I agree with that. I was aware of the jackpot sharing rule. What I posted was not the finished product, just the one-player case.

Yep.

Thank you for the confirmation! Did you do it with calculus? I did a Markov chain and verified it only for hitting all 10 numbers with your usual method.

I didn't want to fuss with creating and solving 252 equations for all the ways to hit exactly five numbers, but maybe you know something I don't.

I dont think Poisson/calculus would be an efficient method for this problem. Too many combinations to be summedQuote:WizardQuote:ThatDonGuyI get the same numbers you do. To be more specific:

No - I used brute force computing. Well, I suppose it's identical to a Markov chain.

However, the probability for 10 is simple; there are 10! permutations, each of which has a probability of 1 x 2 x 3 x 4 x 5 x 5 x 4 x 3 x 2 x 1 / 36^10 of occurring, so the result = 3,628,800 x 14,400 / 6^20.

First, I generated all 10! = 3,628,800 permutations of {2, 3, 4, 5, 6, 8, 9, 10, 11, 12}:

1. Start with {2, 3} and {3,2}

2. For each number from 4 to 12 (except 7), replace each previous permutation with multiple permutations where the new number is in each possible position (e.g. replace {2, 3} with {4, 2, 3}, {2, 4, 3}, and {2, 3, 4}; when all of the size-3 permutations are done, replace {4, 2, 3} with {5, 4, 2, 3}, {4, 5, 2, 3}, {4, 2, 5, 3}, and {4, 2, 3, 5}).

Then, for each 10-permutation:

1. Calculate the probability of the first 5 numbers coming up then one of those numbers or 7 (i.e. a 5-roll win).

If the first five numbers are {2, 8, 6, 10, 3}, this is 1/36 x 5/36 x 5/36 x 3/36 x 2/36 x (1 + 5 + 5 + 3 + 2 + 6)/36.

2. Do the same for the 6-roll wins, the 7-roll wins, and so on through the 10-roll wins.

3. Sum the 5-roll win probabilities, then divide by 5! as each permutation of 5 numbers appears in 5! of the 10-permutations; this is the overall probability of a 5-roll win.

4. Sum the 6-roll win probabilities, then divide by 4! as each permutation of 6 numbers appears in 4! of the 10-permutations; this is the overall probability of a 5-roll win.

5. Do the same for the 7-roll through 10-roll wins.

Rules paragraph 1:

The All bet should be the All/Tall/Small bet.

Maybe I am underestimating the intelligence of your readers, but Id like to see an explanation of what the expected return per $1,000 means.

Id also like to see a comment, or even a chart, that unless the progressive is at least $1,500 per player, it pays less than a nine hit pay out - or is there a special rule for that?
