You might want to rethink your number idea. You said if someone were to pick 134 and 431 came up they'd win right? Does this mean if 413 came up they'd also win? In this case there are only 36 different combinations of three different numbers between 0 and 9.

Since numbers cost 200 each thats 7200 dollars to pay off 100,000+. Those odds aren't right. If I had 18 members in my gang we could buy every combination of numbers and break the lottery.

I think you should stick with picking the exact number and having each ticket cost 100 dollars or 110 dollars. This would give even odds or a little above even odds.
