About the author of the softwares
Always fascinated by numbers, it's after a long period
of work and research that I made a discovery related to the combinatorial calculation and the lotteries in general.  I decided to let all the players take advantage of it by creating softwares dedicated to Keno and Lotto. Resulting from a hard work, they have a powerfull search engine for combinations allowing a revolutionnary calculation depth.

Before, due to the important limitations (mainly the calculation speed), it was impossible to get into the heart of the problem.

From now on, by choosing payras softwares, you will be able to finally take advantage of the power of your computer in order to know precious information resulting from an exhaustive approach of all the keno and lotto combinations.

Keno Expert USA, Keno Expert USA For Casinos and Loto Excel Universal can deal plentiful data and extract from it invaluable results.  

This wealth is just a click away.  Don't hesitate to discover the softwares and don't forget that I'm at your disposal for any question.

So test them, calculate well and have fun !
