Pipe Connect

The water tank in the grid is the source. Every other tile holds a pipe piece — straight, bend, T-junction or a dead-end drain. Rotate the tiles so that the pipes form one connected network that carries water from the source to every drain, with no pipe left open-ended.

Controls

• Tap / click a tile to rotate it clockwise. Right-click (or Shift+click) rotates counter-clockwise.
• Keyboard: arrow keys move the highlight, Space / Enter rotates, Z rotates back.
• Tiles that already carry water are tinted blue so you can see how far the flow reaches.

Puzzles

Choose a size from 5×5 up to 10×10. Every puzzle is generated from a random tree of pipes, so it is always solvable. Your move count is compared to the minimum number of rotations needed; best results are saved per size. An unfinished puzzle is saved automatically.

Tips

Start at the edges and corners: a pipe on the border can't point outwards, which often leaves only one possible rotation. Drains (dead ends) can't touch each other, and straight pipes have just two distinct orientations.
