What this game is
Memory Match is the classic concentration card game with a math twist. Instead of matching identical pictures, you match each number with a multiplication fact that produces it — 42 with 6×7, 36 with 4×9, and so on. You have to remember where both halves of every pair are hiding, which trains spatial memory and mental multiplication at the same time.
A move is any two cards flipped together. The fewer moves it takes to clear the board, the better — and your best score for each board size is saved on your own device.
How to play
- Choose a board: 6 pairs (24 cards is plenty for a quick round) or 8 pairs (16 cards).
- Flip two cards per move. If one is a number and the other is an expression that produces it, the pair stays open and turns green.
- If they don't match, both cards flip back face-down after a moment — memorize what you saw.
- Clear the board in as few moves as possible.
Scoring
A perfect 8-pair game needs at least 8 moves — you would have to remember everything on the first pass. Good players clear the board in 12–16 moves.
Tips for fewer moves
- Start in a corner path: reveal cards in a consistent order, like reading a book, so positions are easy to recall.
- Think in facts, not numbers: when you see 6×7, immediately file it as "42" so it can pair with the 6×7 card anywhere on the board.
- Don't guess on the last pair: if you know where both cards are, a planned flip saves moves.
Frequently asked questions
Are the multiplication facts always different?
Yes. Every pair uses a distinct product with its own factor pair, so no two cards on the board look the same.
