.”

The government reveals that this initiative prominently features the integration of the adjacent 49-acre Brani Island, enhancing Sentosa’s reach and overall appeal as a premier holiday destination.

According to the SDC’s announcement, new attractions in Sentosa will encompass the Imbiah Canopy, a state-of-the-art hilltop retreat at Mount Imbiah, featuring diverse dining, retail, and event venues, as well as the Sensorium, a beachfront lifestyle hub designed with sustainability in mind.

This multistage redevelopment of Sentosa aims to improve connectivity with the main island, refresh its beaches and coastlines, and emphasize eco-friendliness.

Casino Enhancements and Super Nintendo Theme Park

Resorts World Sentosa serves as the main anchor for Sentosa, being the integrated resort owned by Malaysia-based Genting that made its debut in January 2010.

In 2023, RW Sentosa unveiled plans for an extensive renovation and expansion exceeding $5 billion. This investment significantly overshoots the government’s stipulated requirement of around $3 billion, which was put in place to maintain its competitive position alongside Marina Bay Sands for at least another decade.

By 2030, Resorts World Sentosa is set to unveil two new luxury hotels with 700 high-end rooms and a four-story retail hub. The existing S.E.A. Aquarium will undergo major renovations to become the Singapore Oceanarium, and the highly anticipated Super Nintendo World will add to the excitement as a new theme park attraction, following Illumination’s Minion Land.

Super Nintendo World will mark the first of its kind in Southeast Asia, featuring immersive rides such as Mario Kart: Bowser’s Challenge, a pioneering attraction blending real-life experiences with augmented reality.

The ambitious $5.3 billion expansion project at Resorts World is on track for completion in 2030.

Officials from the Singaporean government are optimistic that the next phase of the Greater Sentosa Master Plan will double the current visitor numbers. Last year, Sentosa attracted around 16 million guests.

“For over five decades, Sentosa has welcomed countless generations of Singaporeans and global visitors, evolving into a cherished place filled with memories and beloved by many. In many respects, it represents the Singapore brand on a global scale,” remarked Thien Kwee Eng, CEO of Sentosa Development Corporation.

“The Greater Sentosa Master Plan represents the most transformative chapter in our history. We remain dedicated to honoring the island’s essence and identity while crafting next-level world-class experiences. Before anything is constructed, we want to share this vision transparently and encourage Singaporeans to contribute and co-create,” Kwee Eng concluded.

Sands Competes

The casino duopoly in Singapore is primarily led by Sands, which captured an 87% share of the gaming market in 2025. Over the years, Resorts World Sentosa has seen its market presence gradually decline, while Sands has fortified its standing.

Nonetheless, both establishments are tremendously profitable. In 2025, RW Sentosa reported a net operating profit of $308.2 million.
