Because we know just how many fans of the new Ben 10 show are there all over the world, fans who want to play as many fun games with their favorite characters as possible, right now we have decided to add into the Ben 10 Games category a brand new game for everyone to play, entitled Grey Matter Erase, which is a game with images which you have to erase featuring none other than Grey Matter, a really small but really smart at the same time alien from Ben's omnitrix. If you haven't already played erase games in this category, we invite you to learn how they work from this description, and then give the game a go. Using the mouse, you will have to click and hold, and move it to the left and to the right, in order to erase the image of the alien, taken from the show, to reveal another one. You keep erasing the pictures until you have gotten rid of all of them, because then you win the game. Now, we invite you to start playing the game right now, and let the fun begin, only on our amazing website!
