About Grid Guardian: Twelve-Station Relay Puzzle
Grid Guardian: Twelve-Station Relay Puzzle is a free online Puzzle game that runs right in your browser. There is nothing to download and no account to create: press Play and you are in. It works on desktop, laptop, tablet and mobile.
A protective-relay coordination puzzle across twelve power stations, from a teaching feeder to a hospital, wind farm, metro, data center and spaceport. Set each breaker's pickup current and time delay so every fault is cleared by the nearest breaker first, normal load never trips anything, and the upstream relay backs up a failed one. Earn three stars without hints and within the sensitivity and delay budgets. A simplified puzzle model, not real engineering guidance.
