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 Sherlock Holmes Theme
Conan Doyle's original Sherlock Holmes stories are in the public domain, so we're free to celebrate the great detective properly. Deerstalkers, magnifying glasses, dossiers and the fog of Victorian London await.
