I'd like to see a "dark" version of the game. Here you only know the number of points that you personally have left as well as the total (or average - same thing) of all those still left in. Also you would see the amount that the players who dropped out bet.

Imagine the round with 3 remaining players when you have 1000 points and the total points = 3500. What's your bet?

The last round shouldn't be played, whoever has the most points of the 2 remaining players is the winner.
