Choose between a 16 or 36 card game. The cards a shuffled with each game.
HOW TO PLAY. All the cards on the grid begin face down. Tap a card to turn it over. Try to find the second card that matches the first.
If the second card does not match, both cards return to a face down position. If they do match, the cards remain as they are.
Try to match all the cards on the grid in the fewest steps possible. The trick is to use your memory to remember the cards even when they are turned back over.
This card matching game helps train short-term memory. This type of memory is very important for problems solving and other tasks where you need to hold several pieces of information in mind at one time.
Research has shown that most people can only hold about 5 to 9 items in short term memory. Memory tricks such as chunking can greatly extend this range, however.
The limit of human short-term memory is why phone numbers, credit card numbers, and other long sequences of numbers are often broken into smaller groups of 3 or 4 digits.
