I've been looking at this in a lot more detail tonight (sorry - been too busy before!) and there still seems to be something amiss.
HIGHIQ won $5.20 on the spins BEFORE spin 12, so the total of $153.70 means spin 12 must have given him $148.50
I created an Excel spreadsheet to generate each of the 243 different win-lines and then calculated the wins.
Part of the problem depends on how exactly the player interprets the rules:
If one assumes a "pay way" means the same as "win-line", then the slot should pay out for symbol combinations on each of the 243 lines separately, then add them all together to make a total.
Using my spreadsheet, I calculate he should have been paid $332 for spin 12.
These are all the winning combinations by line-number. (M = Man - I don't know his bloody name!

)

However, on the actual pay-table you will find this rule:
View attachment 37926
Now I think it's pretty unlikely, but this COULD be taken to mean that you can only count the same 3, 4 or 5 symbols once each.
e.g. Above the first 3 wins are:
1. M W W A Q
2. M W W A M
3. M W W A A
This rule COULD mean you only get paid for one of these combinations, because the M W W are the same 3 symbols in each line.
If that was the case, my spreadsheet would look like this:

But now the total is $205.50 = still higher than what was paid.
I think this is a really serious issue which needs a proper & thorough investigation, which is why I advised HIGHIQ to PAB last week.
Unless... I have made an error in my calculations. If anyone can spot an obvious mistake - please shout!
