LiveWire
300 tuned levels
A twelve-level teaching sequence, then a campaign that widens from a 5×3 board to 14×9 across Power Specialist, Circuit Expert and LiveWire Legend tiers. Every level is generated against a verified solution — nothing is impossible.
Android · Free to play
Build the circuit, light the load.
Drag wires, diodes and transistors onto the board until current reaches every lamp. Three hundred hand-tuned levels that teach real electronics without a single word of theory.

How it plays
Power has to go somewhere
Every board starts with its batteries and loads already mounted. The parts bin holds exactly the pieces the solution needs — nothing spare. Drag them onto open cells, tap to rotate, then close the circuit and watch the current run. Point a diode the wrong way and nothing lights. That is the lesson.

Why LiveWire
A puzzle box that happens to teach electronics
No tutorials to sit through, no energy timers, no wall you have to pay past. Just a board, a bin of parts, and a circuit that either runs or doesn't.
Components that behave
Diodes conduct one way. Resistors protect LEDs. Transistors need a yellow control signal on the base. Buck and boost converters halve and double voltage. The simulation enforces all of it.
Ordered checkpoints
Later boards mark cells your current has to reach, in sequence. A route that lights the lamp but skips checkpoint two is a route you have to think about again.
Rated by complexity
Each puzzle carries a score computed from its turns, blockers, branches, voltage rules and specialist parts. Levels are ordered by that rating, so difficulty climbs steadily instead of lurching.
No account, no server
There is no sign-up, no profile and no cloud save. Your progress is a number stored on your own device. Uninstalling the app removes it completely.
Free, with optional ads
The whole campaign is free and there is nothing to buy. A short rewarded video is offered between levels — always optional. Players under 13 see non-personalised ads only, and no advertising ID is sent for them.
Ready when you are
Close the circuit
LiveWire is free on Google Play. It needs no account, works offline, and starts you on a three-cell board that anyone can solve in about ten seconds.
