How to play Sand Tetris
Sand Tetris is the classic falling block game with a twist: every block turns into sand when it lands. The sand slides, piles up and fills gaps on its own, so every drop changes the board.
To clear, connect one color from the left wall to the right wall. It does not have to be a straight line. As long as the same color touches all the way across, the whole patch disappears. Bigger patches score more, and the game speeds up as your level goes up.
The game ends when the sand reaches the top.

Tips
- Spread colors sideways. A clear only needs a thin path of one color across the board.
- Let gravity help. When a patch clears, the sand above falls and can complete new paths for bonus clears.
- Keep the middle low. Pieces drop from the center, so a tall middle ends the game fast.

What is Sand Tetris?
Sand Tetris is a falling block puzzle where every block breaks into grains of sand when it lands. Instead of filling a row, you clear sand by connecting one color all the way from the left wall to the right wall.
How do you clear lines in Sand Tetris?
Any patch of a single color that touches both the left and right walls clears instantly. The grains only need to touch each other, so the path can bend and climb across the board.
