CIPHER

Goal: 8 nodes ring a central hub. Each round they flash a sequence — shape and tone together, never color alone. Tap the same nodes back in the same order.

Growing chain: Round 1 starts at length 3. Every clean round adds one more node and speeds the flashes up a little — the chain never resets, only grows.

Grace shields ⛊: You earn one every 5 rounds cleared. A shield absorbs a single wrong tap or a missed tap window — the sequence replays, no run-ending. Your first slip in rounds 1-2 is always forgiven for free.

Combo: Clean rounds (no shield spent) build a streak that multiplies your score. Spending a shield resets the streak — but never ends the run.

Later twists: From round 6, two nodes sometimes flash together — tap them back in either order. From round 10, a silent, duller "ghost" flash may sneak into the sequence — ignore it, it isn't part of the chain.

Run over: a wrong tap or a timed-out tap window with no shield left. You'll see exactly where the chain broke before the score screen.

Daily Sequence: one seed per day, identical worldwide — same chain, same growing tempo, compare your best round with everyone playing today.
