Connect the terminals of the same color by drawing wires on the grid, but don't let any wires cross!

How to play

The object of a Circuits puzzle is to connect every pair of identical terminals with wires, so that every square on the grid is covered.

Tap and drag from a terminal to start drawing a wire. Drag the end of the wire onto the terminal of the same color and release.



If a wire is in the wrong place, tap it twice to delete it from the grid.

You can also tap a wire once at any point along its length to 'cut' the wire at that point. Tap the wire again at another point to delete just the middle section of the wire (between the two cut points). This can be used when you only want to reposition part of a wire.

Tap and drag from the loose end of a wire to continue drawing that wire. Drag it over another loose end or terminal of the same color to reconnect it.

Wires can turn 90 degrees in any given square. Wires can't double back on themselves within the same square, or overlap with any other wire (including themselves) or any terminal.

Circuits puzzles can be played at different difficulty levels.

In Standard Mode, no wires have been placed on the grid at the start of the puzzle.

In Quick and Super Quick modes, some of the wires have already been placed (in the correct locations) on the grid.


Extra help

If you're stuck on a Circuits puzzle, you can use coins to buy hints.

Hints can be used by tapping on the relevant icon in the status bar area at the top of the screen.

The cost (in coins) to use each hint is printed under its icon.


■ Suggest a move

If you're struggling to see a logical move to enter, use this hint. The game will analyse the current grid and automatically draw a wire in the correct place based on the information available. Wires placed with this hint are locked in place so can't be deleted accidentally.


■ Check for Errors

Use this hint to highlight any incorrectly placed wires. Wires in error will be marked with a red background. Double tap incorrectly placed wires to delete them.
