No, it has to be every participant gets 100% of a large pot. The comparison is "YOU get a car" to all attendees at an Oprah show... so let's assume a car in terms of WZ is 1000 coins?
This cannot be controlled, cause if you and an other player make a deal for a 500 coin entree fee game, you both spend those 1k coins on games. After that one surrender is a game, and the other surrenders in the other game. If you don't trust the other player you could even use a custom scenario for this....
