Signal Chain is a sequence memory game on a six-node console. It plays a chain of lit, tuned signals and you repeat the chain back; every round adds one more signal and plays the whole thing slightly faster. Three mistakes end the run, but a mistake only costs you a life: the chain itself is replayed rather than reset, so a run is a long argument with your own short-term memory rather than a single fragile streak.

Tips

Say the numbers to yourself as they play. Six nodes have six tones as well as six colours, and the tones are easier to rehearse than the positions.
From round six, every fourth round is dark: your own presses make a sound but the node does not light. Count in your head rather than watching your hands.
A mistake costs a life but not the chain: the same round replays from the top, so a wrong press early is much cheaper than one at the end.
Speed is scored. Finishing a chain well inside the per-press time limit adds a bonus that grows with the round, so hesitation costs most exactly when the chain is longest.
Pausing replays the round from the beginning when you resume. It is a free second look, but it costs you the speed bonus.
