HALL OF FAME
A tribute to people whose related scientific works inspired this game
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. With 9 pairs, just 6. 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.
The cycle and the row — the art and heart of the game
The icon on each red chip also encodes its number — Zebra has 4 legs, Hand has 5 fingers, Glasses have 2 lenses. Use this. When you flip a red, its value tells you where to look next. Blue is Zebra (4) → flip position 4, find Hand (5) → flip position 5, find Glasses (2) → flip position 2, find Zebra — matched! You’ve traced the cycle 4→5→2→4. Now you know exactly where 5 and 2 live for all future blues. Loops controls how long or short these cycles are — mastering them is mastering the game.
While the Rower mostly replays a linear sequence from the start to locate each value — often pointing chip by chip — the Cycler’s associative map usually delivers the answer in a single mental step, not unlike “go two blocks, turn left, continue straight before making a right…” or even “go straight, you’ll see it” vs. “it’s next to the obelisk.” On another level, both benefit from the brain’s visual memory, just like in a classic picture matching game.
Following a row strategy can also get you pretty high scores, especially when combined with blind-guess Lotto, Limbo and pinning. But all those tools are available to the Cycler too, along with some sly shortcut and bumphole tactics. And as pairs grow, the Rower starts to sweat…
The extras
🍀 Lotto — Tap the clover before revealing the blue, then blindly pick a red. Correct = massive bonus. Wrong = costs one flip, nothing more.
📌 Pin — After flipping a red, tap the pin to rotate the dial so that chip lands on its own position. A guaranteed future find.
👁 Eye — Tap to peek at all reds at once. Tap again to hide them. One use per game.
☀️ / 🌙 Sun & Moon — Toggle between dark Moon mode and bright Sunny mode for outdoor play. Safe to switch any time, even mid-game.
❓ Tips — A long collection of short one-liners to help you master the game. Tap to open.
Pairs = how many chips. Start small.
