Roulette Game Strategy / Martingale system

Martingale winning system is that we are constantly betting on the same color and doubling the bet when we lose.

For each game you will walk away with at least € 1 without the risk of losing! Maybe this seems to be just a little, but in the online roulette you can perhaps earn that euro in a minute!
This means a gain of 1,800 CZK per hour! Earned by fun!
