How to play Dot Plumber

1. Each colour has two dots. Press on one and drag to draw a pipe, square by square, to the other.
2. Pipes can’t cross or go through another colour’s dot. Drawing over another pipe cuts it.
3. Drag back along your pipe to undo, or press on a dot to start that colour again.
4. A board is solved when every pair is joined and every square is filled.
5. On difficulty 5, three boards: 5×5 with four pairs, 5×5 with five, then 6×6 with seven. 54 seconds for all of them.
6. You start on difficulty 3 of 10. Clear a difficulty to unlock the next: difficulties 7–10 have four boards in the same 54 seconds. Difficulties 1–4 have fewer or smaller boards (a 4×4 warm-up, and no 6×6 on difficulties 1–3). Pick any unlocked difficulty with the arrows on the start card.

Tips

• Start with pairs that sit next to each other or along an edge. Their route is usually obvious.
• Pipes that hug the walls leave the middle free for the others.
• If every pair is joined but a square is empty, one of the pipes has to take the long way round.
• Everyone gets the same boards all day, and new ones at midnight UTC. “Practice a new layout” deals fresh boards any time, off the leaderboard.
