Interesting challenge
there are no odds on the first because it is the first one-no chance of dup.
2nd one 12 out of 17 or 1 in 1.4166
3rd one 6 out of 16 or 1 in 2.6666
the same would be for the next machine.
I actually did this with the Plaza Patriotics when they came out and it was on a 3 coin payout

Don't know if this is right but it was fun trying to figure it out
