I have been using Expert lotto for some time now & find it an excellent ( the best ) in my opinion, lotto programe ever made. When you first look at it , you are inclined to give it a miss. However, when you delve further into the program it really is fantastic just what you can do with it e.g. the winning numbers table which has odd/even tables , high/low tables, sum tables, & too much more to mention.You can see & print out visual tables for regular & odd & even numbers ( sort of a grid type layout). It has a tremendous amount of filters for use (more than any other program I have seen........& I have bought most of them!) They also have a unique"winning history " system that is diferent to any other system I have seen that guarrantees a winning jackpot if your selection comes within a plus or minus 10 range of numbers. It can be used for any world wide lotto, including powerball, includes or excludes bonus numbers, and can be very effectively used for Keno. AS it is a fairly new comer to the market, a lot of people haven't heard about it or tried it. The support they have is fantastic & any questions you have are always very quickly & effectively answered, & they are always open to any suggestions that anyone might have to improve the program with regard to new inovations or tech problems anyone is having with the program. I strongly recommend anyone to try the program (a free unlimited use version is available) & it is definately well worth the cost of buying it. (as new versions come out you can upgrade free as well!) I found the best way to become familiar with it is to download the user manual, print it out & work your way through the program .....you will be very pleasantly surprised once you get familiar with it, just what you can do with it. The authors of it are obviously very intelligent people, and although based in Czech their English is over all very good.
