A stack of blue chips sits in the centre. Their matching red chips are hidden face-down around the dial. Tap the blue to reveal its number or icon, then flip reds until you find its pair. Match found — you scored! Unused flips become bonus points, so the quicker the find, the better.
Each blue has a flip limit — and it’s tighter than you’d expect, all based on the Critical Survival Threshold (CST) outlined under A389262 in The On-Line Encyclopedia of Integer Sequences (OEIS®). With 5 pairs you get just 3 flips. Small numbers outside the red chips mark their dial positions — use them to achieve higher scores and claim WR rankings through loop memorization tactics (watch tutorial video ▶). You need a strategy.
LIMBO — If the very first blue runs out of flips unmatched, tap LIMBO to save it and send it to the bottom of the stack for one last chance.
🍀 Lotto — Tap the clover before revealing the blue, then blindly pick a red. Correct = massive bonus. Wrong = costs one flip, nothing more.
Pairs = how many chips. Start small — 2 or 3 pairs to get the feel.
