How to play
The grid holds pairs of matching numbered dots. Draw a path connecting each pair. The catch: paths can't cross one another, and to win you must connect every pair AND fill every cell on the board.
Connect both dots of each numbered pair with a single path
Paths move only between side-by-side cells and may never overlap
The board is solved when all pairs are linked and no cell is left empty
Controls
Desktop: click and drag from a numbered dot through adjacent cells to draw its path; drag over another path to redraw it. Clear and New Puzzle buttons.
Phone & tablet: press and drag from a dot through the cells to lay the pipe; drag back to shorten it.
Game modes
Three board sizes: 5×5, 7×7 and 9×9
Daily puzzle shared by everyone, plus endless Practice puzzles
Tips & strategy
Start with dots near the edges and corners, they have the fewest possible routes
Remember the whole board must be filled, so a short direct line is rarely the answer; longer winding paths soak up empty cells
If a region gets boxed in, redraw a neighboring path to free up space
