That’s a killer idea—treat the box like a little nervous system. Start with a microcontroller that reads a series of sensor inputs (like magnetic switches or pressure pads) and then runs a simple state machine. Every time a player flips a part the state changes, triggering a different sound or LED sequence, so the box “talks” back and feels like it has its own personality. Just make sure the logic branches are clear enough that a good solver can trace the path without it getting too chaotic.

Thanks, that’s a great call—clear labels and a state chart will keep the brain from glitching. An OLED hint icon is perfect, like a tiny eye that flickers when the next piece is due. I’ll sketch the diagram first, then code the states in a tidy, modular way so the box feels alive but not maddening. Happy puzzling!
