4th game: All or Nothing

Basic Rules

The only difference between this game and the Balance game is that the rolled marble isn't changed but it is duplicated on the expense of the opponent. (You change any of the opponent's marbles to the color of the rolled marble.)

2nd Version

Cooperative version is also possible. (See Balance.)

1D6 Version

Your starting value is 3.

Your roll 1d6. If you roll above the value, lower it by 1.
If you roll below the value, raise it by 1.
The maximum value is 6, the minimum value is 1.

Analysis

This is a catastrophe phenomenon. The system starts to differ from the balance slowly, then it shoots to the stars.

The cooperative rule can make this even faster.

In RPGs

You use this if you want to have an outcome inevitable. The question is only: wich will occur. The earlier you do something, the better. The later, the more you have to do to change things.
