How it works
The orange start fires once. Arrows travel up to three squares, light every ring they cross, and stop at the first relay. Each relay fires once, in its arrow directions. Arrows can cross empty spaces. Select a placed relay to rotate or move it. Every puzzle has at least one perfect solution.
On a keyboard, Tab to a socket and press Enter to place. Press R to rotate the selected relay. There is no timer and no random result after you commit.
About this prototype & playtest data
Original procedural prototype. No accounts, ads or AI calls. Personal bests, daily attempts and play events stay in this browser. No scores are sent to a server. Clearing browser data resets them. Friend scores are reconstructed locally from their shared layout; they are not server verified.
No global ranking or percentile yet: those need real player data. The daily puzzle changes at midnight UTC. Repeated attempts are marked as practice.
