Sokoban

Sokoban is a free online warehouse puzzle where you push crates onto their marked targets. You can only push, never pull, so one crate shoved into a corner can lock the whole level — every move has to be planned. Play free with no download and no sign-up, on phone or desktop.

How to play

• Move your character with the arrow keys, WASD, or the on-screen pad.
• Walk into a crate (📦) to push it one square in that direction.
• You can push only one crate at a time, and never into a wall or another crate.
• Push every crate onto a target (◎) to clear the level.
• Press U or Undo to take back a move, and R to restart if you get stuck.
• Solve each level and move on through the numbered set.

Before touching a crate, ask where it must finish and which side you need to stand on to push it there — a crate against a wall can only slide along that wall, and a crate in a corner is stuck for good unless the corner is its target. Solve the crates that block the room first, and keep an escape route so you are never trapped behind your own work. When a level tangles, Undo freely and try a different order.
