How to play & keyboard controls
Connect each pair of matching dots with a continuous line. Lines move horizontally or vertically. Fill every playable square without crossing another line. Drag backwards to shorten a line; drawing across a line trims it. Start on a dot to redraw that color.
Arrow keys move the cursor. Space starts or stops a line. H gives a free hint, U undoes a move, R restarts, N opens the next level, and P opens the previous one. All puzzles and hints are always available.
