Circuit Maze is a fantastic electric circuit based maze game which lets you 'spark' up your logic and sequential reasoning skills (though hopefully without literal sparks!).
Arrange the pieces to create a real circuit and light up the coloured 'Beacons'. These clever circuit-building puzzles are a surprisingly accessible introduction to electrical engineering. (Includes 60 challenges, ranging in difficulty from beginner to expert)
Suitable for a single-player aged 8 and up
