Assuming a wild doubles a base win, and wilds aren't cumulative you have:
You have 1 line 5oak aces x1
You have 7 lines 5oak aces x2
You have 1 line 5oak character x2
You have 4 lines 4oak tens x 2
SO AT BASE STAKE you have:
15x5oak aces@2.66-1 = 40-1
2x 5oak characters@6.66-1 = 13.33-1
8x4oak tens@0.33-1 =2.66-1
=EXACTLY 56-1
=EXACTLY $168 if playing a $3 stake.
Add your base stake to my table above plus the game awards for those lines and you should have your correct payout.
EDIT I have done this for you:
Above.
You have made a mistake in your interpretation of the paytable win-stake ratio.
The slot is correct.
End of.
BTW Before you got the $168 spin, you got 70c by either getting 3 jacks or queens, hence your total shows 168.70.
To settle this issue, check the freespins BEFORE your $168 spin, and you'll see the 70c win.
This shows my reverse engineering is correct, as how could I know this otherwise?
The slot has paid you exactly to its paytable. Please drop any enquiry or complaint you are pursuing against the casino, as you'll look a numpty....
