The 52-Card Challenge
This is the digital version of the classic boxed matching sets — 52 cards laid out at once, far beyond what working memory can hold. Winning a giant board is about strategy: chunk the grid into zones, sweep systematically on your first pass, and clear one region at a time. Expect your first game to take 10 minutes and your fifth to take half that.
Benchmarks: perfect = 26 moves · excellent < 45 · solid < 60. The move counter and timer keep score, and a flawless run feeds the ✨ Flawless badge.
About the Turtles Theme
Ancient mariners with built-in armour, turtles have been cruising the oceans since before the dinosaurs disappeared. A calm, lovely deck — and proof that slow and steady really does win the game.

How to memorise an animal board
Animal decks reward behaviour-linking. Give each creature a verb — the owl glides, the frog pounces, the crab scuttles sideways — and run the board once as a tiny nature documentary. Actions are far stickier than pictures alone because they recruit the motor memory you use for catching balls and typing passwords.
Group by habitat before you start: sea creatures along one edge, jungle in the middle, farm at the end. When a card hides, you will not remember "somewhere" — you will remember which neighbourhood it lived in, and that narrows twelve choices down to three or four.

Any tips for giant memory boards?
Split the board into quarters and clear one zone at a time. On your first pass, flip systematically (left to right, row by row) to build a mental map instead of flipping randomly.
