You Don't Know Jack

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

You Don't Know Jack for PlayStation is currently worth €10.31 loose, €11.45 complete in box, and €27.99 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For You Don't Know Jack, loose is €10.31 and CIB is €11.45 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of You Don't Know Jack is currently worth €10.31 loose, versus €7.85 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
