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.

How to memorise a fantasy board
Fantasy decks want a quest. Cast the board as a story: the dragon guards the crown, the wizard brews the potion, the knight carries the sword. Link each item to the next one until you have a six-beat plot — stories are the oldest memory technology precisely because a chain of causes is easier to hold than a list of objects.
Exploit the archetypes. Fantasy items come in pairs of rivals and partners — sword and shield, wizard and potion, dragon and treasure. Memorise the partnerships instead of the individual cards and half your recall work is done before the board hides.
