Progressive Total KO Tournament is a special type of bounty tournament available on PokerStars in which the entire buy-in goes to fund each player’s bounty.
There is no regular prize pool (unless the tournament falls short of its guarantee) meaning the only way players can make money is by eliminating other players.
The MICOOP 2021 schedule does feature such a format. It is marked #60 and is scheduled to take place on March 8. It comes for a buy-in of $20 and is structured as a heads-up, turbo, zoom event.
