A Sit N Go or SNG is designed to be a fast paced tournament style experience.
Structure
Sit N Go's start immediately once a set number of players have registered, rather than at a fixed, scheduled time. You "sit" down, and as soon as all seats are filled, the tournament "goes" which is also outlined in the Event Details section before you register for the tournament.
Like any tournament, players buy in for a set amount, receive an equal number of chips, and play until one player has all the chips.
The pacing for the tournaments are often incredibly quick, as denoted by the "Turbo"  structure in the screenshot above, and are designed to be completed usually within half an hour of the start time.
This is a great option for those who want to play a tournament style game but may not have 2 or 3 hours to spare for a standard tournament.
Payouts
The prize pool is pre-determined and is usually paid out to only the top 3 finishers.
You can always check this prior to registering by tapping on the Rewards tab while the tournament page is open as seen below.
If you've registered for multiple Sit N Go's and are going to be unable to participate once it fills you can always unregister from the tournament itself.
