"Gimmicks" are like the bonus items you can get in a game like Mario Party, or whatever. They're used to infuriate other users and push you ahead. There are four existing gimmicks, and they are as follows:

STEAL - The most common and (probably useful) gimmick. You can use this to steal the points for a question, even if someone has already guessed correctly. The points for a question become permenantly the owner's after the day's round ends. You cannot use a steal on a bonus question.

THUMP - You use a thump on someone to cause them to LOSE a point for a correct answer, rather than gain. Beware - if they guess incorrectly, and you use a thump before I update, the thump will backfire and YOU will lose one of your points! This results in a net loss of points; both you and the thumped will lose a point. Don't try to edit your post after someone thumps you- if you're thumped, and you edit your post for any reason, the thump will never backfire.

JUXTAPOSE - This is an extremely rare gimmick. By using a juxtapose, you can steal ALL OF THE POINTS of anybody at least five ranks below you. Due to the extreme power of this gimmick, it is very unwieldly; you'll have to use it on someone who's sleeping (That is, hasn't made an attempt at a guess in at least 2 weeks) Oh, and you can never use it on me.

TIME GEM - By far the shiniest gimmick. If you get one, you can use it at the same time you answer a question. On the next question, your guess will get instant priority. If you have multiple time gems, you can "chain" them to answer as many questions in a row as time gems you have. If you answer it wrong, or don't answer in twenty-four hours, the chain automatically breaks, and you lose the last gem you were going to use, but didn't.
