What is a sand block puzzle?
A sand block puzzle mixes classic block placing with falling sand. Blocks do not stay solid: they break into thousands of grains that slide and pile up. Instead of filling a straight row, you clear sand by linking one color across the whole board. It is the same idea that made sand blocks and sand tetris clips so satisfying to watch.
What Tide Sand adds
You pick blocks from a tray of 3 and drop them where you like, at your own pace. Nothing falls on its own and nothing speeds up. Colors come in sea-glass tones of teal, coral, amber and seafoam, and each clear is a wave that sweeps across the board. Chain clears raise the multiplier up to ×4.
How to play
- Drag a block. Pick one of the 3 tray blocks and let go over the board.
- Watch it flow. The block melts into sand that slides off slopes and settles.
- Link a color. When one color touches both walls in one unbroken path, the tide washes it away.
- Keep room. The run ends only when no tray block fits. You can revive once.
