Tucked inside a conserved shophouse in the Boat Quay/Circular Road heritage district, Kulnari sits on Singapore’s original riverfront, where merchants once ran warehouses and trading offices along the Singapore River. Today, you’ll climb timeworn stairwells and wander through character-filled rooms that have stood here for decades, before stepping straight into a 1920s mystery of clues, candlelight, and crooked deals. It’s immersive mini-golf, set inside a real slice of the Singapore River story
