Lotto Logic Professional is a number-picking analyzer which handles more than 90 percent of today's lotteries worldwide. It allows selections of numbers (from those hit most often to those that seldom win) as well as quick picks and personal choices. Range Finder is one of the many exclusive features you will find in Lotto Logic Pro. Instead of just entering past draws and relying on static sets of past draws for results, Lotto Logic will run through the entire database of past draws and find the range or ranges of past draws from which you should select numbers. This update adds the Auto Archive tab to help clear outdated draw results without having to delete them.
