Remove every bolt and drop every plate by always choosing bolts whose escape line is clear.
A bolt can only leave when no plate above it crosses its exit path. Scan the whole stack before you commit, because removed bolts never come back unless you undo.
Work from the clearly free bolts inward, and use undo freely: there is no penalty. If no bolt can move, the stuck detector will tell you to undo or restart instead of guessing.

Undo reverses your last removed bolt in one tap, so wrong pulls cost you nothing but a moment.
There are 60 levels with rising difficulty, each with a three star time target for replay value.
Yes, every board is generated and verified by the game, so logic always finds a solution.


Unscrewed! is a disassembly puzzle about finding the one move that is actually legal. Each level is a small tower of plates joined by bolts of different colors, and the rule is simple: a bolt can only be removed when the plate sections above it no longer block its path. The first removal is always easy. The fourth is where you start to think three steps ahead, because pulling bolt A may trap bolt B forever, and the undo button is about to become your best friend. The 60 levels form a smooth curve from trivial warm ups to genuine head scratchers, and the three star system rewards not just finishing but finishing fast. Hints reveal one correct bolt when you are truly stuck, and the stuck detector tells you honestly when no legal move remains, so you never waste moves on a lost position. Every board is machine verified to be solvable, which keeps the game fair: logic, not luck, wins here. It runs free in any modern browser, saves your progress locally, and plays perfectly with a mouse or a finger.
