Plankway

Puzzle archive

Every day there is one new Plankway, the same for everyone. Two days later it moves here. For each puzzle you will find the board, its difficulty, which techniques it needed and a complete walkthrough: every logical step, in the order a careful solver finds them, with links to the strategy guide.

The walkthroughs are written out by Plankway’s own solver, the one that checks that every puzzle has exactly one solution and can be solved without guessing. Use them to see where you got stuck, or to learn a technique from a real puzzle. For an explanation of the labels, see the weekly difficulty.
