Tilt a crypt floor and every loose stone slides at once. Fill every gold socket in the same tilt.
Tilt the crypt
A small 6×6 crypt floor holds raised walls, pale loose stones, and gold sockets. You never push a single stone. You tilt the whole floor up, down, left, or right, and every stone slides until it meets a wall, the edge, or another stone.

Stones roll straight over sockets unless something stops them there. Walls become stoppers, and so do the other stones. A stone resting against a wall can hold the next one in exactly the right place.
Fill every socket at once
A board is solved when every gold socket holds a stone after the same tilt. Each board has a tilt limit shown at the top. Run out and the crypt stays sealed, but Undo gives the last tilt back.

Four boards climb from a single stone to three. The first teaches the slide. The last asks three stones to settle into three sockets with one shared set of tilts.
Controls
- Swipe anywhere to tilt the floor in that direction.
- Or tap the four arrows under the board.
- Tap Undo to take back the last tilt, or Restart to reset the board.
- Tap Next when every socket is filled.
