A 1920s switchboard puzzle: patch every socket, light every bulb, and reveal the hidden picture before three wrong plugs drop the line. Step behind a 1920s telephone exchange and patch every line by logic alone. Operator Logic is a nonogram (picture-logic) puzzle dressed as a vintage switchboard console. Every row and column carries a paper clue tag — the exact run of connected plugs along that line — and it's up to you to work out which sockets take a cable and which stay capped. HOW TO OPERATE THE BOARD • Patch Cable plugs a socket in. • Rubber Cap marks one you're certain stays empty. • Match every row and column tag to light its filament bulb. • Light every bulb on the board to patch the call through. MIND THE LINE Three wrong plugs and the line drops — Game Over, tap to try again. Precision matters as much as logic. A BOARD BUILT FROM BRASS AND WOOD GRAIN No flat icons here — every socket, switch, and gauge is rendered like a real piece of 1920s telephone hardware, down to the mechanical click of a plug seating and the warm relay hum when a line connects. The oscilloscope readout keeps you posted on progress in real time. Operator Logic runs entirely on your device — no account, no ads, no tracking, and no internet connection required.
