If you play online roulette, taking chances or putting your trust in luck, you can really have trouble. You need a method. Pay ATTENTION, you don’t need to buy the method (it’s illogical someone could think to sell it). The method has to be created, and to do this, you need a tool to not waste much time…or too much time. Roulette 3+1 is a tool to create methods based on innovative theories. It is composed of 3 PC programs, that you can download from the internet through a simple a process explained in the eBook. They permit you to study the behaviour of numbers to anticipate which one is going to come out. Each program is independent from the others. The ARROW TOOL calculate which is the missing number that will be extracted to be put in the vertex of an arrow composed of strings of numbers. The ZONE TOOL is based on remaining numbers in specifically created zones. The SPREAD TOOL is based on the difference of quantity of numbers belonging to each combination. Furthermore, you can implement everything with the random number generator, which is the same of online roulettes. In this way, the validity of the study of methods is more specific and fast. Point out that search a method without a tool is like to drive a nail (method) without a hammer (tool), or fishing a trout (method) without a fishing pole (tool). A good fisherman doesn’t design his own fishing pole, a good pilot isn’t the one who design and make the car. These were examples to understand the difference between buying a method that no one would sell it if it works. Buying a tool, instead, can be a source of income for the person who projects the tool and for the one who buys it and learns how to use it.
