Puzzle games about electricity.

Electric wires
Rotate wires bulbs and batteries to light all bulbs of the circuit by the current from batteries.

Rotating resistors
Rotate resistors to light all bulbs of the circuit by the current from batteries.

Logic gates
Touch the voltage sources to toggle them between 0 (low voltage) and 1 (high voltage). The level is completed when you glow all the bulbs by high voltage.

Semiconductor diodes
Rotate diodes to light all bulbs of the circuit by the current from batteries.
