One turn to understand the circuit
On the first 3×3 circuit, the mint inlet starts at the upper left and the outlet is at the lower right. Tap the outlined top-right corner once. Its ends turn toward the left and down, completing the path across the top row and down the right side. You win in one rotation; the middle and lower-left tiles do not need to join.
Build a route rather than clicking at random
- Start at IN. Its left-facing port must accept the signal before anything can light up.
- Follow connected mint pipes until the signal stops. Rotate the next corner or straight pipe until both ends line up.
- Work backward from OUT if the route is unclear. OUT must exit to the right, not down through the board.
- Use Hint when you want one tile to focus on, or Reset circuit when you want to rethink the whole route. The map replays completed levels.
A useful example of a broken connection
An east-facing end meets a west-facing end in the neighboring tile. If the next tile points north and south instead, no signal crosses between them. A 90-degree turn can align a straight pipe; a corner may need more turns. Color shows connectivity, while the pipe shapes and accessible button labels explain the actual directions.
