Twisted Wizard

Twisted Wizard is one of Greg's video games. He was going to get it one Christmas, but his present was mixed up with a present for the 'Giving Guy', so his mom bought him a new copy of Twisted Wizard. Instead of getting Twisted Wizard, he got a sweater. According to the online version, his mom bought him a replacement copy, but only after Greg wrote all his thank you notes. It is a game using a machine similar to a Sony PlayStation 2, and is described as being "impossible to save" in the online version of the first book. However, in the movie, it is clearly a Nintendo Wii game. In the movie it is obviously a racing game, seems to have some form of currency(shown in the bottom-left corner of the players' screens), and you are able to attack your opponent(only one attack is shown, it looks like some kind of fire).

Greg always beats Rowley in Twisted Wizard, with the exception of Dog Days, where Rowley injured Greg and hindered his ability to play, thus beating him and winning the "grand prize" of a large box of chocolate-covered raisins.
