Turn on Bulb

Electricity doesn't flow on its own — in Turn on Bulb, every wire segment needs to be in exactly the right position before anything lights up. The puzzle is deceptively quiet: a grid of tiles, a plug on one end, a bulb on the other, and a tangle of pipe-like connectors sitting at wrong angles between them.

Rotating tiles feels satisfying in a very specific way. One click shifts a piece 90 degrees, and suddenly a dead-end becomes a through-line, or a curve points somewhere useful. The challenge isn't speed — it's spatial reasoning, tracing possible paths in your head before committing.

When the circuit finally closes and the bulb flickers on, there's a small but genuine sense of completion. Later puzzles introduce more complex wire shapes and longer chains, where a single misaligned tile somewhere in the middle can throw off the entire grid.
