Based on the TV series, iCarly is about a girl named Carly Shay who creates her own web show called iCarly with her best friends Sam and Freddie. Carly's videos that are uploaded on the iCarly site are being deleted, and it turns out that Nevel has taken down their website. So Carly and her friends have to get their website back by playing 10 minigames, presented as show skits, and they allow players to work with the characters through new adventures. The iCreate mode lets players add their own touches to the webisodes by swapping out props, characters, color schemes, audio, intros, outros and other elements. Up to four players can either compete or cooperate to complete the skits and earn Web-Creds, which can then be used to purchase new items, props, accessories and locations from in-game websites.
The Wii version of the game allows for up to four players at once.
