There are really three game variants contained here.
uDraw Pictionary: Ultimate Edition offers what it calls
Pictionary Mode, that is as close to what you've played offline as is possible on a game console.
Pictionary Mania takes advantage of the videogame setting to introduce a custom board with all kinds of special actions tied to categories.
Pictionary Family Fun Mode is really just a subset of Mania, in the sense that you have the ability to completely customize the gameplay experience, right down to the board. The basic gameplay objective is unchanged across all these. Teams (at least two, up to four) of any size can race across the
Pictionary board, and the team to reach the end first wins. On each turn, the person responsible for creating a drawing clue is named the Picturist. That person must quickly draw a visual clue for other teammates to guess, based on a category like "Lunch" or "On The Playground." If a team guesses successfully, play continues for them, or else switches to the next team.
All interaction with the game is done through the tablet. It's a shame there wasn't some Kinect integration, as a value-add for gamers so equipped. Drawing on the uDraw GameTablet is great, but there are times when selecting and navigating menus can be a bit clunky in the heat of the moment. The Pictionary Mania game will be a big hit with traditional players, because of how it expands on the classic game. Mania is basically how you would envision a videogame remix of Pictionary. Normally, categories are just static descriptions that you use as the basis to draw clues. In Mania Mode, categories completely change the play experience, forcing you to draw with dotted lines, artificially capping the amount of ink you can use for your drawing, and even randomly blacking out the screen while you draw. There are about a dozen special conditions like these that come into play during Mania Mode, and you can mix these up as you wish to create your perfect game style for Family Fun Mode. There are also changes to the board that make both the traditional and expanded modes interesting for players who have only done Pictionary offline.
