Starstone Trace

Moon constellation: a new ordered-star, six-turn solution. Live star/turn/ink counters, reachable-neighbor markers, and tap-to-retract reduce blind checking.

Draw one non-crossing orthogonal line. Visit both stars and end at END with exactly four turns. Check validates all three rules.

Tap or click the controls. Keyboard: Tab and Enter/Space operate every button; arrows/WASD move where available, R restarts, Z undoes calm puzzles.

Mistakes remain revisable. Unlimited undo and restart recover deadlocks.
