Custom: × any rectangle up to 64 cells (e.g. 4×12) — smaller levels count via wall padding

Exit location (canonical, up to symmetry)

Movable blocks ≤ Holes ≤ Walls ≥ Solution must not push a block over the exit Only solver-verified levels (default also includes "claimed proven") Also show unproven & proposed levels

Submit a level

Paste a Pathology level code (rows of tiles, one row per line; tiles 0-9 A-J, single exit, any rectangle up to 64 cells). Most levels are verified optimally; if one is beyond the solver, you'll be asked for your best solution and it is stored as an unverified claim. A level is accepted if no stored level matches or beats it in every way — including smaller levels padded with edge walls.

Don't submit, just show me the stepcount.

Runs the strongest solver on your level and reports the optimal move count — nothing is stored.

Submit to The Playground

Playground levels are kept for their own sake. They are still solved and still checked against the records, so one that beats a record becomes one — but a level that does not is kept anyway instead of being turned away, and it stays even if something later supersedes it.
