Sand Drop

Place blocks that collapse into flowing colored sand. A connected color clears when it spans both sides of the board, letting material above fall into potential chain reactions. Periodic tilts change how the piles settle. The run ends when none of the remaining tray shapes fits. Every eight clears the board tilts temporarily, changing the sand's position and sometimes completing a connection without another placement.

Drag a tray block onto the board and let it collapse into sand. Connect one color from wall to wall to clear it, creating room for the remaining blocks.

Mouse/touch: drag a block from the tray and release over a valid position. Invalid drops return it to the tray. No keyboard controls are used.

Blocks cannot rotate. Consider how a placement will flow after landing and how a clear might let another color fall into a chain.
