The problem
Pipe-rotation puzzles are easy to generate and easy to make boring: a random board usually has a dozen equally dull solutions and no reason to replay it.
What we built
We handcrafted the levels instead, added junction and limited-rotation tiles so not every tap is free, and scored each level against a par move count, which gives a reason to come back and solve it more cleanly.
Key features
- Rotate straights, corners, 3-way junctions and 4-way crosses to connect the circuit
- Blockers and tiles with a limited number of rotations
- 60 handcrafted levels across three stages, each verified solvable
- One to three stars per level, scored against a par move count
- Undo, reset and hints that suggest the next useful rotation
- A daily challenge picked by the device's local date, offline
- Dark neon theme, switchable sound and haptics, and a reduced-motion option

Challenges and how we handled them
Giving a rotation puzzle a reason to replay
Scoring against par turns a solved board into a better-solved board, which is what the generated version of this genre never offers.
