Signal Pips
Toggle a compact grid of signal pips in plus-shaped patterns until every node is lit.
How it works
- Click any pip. It flips on/off, and so do the pips directly above, below, left, and right of it.
- Goal: all lit. Try to light the entire grid in as few moves as possible.
- Local only. The best clear on this browser is stored as a tiny record and never sent to the server.
