Pipes tutorial

Eight short lessons, each with a worked example and four exercises.

Each lesson teaches one technique and then gives you positions where exactly that technique is needed. The pinned tiles are given; you turn the free ones.

1. 1Turn the tilesStartThe goal, the pump, the lamps and how a tile turns.
2. 2Nothing points off the boardStartTiles on the border: their arms must point inside.
3. 3A fixed tile fixes its neighboursStartArms meet arms: follow the chain from every tile you are sure of.
4. 4Two lamps never face each otherStartLamps side by side must point elsewhere.
5. 5No loopsStartPipes already joined may not join a second time.
6. 6No islandsStartA piece that would close up without the pump stays apart.
7. 7What ifStartTry a turn in your head: if it breaks something, it is wrong.
8. 8Wrap aroundStartNo edges: the opposite sides of the board are joined.
