Crunch Locked — a foldable ruler puzzle
Foldable rulers sit on the playfield. Tap a free segment and it rotates 90 degrees, connecting to the next one. That way, the ruler folds up step by step. When only one visible piece is left, it disappears and you clear the level.
The challenge is in the order you make your moves. Dark segments are locked in place and won’t move. The rulers get in each other’s way: a rotated piece can block a neighboring one. So first look for a ruler that won’t hit anything else. A similar idea shows up in Nuts Bolts Puzzle, where it also matters which part you remove first.
