Mogi's Circuit: how to play

A connect-the-wires puzzle in the style of a pipe puzzle. Mogi's lights are out: turn each tile until power runs from the battery to every bulb, using as few turns as you can.

How to play

• Tap a tile to turn it right. Turn it left with right-click, the TURN LEFT tool or the Z key.
• Lit wires glow when they connect back to Mogi's battery.
• The board is done when every bulb is lit and no wire end points at nothing.
• Each turn uses a spark. Run out of sparks and the board short-circuits: a heart is lost and the board resets.
• Sparks left at the end are bonus points.

The five levels

1. Neon City: 4×4: tap to turn
2. Rooftops: 5×5: light every bulb
3. Sewer: 6×6: turn left to save sparks
4. Robot Factory: 7×7: fewer spare sparks
5. Glitch Zone: 8×8 with flickering tiles

Clear the Glitch Zone and the zones loop again on bigger boards with the fewest spare sparks. You have three hearts for the whole run, and the game is the same for everyone each day, so you can compare scores. Press M to turn the sound off or on.

Tips

• Corners and edges have the fewest options: fix them first.
• Work outwards from Mogi's battery, fixing one tile at a time as the lit wire grows.
• Turning left can save two sparks over three right turns.

Questions

Is it like a pipe puzzle?

Yes: the same idea of turning tiles to connect a path, with wires, bulbs and Mogi's battery.

Can every board be solved?

Yes. Every board is built from a full working circuit, then scrambled.

Is it free?

Yes. Five new boards every day, free in your browser.

What are sparks?

Every turn of a tile uses one spark. Each board gives you a few more than the fewest turns needed, and sparks left over are bonus points.
