About this game
You Don't Know Jack marks the series' first official box release in about eight years, after YDKJ6: The Lost Gold .
The series was almost exclusively for the PC, but the new release has been designed with consoles in mind, while retaining the wit and quirky pop-trivia questions of the famous series and web game.

YDKJ supports up to four players, all participating in a fictional gameshow hosted by snarky "Cookie" Masterson.
The show's format is based around asking standard pop culture or general knowledge questions in unconventional ways.
Players are asked to quickly decide if a description matches one item (Dis) or another (Dat), answer science questions framed in hypothetical antics of the cast of Jersey Shore , or decipher Cookie's terrible attempt at ventriloquism through dummy Billy O'Brian (which he pronounces "Dilly O'Drien").
Questions are presented in a multiple-choice format, with four answers mapped to the console's face buttons (or the Wiimote's direction pad).
Players also have the option once each round to "screw" another player if they believe they don't know the correct answer.
Screwed players have five seconds to pick an answer.
If they get it right, they get a point bonus, and the "screwer" has points taken away.
After ten questions, divided into two rounds, players take on the "Jack Attack" - where the player who rings in first when two matching words cross the screen takes the points.
New for the 2011 version of YDKJ is the ability for all players to answer every question.
Previously, the first player to "ring in" was the only to answer - in the new version, each player answers with the speed of their answer dictating a point bonus.
Unlike older versions, questions are not randomized.
Instead, the game is divided into 70 fixed episodes of the show, with support for more to be downloaded as DLC (for the PS3 and Xbox 360).
Each episode is sponsored by a fictional company/product, which inspires the "Wrong Answer of the Game." This question is, as th
About PlayStation
The original PlayStation (1994) brought CD-based gaming and 3D graphics to the mainstream, ending Nintendo's console dominance of the previous two generations. It's now firmly in "retro collecting" territory: original jewel cases with intact manuals command a real premium over disc-only copies, and several RPGs from its later years (when Sony deliberately courted the genre) are among the most expensive commonly-collected games from the era.
Gamevaro tracks You Don't Know Jack [Demo CD] for PlayStation with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding You Don't Know Jack [Demo CD] to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This PS1 release dates back to 1999.
