The Hardest Game in the Universe is an online game with pet heads that must reach the circle that moves, and all the puppies must find the exit. It is a game of skill with the special feature that the arrows move all the puppies simultaneously, but not always in the same way. This helps you to practice divided attention, and to use both hemispheres of the brain. Once you get past the first few levels, the puppies will sometimes have to work together, jumping on top of each other to get higher and reach the pink circles (for single use only) and the white circles, through which several pets can escape in this game, one of the most difficult in the world to play online.
