Memory Match is a browser version of Concentration, a card game that's been played with ordinary decks for decades — flip two cards a turn, and find every matching pair in as few moves as possible.
Pair count scales with your level: 6 pairs near the start, growing past the classic 8 and 10 pair layouts as you climb, up to a 16-pair board at the top end.
Every round you finish is checked against the global Memory Match Top 10 above — no account needed, just a name the first time you place.
