Test your skills in memory with the Ben 10 Memory game featuring aliens from the Ben 10 universe! Click on the cards to turn it up and click another one to see if it is a pair and if they aren't the same alien then they will turn back again for you to find the matching aliens. You have 1000 starting points and each new pair that you make is worth 100 more points. Each wrong pairing will deduct 10 points from your score though so be careful. You can choose from three difficulties that will change the number of cards in the level from 12 aliens to 30.
