Circuits: a free puzzle every day
Connect each pair of coloured terminals with wires that fill the whole grid. A new free Circuits puzzle every day.
How to play Circuits
Connect each pair of same-coloured terminals with a wire so that every square is covered. Wires run up, down, left or right and can't cross. No short circuits: a wire may not run alongside (side-on) any other wire or terminal of its own colour. Diagonal contact is fine. Colours can repeat: a wire may join any two terminals of its colour.
Levels
Puzzles come in four levels: Easy, Medium, Hard and Expert. Each day has 4 Easy, 3 Medium and either 2 Hard or 1 Hard and 1 Expert across its 9 puzzles. Circuits isn't on every day's page; when it isn't, you can still play today's Circuits from the link below.
