Explanations of Blitz, Rapid, Bughouse and so on?

Please, is there somewhere on this site that explains the difference between the various tournaments, e.g. between 5 minute blitz and 5 minute rapid? Thanks

Thanks for that Martin. You're so helpful and the best thing on this site, probably. But you and others will have to dumb down a little to talk to me. I don't want to know about variants cos straight chess is difficult enough for me. I just wanted to know about the differences between Rapid / Bullet / Blitz / Arena. Is there a 101 somewhere?

Rapid is a time control where you get more than 10 minutes per side as your initial time. Adding increments, that gives you enough time to think carefully about your moves. It's important for improving as, (this is what I am told) it helps you to develop your chess vision, etc.

Bullet is another time control where you get limited time (like 2 minutes per side) with short increments initially. You will have to think fast and play fast, otherwise you will likely lose on time. Since you don't think much in a bullet game, blunders and mistakes are prevalent. 

Blitz comes between rapid and bullet. It varies from 3 minutes to 10 minutes per side. You have adequate time to think in the beginning. As the game progresses, it changes into a bullet setting. You'll have to play more fast towards the end. 

There are separate tournaments available for each time format with a variety of time controls. For example, blitz has 3|0 and 3|2 tournaments. Bullet has 1|0 and 2|1 tournaments. There are variant tournaments with different time controls too.

The tournament system are of two types: Swiss and Arena. The latter was developed pretty recently. Swiss goes like, you play an opponent in each round, get points and when the rounds end, who has the most points win. Arena is pretty much the same. Except there aren't any rounds. You just play on and on. Instead of rounds, the tournament has a fixed duration. Once the duration ends, who has the most points win.
