Memory Pairs

Memory Pairs is a concentration game with twenty face-down cards hiding ten pairs of symbols. Turn over two cards at a time: if they match they stay face up, and if they do not they flip back after a moment.

The challenge is remembering where everything was. Try to clear the board in as few moves as possible — a careful player can finish in under twenty. It is a good short workout for your memory and works well for younger players too.

Find all ten pairs. A move is counted each time you turn over a second card. Fewer moves is better.
