Dot Weaver

Controls

Drag from a dot to the dot of the same colour. Drawing over a pipe cuts it. Keys: arrows move, Space starts or stops a pipe, U undoes, R resets, H hints, L opens the level list. P or Esc pauses.

How to play Dot Weaver

Every puzzle is a board of empty squares and a few coloured dots. Drag from a dot and lay a pipe, one square at a time, until you reach the other dot of that colour. Pipes cannot cross, except on a bridge. If you draw across a pipe that is already there, you cut it and that colour lifts off the board.

The puzzle is solved when every pair is joined and every square is part of a pipe. A square left blank is not a win, even if all the colours are connected.

Levels, stones and bridges

There are 156 puzzles in 13 packs of 12, each checked to have exactly one solution. They start at 5 by 5 and grow to 10 by 10, and solving four in a pack opens the next. Seven of the packs add a twist. A stone blocks its square: no pipe can pass through it, and it does not need filling. On a bridge, one pipe runs straight across and another runs straight under, and both lanes must be used before the board counts as full.

A move is counted when you touch a new colour. Finish in few moves for more stars. Undo and reset are free.

Tips and tricks

• Join the colours that sit in a corner first. They have fewer ways out.
• If two pipes would have to cross where there is no bridge, one of them is in the wrong corridor. Cut it and try the other side.
• Count the empty squares. A finished board has none.
