The Irish Lotto number generator is packed with tips to help you with each filtering option. To read a tip, just click the icon next to any of the form elements. You can find out more about this app by reading the the Advanced Number Generator help pages.
Most of the data needed to configure the filters can be found in the Irish Lotto matrix.
Here is where you can find the most common, least common, most overdue and Irish Lotto pairs. On any of these pages you can use the left/right buttons at the bottom of the page to view related data (e.g. triplets).
You may also need some of the information that's on the numbers story pages.
And the numbers that followed or did not follow other numbers are available at the bottom of the latest results page.
