Sandtrix falling-sand puzzle
Left and right arrows or A and D move the piece. Up arrow, X or W rotates clockwise; Z rotates counter-clockwise. Hold the down arrow or S to drop faster, press Space to drop at once, and C to hold a piece. P or Escape pauses; Enter starts. On touch screens tap the board to rotate, drag sideways to move, flick down to drop, or use the pad.
01 · HOW IT WORKS
- Every piece crumbles into coloured sand the moment it locks.
- Sand clears when one colour connects the left wall to the right wall. Grains must touch side to side or top to bottom; a full row on its own does nothing.
- If a clear lets the sand above fall into a new connection before it settles, that is a chain — each link multiplies the points, up to ×8. A connection made only of fresh sand from a new piece starts again at ×1.
- Every 4 clears raises the level, and the pieces fall faster.
- The game ends when a new piece has no room to appear, even after a short wait for the sand to slump.
