Screw Loft: Bolt Sort Puzzle

Unscrew the bolts and take the whole structure of planks apart, piece by piece.

Every bolt flies into a box of its own colour. Three bolts of one colour close the box and a fresh one arrives. There are only three boxes but more colours on the board, so the extra bolts land in the spare tray below. Fill the tray and the level is lost.

A FAIR PUZZLE
Each level is generated together with its solution: the generator plays the board through first and only then assigns colours. Impossible layouts do not exist — if it did not work out, another order would have.

YOU SEE WHAT IS UNDER THE PLANK
A bolt beneath an upper plank cannot be taken, but its colour is visible right away. You can plan instead of guessing.

NO AD SPAM
There are no ads between levels at all. A video plays only when you tap for it — an extra slot, another box, or a rescue from a dead end.

THREE DIFFICULTY MODES
Relaxed for winding down. Normal for balance. Hard puts more colours on the board and takes a spare slot away, so mistakes cost.
