Remember one color. Then two. Then five.
Ready when you are
Memory Stack tests sequence recall. Round one shows you a single color; you dial it. Round two shows two colors in sequence; you dial each in order. By round five you’re remembering and reproducing five colors back-to-back, in the order they appeared.
Each color is flashed for a fixed duration, separated by short blanks so you can register them as distinct items. After all the colors have been shown, the slider rig appears with a row of slots — one per color you saw. Pick a slot, dial that color, move to the next, dial that one. The preview swatch updates live for whichever slot is currently selected. You can revisit slots before submitting if you want to refine an earlier guess.
Sequence memory is mostly about chunking. Players who try to remember each color individually drop the middle of the sequence. Players who tag the colors with quick descriptions — “teal, dusty pink, bright yellow” — keep the order intact through the dial phase. The single hardest round is round four: four colors is right at the edge of working memory, and you can’t relax into the “just five” rhythm yet.
Each guess is scored independently using CIEDE2000. Round one is worth up to 10 points; round five is worth up to 50. With 15 total guesses across the five rounds, the perfect run is 150 points. The scoring rewards consistency more than peak performance — you can ace round five and still score badly overall if you sloppy-clicked an early round.
