Lumio is a puzzle game about how electronics think. Each level is a blueprint: lamps, switches, and empty slots for logic gates. Drop in the right gates, run the wires, flip the inputs — and the circuit comes alive: lights glow, signals race, counters tick. It all starts with a single lamp and a NOT gate. Then come AND, OR, and XOR, the laws of logic and truth tables, adders, flip-flops and memory, counters, registers, and buses.
