I know theres a way to leave in the best tickets , what I like to do is leave in the worst tickets

I only have the Hobby version , I would like to back test say the Uk lotto to find the worse 5 or 10 tickets

So I like to back test the 1486 past draws ....against the 13,983,816 combinations and for example . leave me with
the 5 worst preforming tickets so far

Tickets
2-5-17-32-38-45...... only hit 3 numbers 4 times
4-9-14-22-23-35....only hit 3 numbers twiced
7-15-18-33-34-47....only hit 3 numbers 5 times
11-13-15-22-28-42....only hit 3 numbers once
6-7-14-23-32-39 ... only hit 3 numbers twice

Above stats are all made up ... but you know what I mean

well, you could use 'match winning numbers' filter specifying you want maximum of e.g. 5 matches of three numbers.
other than that there's no filter to find the 'worst' tickets but feel free to submit a feature request for it.
