Memory Card Match is the simple pair-matching game you already know, done well. Flip two cards, remember what you saw, and clear the board by matching every pair. Quick rounds, clean visuals, no clutter.
Choose a board size to match your mood — small and fast for a coffee break, larger grids for something more serious. Each completed round is saved with its time and moves, and the stats page shows your best results per board size. Boards can be reshuffled before you start, and you can pause a round if someone needs your attention.
