Sandcastle is the ultimate sandbox game. Unlock a variety of tools to gather wet sand, shape towering walls, carve intricate battlements, and engineer elaborate moats designed to withstand or divert the encroaching waves.

No rush, just relax

There are no ticking clocks. Only the slow rhythm of the tide and the warm glow of the sun. Discover secret treasures washed ashore or buried deep into the sand, each adding a touch of personality to your sandy masterpiece.

Physic simulation

Beneath the whimsy lies a unique water and sand physics simulation that brings your creations to life. Sand compacts, crumbles, and holds its shape depending on moisture and pressure, while waves flow, pool, and gently erode your walls just as they would in reality. Carve too thin and a tower may slump; reinforce with damp sand and it stands proud against the tide. The result is a tactile, authentic sand castle crafting experience that feels just like building one on a real beach — sun-warmed, hands-on, and wonderfully satisfying.

Beach layouts

Collect starfishes to unlock different layouts of beach, each with its own character and charm—peaceful atolls ringed by turquoise waters, quiet lagoons with gentle shallows, sweeping sand barriers shaped by the breeze, and winding deltas where little streams meet the sea. Every shoreline offers a fresh canvas, inviting you to build, decorate, and relax in a new seaside setting.
