To quote an excerpt that sums it up: "A sit & go is similar to a tournament. Unlike a tournament, it doesn't start at a set time, but when there is a quorum. A sit & go has a predefined number of players. There are sit & gos with 2 players, 6, 9, 12, 18, 180, 360, etc. Sit & go formats are added year after year. What differentiates a tournament from a sit & go is that it will start when the number of entries has been filled".

You'll see that the strategy in these types of sit'n'go is a little different from conventional sit'n'gos.
