Ichiwa — One unbroken stroke

Trace from dot to dot and cover every line of the figure exactly once — an Euler path puzzle. Every figure is built from a valid stroke first, so a solution always exists. Undo goes back one line only. Ten puzzles.

How to play

  1. Put your finger on a dot and drag to a neighbouring dot. Traced lines change colour
  2. Cover every line exactly once to finish. You cannot take the same line twice
  3. A ringed dot means you have to start there to trace them all. With no rings, any dot works
  4. Hit a dead end? ↶ undoes the last line — press it again to keep stepping back

Keyboard: ↑↓←→ pick a dot / trace a line, Enter start here, Backspace undo one line (undo, then press the same arrow for the next line in that direction), R restart
