Lithos

Drop, rotate, and stack falling 3D blocks into a tabletop shaft. Fill a horizontal layer to clear it and keep stacking before the shaft reaches the top.

Pieces and the shaft

Pieces fall one at a time into a 5×5×10 vertical shaft. Each layer is colored by depth, so the stack reads at a glance.

Controllers or hand tracking

• Controllers — right joystick moves the piece, left joystick rotates it, click either thumbstick to drop.
• Hand tracking — Quest microgestures: swipe with the right thumb to move, swipe with the left thumb to rotate, tap a thumb to drop.

Three difficulties

Easy, Medium, and Hard change the falling speed, the score multiplier, and which pieces show up — small, simple shapes on Easy; five-cube pentacubes added on Hard.

Tutorial and leaderboard

A three-step tutorial covers movement, rotation, and the drop. A global leaderboard tracks top scores between sessions.

Designed for stationary play. No locomotion, no forced camera moves. A clean, minimal puzzle that fits a quick break or a longer run.
