Why card games belong on a memory-games site
Long before apps, a deck of cards was the original brain trainer. Concentration builds visual memory, Higher-or-Lower sharpens probability instincts, and every card game trains focus and working memory in short, satisfying rounds. Ours run entirely in your browser — no signup, nothing to install, and your streaks and personal bests are saved privately on your device. More classics (including Solitaire) are on the way.
