Sokoban is the crate-pushing puzzle that has ended more planning sessions than any spreadsheet: push every crate onto a goal square, and remember you can push but never pull.
Nothing listed in the connect popup: the calculator has to be plugged in and switched on to appear. Wake it up, check the USB cable (charge-only cables won't work), or move to a different port. Close any other tab that's using the calculator.

Controls
- Arrows move you. Walk into a crate to push it. You can't pull.
- ENTER undoes your last move. Keep pressing it to go back as far as you like.
- DEL restarts the level.
- CLEAR leaves the level and goes back to the level grid. Press it there to go back to the difficulty screen, and once more to quit.
- On the difficulty screen, left / right arrows pick EASY, MEDIUM, HARD or EXPERT and ENTER opens the level grid.
- On the level grid, arrows pick a level and ENTER plays it.
- After you solve a level, ENTER goes to the next one and any arrow or CLEAR goes back to the level grid.
96 levels, honestly graded
The pack has 24 levels each at EASY, MEDIUM, HARD, and EXPERT, and every level carries a par: the fewest pushes that can solve it. EASY levels par around 4 pushes; EXPERT levels par around 24 and interlock like a watch.
Chasing par
Par is shown live while you play, and finishing rates your solution OPTIMAL, GREAT, or GOOD. The level-select grid remembers you: gray for unsolved, green for solved, gold for solved at par. Turning the whole grid gold is a long-term project, and the calculator saves your best push count per level.
Undo
Unlimited undo means a wrong push is a lesson, not a restart.
