Watch the cells light up in order, then repeat the sequence. It grows by one each round.
No account. No tracking. Your results stay with you.
Watch, then repeat.
Cells light up one after another. Repeat the order. Each round adds one step. Three lives.
Needs to see cells light up (each also shows a ring and number). Answer by click, tap or keys 1–9.
Cells on a 3×3 grid light up one after another (each lit cell also shows a ring, so the cue isn't colour alone). Repeat the order by selecting the cells — click, tap, or keys 1–9 laid out like a phone keypad.
The first round has two steps. Each success adds one more step to the end of the same sequence. A mistake costs a life and replays the same length with a brand-new random sequence. You have three lives; the run ends when they're gone (or at 30 steps).
score = longest sequence reproduced correctly
Sequences are cryptographically random with no back-to-back repeats. Each step is shown for 550 ms with a 200 ms gap.
