What kind of beast Circuit Puzzle is: rules, tricks and a few tips
The igrasu.ru catalog holds hundreds of games, and this is one people keep coming back to. Here is how it works and how to get the most out of it.

What this game is
Circuit is a rotation puzzle in the spirit of netwalk. A finished board of wires sits on the table, but someone spun almost every tile: the bulbs are dark, yet the battery is still live. Your weapon is a single tap — clicking a tile turns it 90 degrees. Bring the current to every lamp and the circuit closes.
How to play, in short
Energy is computed honestly, not by eye: a wire glows teal with sparks running along it only where two neighboring tiles' connectors face each other. The battery is always powered, and current spreads through every closed branch. One wrong rotation and the far lamp stays dark.
Every board is guaranteed solvable: it is grown from a spanning tree reaching out from the battery, and only then are the tiles scrambled. That tree makes the real solution unique and satisfying. Solve before the timer runs out and the next board is bigger, with a time-left bonus and a COMBO multiplier for fast streaks. Let the lamps stay dark and you lose one of three lives.
