CogShift

A spatial logic puzzle where you rearrange gears on a grid to transmit power from a source to every target light.

Each puzzle presents a grid with gears of different sizes small, medium, and large scattered across the board. Slide entire rows or columns to reposition the gears, matching adjacent gears of the same size to form a transmission chain from the power source to each target. Special converter pieces bridge connections between different gear sizes, while obstacles force creative rerouting.

Features 6 progressively challenging puzzles that introduce new mechanics one at a time: same-size chains, converter bridges, multiple targets, and blocked cells. Each puzzle includes a par move count for self-improvement tracking.

When your arrangement is ready, press Engine Start to test the connection. Failed targets are highlighted so you can adjust your strategy. Run out of moves and the puzzle ends.
