duk. is a single-player puzzle. You play a little duck crossing a pond of lily pads to reach goose: each lily you leave sinks behind you for good, and one careless path leaves you stranded. Every puzzle is solvable, so the challenge is finding the path, not wondering if one exists.

How to play

The goal: sink every lily pad, then land on goose. The full rules, including move counting, how the pond edge wraps, and what to do when you are stranded, are in the complete how to play guide.
