Unlike other Peggle games, in Peggle Deluxe you not only need to earn money to unlock new costumes for your character, but also need to skill up so that you can unlock the special items that are exclusive only to the Deluxe Pack. The game is entirely based on skill, since earning money and health points are secondary goals within the game. The main character, Agent P (rophysometric), must guide his sister, Nicole, across many levels of various difficulty levels as she tries to complete the game. Peggle Deluxe is an addictive, casual puzzle game developed by PopCap Games.
