Goal
Rotate every pipe until the whole board joins into a single leak-free network fed from the power source in the centre. Every puzzle is solvable — there is nothing to guess.
Pipes
Rotate every pipe until the whole board joins into a single leak-free network fed from the power source in the centre.
How to play
Rules
- Each tile carries a fixed set of pipe stubs; tapping only rotates it, never reshapes it
- The board is solved when no pipe points off the board edge and every pipe meets a matching pipe on its neighbour
- Get there and the whole network lights up, powered from the centre
How to Play
- Tap a tile to rotate it a quarter-turn clockwise
- Pipes wired back to the central source light up, so you can watch the network grow
- Loose ends and pipes that run off the edge stay dim until you turn them into place
- Sure of a tile? Long-press it, or switch on Lock and tap it, to pin it — a pinned tile will not turn until you unpin it
- Keyboard: arrows or WASD move the cursor, Enter or Space rotates, L pins, Z undoes
Tips
- Start at the source in the centre and work outwards, locking in the tiles you are sure of
- A tile on an edge or in a corner can't point off the board — that rules out an orientation straight away
- Terminals (single-pipe ends) have only one correct heading; fix them once their neighbour is settled
Difficulty
The board grows with difficulty: 5×5, 7×7 and 9×9. A bigger grid means a longer network to trace, never guesswork.
