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.
