How to play
- Tap a part to turn it 90° clockwise and carry the current from the sources on the left.
- Match the number printed on each core. An amplifier adds 1, an attenuator subtracts 1, and an adder sums its two inputs.
- Lock parts you trust. A surge trap that faces a live port blocks every core.
Controls
Click or Space rotates. Right-click, long-press or L locks. Arrows move. Z undoes, Y redoes, H hints.
About this game
Free 30-level logic-circuit campaign. Blue is 1, amber is 2 and purple is 3. Amplifiers, attenuators, one-way diodes, adders and bridges change the current; a live end facing a surge trap shorts the board. Every level is pre-solved, so par is the exact minimum number of turns; three stars need par and no hint.
