How to play & keyboard
Tap a track to rotate it clockwise. Each quarter-turn spends one turn; a straight track switches between its two distinct orientations. Dashed tracks marked □ are fixed. Empty squares cannot carry the pulse.
Run is free. A pulse follows the connected openings. If it stops, the highlighted square tells you why. Undo refunds the last turn; Reset restores this puzzle. You can choose any level, in any order.
Use ← ↑ → ↓ to move around the board, Enter or Space to rotate. R runs, U undoes and X resets. Sound is optional and starts off. Progress lasts only for this open page.
