A focused, offline logic deduction puzzle built around a single clear idea: arrange the operators and light the output.

How it works
Each circuit gives you a fixed chain of HIGH and LOW input signals flowing toward a single output lamp on the right. Between the inputs are empty slots. You are given a tray of logic operators - AND, OR, XOR, NAND - and you place them into the slots. The chain reduces one step at a time, and the output lamp updates the instant anything changes. Fill every slot so that the lamp stays lit and the circuit is solved.

Pure deduction, no decoration
The puzzle is intentionally monochrome. HIGH signals are solid discs and LOW signals are hollow rings. Operators are single abstract glyphs. There are no color hints to lean on and no numbers to stack - only the structure of logic itself. You read the signals, reason about what each operator does, and work out the combination that produces a HIGH output.

Operators
AND: both inputs HIGH produces HIGH.
OR: either input HIGH produces HIGH.
XOR: exactly one input HIGH produces HIGH.
NAND: the inverse of AND - both HIGH produces LOW, everything else HIGH.

Progress that grows with you
Circuits are generated deterministically and scale in difficulty, starting with small two-signal circuits and growing into longer chains with larger trays. Solved circuits are remembered on your device. Reset your progress at any time from settings.

Designed for short sessions
Most circuits resolve in just a few placements, making the game well suited to a spare minute on a commute or a break. The tight feedback loop - place an operator, watch the output respond - keeps the focus on reasoning instead of trial and error.

Interaction
Tap an operator in the tray to pick it up, then tap a slot to place it. Tap a filled slot to return that operator to the tray. The remaining count for each operator is shown beneath the tray so you always know what is left. A short mechanical sound and a lit lamp confirm a correct combination.

Everything stays local
The entire experience runs on your device. There is no account, no sign-in, no network requirement and no data collection. Your sound preference and solved-circuit progress are stored locally and under your control.
