Systems without progression
In contrast to the systems, in which the stake is increased after the coups, depending on whether it was won or lost, there are also systems that manage entirely without progression. So with them, each sentence has the same height. This way of playing is called mass égale. It is hoped for a positive Ecart that the chance that is bet appears more often than one would expect according to the rules of probability. The mass égale game is actually only worthwhile for the game with the higher chances.
