you're very correct, sir. the rounding seems to be at random, too. anyway, the lines are:

4 teams 10-1
5 teams 15-1
6 teams 25-1
7 teams 50-1
8 teams 100-1
9 teams 200-1
10 teams 300-1
9 out of 10 teams 20-1

Standard payouts and ties lose. The rounding is NOT random. Notice how many 3 and 7 point lines the cards have. This is because ties lose. The other lines are off because the guy selling these knows which teams are more likely to be picked often. New England is hot, make them 20 and he'll still get more circles on NE.
