Different types of Sit & Go :

Rebuy : Unlimited or limited rebuys during the first 5 levels. (startstack : 2000 - rebuy : 2000 - add-on : 3000)
Freeze Out : No rebuy opportunities. (startstack : 5000)
Double Chance : 1 rebuy (5000) or 1 add-on (7500) possible.
Second Chance : Possible to use the special rebuychip when out of chips. Once at the final table the rebuychip becomes unusable and will be removed from the table.
Bounty Knock Out: For every opponent knocked out from the tournament you recieve his bounty. (startstack : 5000)
Deepstack : Startstack : 10000 jetons. (Double amount of starting chips in comparison to a regular Freeze Out)

For the moment there are 7 tables available. So max. 70 seats.
