The objective is to find all the pairs in the shortest possible time. When a card is turned up twice or more, it will cost time (penalty).
The number of pairs for each game can be chosen, it can be between 5 and 35.
There are three decks styles:
1) Flags: Normal mode because you can memorize forms or colours.
2) Numbers: Hard mode where each card is a number
3) Dots: Each card has 3 dots, so you have to memorize the exact position of all of them.
The five best times for each combination of number of pairs and deck types will be saved.
