Circuit Connect: Light Up

The room is dark. The wiring is up to you.

Circuit Connect is a quiet logic puzzle about closing electrical circuits. Drag between terminals to run wire, throw the switch, and watch the room light up around you.

── HOW IT PLAYS ──

Every board is a set of coloured terminals — a positive, a negative, and the junctions between them. Your job is to run wire so that current can travel from + to − along every circuit on the board.

Wiring is free-form. Connect whatever you like, in whatever order you like. Nothing buzzes at you for guessing. When you think the board is right, throw the switch — that is the only moment the circuit is judged, and the only way to find out.

Get it right and the lights come on: the dark room fades up around your wiring, and you see the space you have just lit.

── WHAT MAKES IT TRICKY ──

• Colours never mix. Red joins red, blue joins blue.
• White nodes are wildcards — the only legal bridge between two different colours.
• Every terminal on the board has to be part of a circuit. No spare parts.
• Later rooms hold several circuits at once, all of which must close together.

── PLAY YOUR WAY ──

• Drag between nodes, or simply tap one then the other — whichever suits your hands.
• EDIT mode lets you pull out any wire without starting over.
• UNDO and RESET are always there.
• Stuck? Spend stars on a hint: reveal one connection, or complete the board.

── STARS ──

Earn stars for clearing rooms, and collect a bonus every day you come back. Spend them on hints when a board defeats you — or save them and solve it yourself.
