Dwoods,
you could also make a simple wheel.
Break the large group into small sets of numbers of 2 or 3.
Combine them together in sets of 2's for a better chance to win, 3 for a budget draw.
eg: a group of 12 numbers could be mixed to cost either
$20 with sets of 2 numbers
(1,2,3)(1,2,4)(1,2,5)(1,2,6)(1,3,4)(1,3,5)(1,3,6)
(1,4,5)(1,4,6)(1,5,6)(2,3,4)(2,3,5)(2,3,6)(2,4,5)
(2,4,6)(2,5,6)(3,4,5)(3,4,6)(3,5,6)(4,5,6)
3 numbers in each set for only $6
(1,2)(1,3)(1,4)(2,3)(2,4)(3,4)
Even 15 numbers mixed into sets of 3 costs just $10
18 for $15
It's not bad price for the cheap wheel, but it's less chance to win.
