About Cosmic Memory
Memory is a good test of method. The fastest players do not hold more cards in their head than anyone else; they explore in a systematic order, row by row, instead of at random.
Three grid sizes are available: 4×3 to play with a child, 6×4 for a standard round, 8×5 for a real memory workout. The move counter is the score — fewer is better.
How to play
- Click a card to turn it over, then a second one.
- If the two symbols match, the cards stay face up.
- If not, they flip back after a short pause.
- Find every pair in as few moves as you can.

Three ways to get better
- Explore in a fixed order rather than at random — memory latches onto position.
- Always turn an unknown card first, then hunt for its pair.
- On the big grids, memorise in blocks of four squares.
