This game develops memorization skills by placing pairs of cards. Choose from 3 difficulty levels (Easy, Normal, Hard). In each level, a different number of cards (12, 18, 24) the location of the vapor will change. For incorrectly selected cards 5 seconds deducted while you get 10 seconds by placing the pair. When a player finds all pairs of cards, shuffle, and you can play again and try to do better. When the time runs out the game ends. This is the best indicator will be recorded and displayed in the menu for each of the levels. So, the longer you play at the same level, without losing the more points you can earn.
