Gear Keyway Logic Puzzle
Line up the notches — the key does the rest
Tapping any gear rotates it 90 degrees clockwise.
Meshed neighbor gears automatically counter-rotate 90 degrees in the opposite direction.
Align every gear notch horizontally (pointing left or right). When the path opens, the brass key slides through!
In advanced levels, pinned gears never move. Strategically route movements around them.
