Wires
Light the bulb — solve the formula! In front of you is a logic circuit of AND, OR, NOT and XOR gates plus the input switches A, B, C... Pick a combination so the output becomes TRUE. The fewer switch flips, the more stars: ★ for a solution, ★★ close to the optimum, ★★★ for the optimum without hints. 100+ hand-crafted levels with growing complexity, a procedurally generated Daily Challenge (deterministic by date — everyone gets the same), hints, undo, achievement tree. A brain workout with no timer and no penalties. Available in 7 languages.
