Pipe Puzzle: connect the source to the drain

puzzle The water starts in the top-left corner and has to reach the drain in the bottom-right. Rotate the pipe tiles to build a path before the timer hits zero. Free, no download, no sign-up.

How to play

  1. Tap PLAY. The source is the top-left tile and the drain is the bottom-right tile, both locked.
  2. Tap any other tile to rotate it 90 degrees (on a keyboard: arrows to move, Space to rotate).
  3. When the path is complete the water flows through it and the level is cleared, with a bonus for the seconds left.
  4. Run out of time and you lose one of your three lives. Each level has a bigger grid.

Questions

Is every level solvable?

Yes. Each grid is generated around a hidden path from the source to the drain, then the tiles are scrambled.

How does scoring work?

Clearing a level adds points plus a time bonus of 10 points for every second left on the clock.

How big do the grids get?

Level 1 is 7 by 7 and the grid grows by one row and column each level, up to 10 by 10.
