Momo’s Circuit Clues

Trace a complete electrical loop, spot gaps and work out which switches need to close.

How to play

Help Momo investigate six picture circuits. Each has a working battery and a matching working bulb. A closed switch joins its contacts; an open switch leaves a gap. The bulb pictures do not show the result. Trace the whole loop, then choose a prediction or a repair.

A battery, bulb and wires must make a complete loop. An open switch makes a gap. With two switches in the same loop, check both of them.
