A compact chain-reaction puzzle where five directional relays must light eight rings from a single spark.

Landing page captured for the 2026-09-08 issue.

Field notes

The puzzle uses five relays as both placement pieces and signal repeaters: each one fires once when struck, sending arrows up to three squares and lighting rings on the way. The page separates a timed daily board from device-local Free Play, while retries and time away remain part of the daily clock. Sharing tools include a copied challenge, a saved result image, and a playtest-log export; leaderboard submission requires a verified account.
