Sand Castle Survival

It's a race against the ocean. Dig and build your fort, then survive wave after escalating wave. How long can you keep your toy dry?

How to play

The ocean is at the bottom; your toy figurine sits on a sand mound near the top.
During each build phase, drag on the beach to Dig sand into your bucket, then Pile it back down as walls and mounds. Sand is conserved — you mostly build with what you dig. In a pinch, Get More Sand calls in a fresh bucket, but it costs a big chunk of energy and works only once per build phase.
Holes swallow incoming water; walls deflect it around. Keep your toy's mound tall and ringed.
Press Send the tide when you're ready to unleash the wave — it won't come on its own. You can't reshape sand while the tide is in.
Digging and piling costs ⚡ energy. It refills while you rest. Dug holes retain water after each wave — it evaporates slowly, so plan your terrain.
Each wave is stronger and the build time shorter. Flowing water slowly erodes your sand — light sand fastest, and the backwash drags extra sand out through any gaps.
Score points beyond surviving: stamp 🏰 towers on tall mounds (they earn every wave they stand, but crumble if their mound erodes or floods), keep the wandering 🌟 starfish dry, and drain the tide out through dug channels.
Your toy drowns if water pools around it for too long. ⭐ Score makes the leaderboard.
