What it does
Thirty jobs, five chapters
Each chapter teaches one idea: walking, lanes, ordering, turning corners and tolerances. Every room is hand-built.
Unlimited undo
Undo sits under your thumb at all times, labelled with how many moves are left to take back. A jammed crate is called out plainly.
Pars proven by a solver
Every job ships with its optimal move count, proven by a solver, and every job is proven solvable before it ships.
No timers, no ads
No timer, no ad and no move limit. Restart asks twice, so a stray tap never erases a careful solve.
A little workshop
Shift ledger, best moves per job, a clean seal for solving without undo and a master stamp for doing it at par.
Offline and private
No accounts, no ads, no analytics and no network access. Progress is saved automatically and stays on your phone.
A puzzle app with nothing to report
Crates has no accounts, no advertising, no analytics and no network permission. The board saves automatically, so leaving the app never costs you a solve.

Questions
How many puzzles are there?
Thirty hand-built jobs across five chapters, each with a par move count proven by a solver.
Can I get stuck?
You can undo as far back as you need, restart asks for a second tap, and the app points out a jammed crate instead of leaving you to wander a dead board.
Is there a timer or a move limit?
No. There is no timer, no ad and no move limit — only the puzzle.
Does it work offline?
Yes. The app has no network access at all, so it plays the same in airplane mode.
Are the puzzles guaranteed solvable?
Yes. Every job is proven solvable before it ships, and its par is proven by a solver.
Is it free?
Yes. No ads, no in-app purchases and no account.
0.1.4 — refined shift ledger and workbench board, the little packer player character, a plus-shaped D-pad, a first-run foreman guide and synthesised workshop sounds.
