I started playing EuroMillions 3-4 years ago.
I won on the first grid I played (I had ticked the star+).
I first played random combinations, then i tried to find an explanation how the numbers dropped. I tried with probabilities, but in vain. I then analyzed some predictions on other websites, and that's when i filled some spreadsheets with probabilities, predictions, and previous results.
0. Spreadsheet
By studying previous combinations, I found "patterns" and "trends", which helped me find some combinations.It was becoming tedious to search for similar combinations each time, copying and pasting predictions from several sites into a spreadsheet.
So I wanted to bring together statistics, predictions on combinations and my winnings (with statistics) in a single application.
