The MARIGNY app offers you the possibility to calculate the characters and appearances on the simple odds of roulette according to the data of Marigny de Grilleau. In his book "Le Gain scientifique d'une seule Unité", published in 1926, Grilleau described the determination of figures and appearances of figures on the simple odds of roulette and developed a betting strategy from this. The German translation of his work was published in 1977 under the title "One piece per attack".
Finding figures and appearances of figures on Roulette Simple Odds is a very labor intensive process without the support of software. The occurrence of deviations ("ecarts") of equally probable events is easily overlooked. However, these are prerequisites for the composition technique according to Marigny de Grilleau.
The software MARIGNY helps to determine the frequencies of the figures and appearances. It shows the uniformity of permanence based on true random numbers and indicates deviations in the frequency of equally probable events according to Marigny de Grilleau's rules. An understanding of how figures and appearances are identified on Roulette Simple Odds and the ecarts that result is a prerequisite for using this software.
No recommendations are given as to when or how to play a bet or bets of roulette in any given situation. For this we refer to the book "One piece per attack" by Marigny de Grilleau.
