Buzz!: Quiz World, developed by Relentless Software, is the ninth game in the Buzz! series of quiz games. The game is available for PlayStation 3 and PlayStation Portable consoles. It allows users to use question packs purchased for previous Buzz! games as well as supporting user created content and online play. Unlike the previous PSP Buzz!, Buzz: Quiz World (PSP) supports DLC. As with all previous Buzz games the game is available in a game only (Solus) version or in a bundle which includes 4 wireless Buzz! Buzzers and a USB dongle for wireless connectivity (each dongle can connect 4 buzzers to the PlayStation 3).
Quiz World features a mix of old and new round types. For example, one new round hides the answers and then slowly reveals them.
A new feature in Quiz World is player profiling and the host Buzz addressing the player by name, informing them of their abilities and record as a player.
Buzz!: Quiz World also supports PlayStation Home rewards that are rewarded by winning the prize after a round of Buzz!: Quiz World. It supports full game launching for PlayStation Home as well.
Point Builder - This simple round, you earn points on getting correct answers, regardless on how quickly you buzz in.
Fastest Finger - Same as Point Builder, but the player who gets it right the quickest gets the most points.
Stop the Clock - Same as Fastest Finger, but instead of giving the most points to the highest player, you earn the amount of points based on how quickly you buzzed in (counting down from 500)
Pie Fight! - When a question pops up, the answers slowly appear, letter by letter. The play to get it right 1st, gains control of a pie. Buzz in when the crosshairs line up on the player you want to hit, causing them to lose a life; each player having only 2 lives. The last one standing wins.
On the Spot - One player is randomly chosen to answer a tough question. Then, after showing the category for the question, the other players vote on whether the main player will get the answer right. High points if they won't get it, low points if they will. (Definitely! = 100, Probably = 200, Unlikely = 300, No Way! = 400) Then the player wins the points if they are right, and lose the points if they are wrong.
Short Fuse - A bomb will be tossed to a player. They must quickly answer correctly to toss it to the next player, but incorrect answers will force them to keep it, wasting time. If you are holding it when the bomb goes off, the player will lose 300 points.
Over the Edge - A vat of green goo is on the floor. The answers will slowly appear, letter by letter. The player who answers correctly the quickest stays at their spot, but every other player will rise one level. However if the buzzing player gets it wrong, only they will rise one level. Once a player reaches the 5th level, they are tossed into the slime, and eliminated. The last player standing wins the most points.
Boiling Point - In this round, each player answer questions, with a thermometer behind them. Each question they get right raises it one point higher. The 1st player to get it 6 points higher will win the round.
Point Stealer - In this round, the 1st one to get the answer correct will then choose which player they want to steal 300 points from. (However, you can steal from a player with 0 points, but you won't earn any points for doing so)
High Stakes - Before the question, they will show what it is about. Each play will then vote on how much they want to wager on it. (50, 100, 250, 500 points) They win that many point if they get it right, or lose that many if they are wrong.
The Final Countdown - The final round of the game. Each player's points are converted into time, by raising their podium. When each question is asked, their podium will slowly tick down to the floor. The 1st player to answer correctly will slightly raise up, the other correct answers will just stop and not rise, and each wrong answer will drop a bit. After a handful of questions, the podiums will tick down faster and faster. When a player hits the floor, they are eliminated from the game. The last player standing is the winner.
