I will try and simplify how to work it out as it is not obvious unless you do the necessary calculations.
There are 3 stop positions on each reel that can contribute toward a win.
If you think of the top symbol on each reel being in position 1 the middle in position 2 and the bottom in position 3 you can then see how wins are made up.
The first number is the position of reel 1(1=top,2= middle,3= bottom) the second number is the same for reel 2 and 3rd number the same for reel 3.
The "-" is to separate each combination and "--" to separate blocks of 3.
Note were only dealing with the first 3 reels here.
1,1,1-1,1,2-1,1,3 --1,2,1-1,2,2-1,2,3 -- 1,3,1-1,3,2-1,3,3
2,1,1-2,1,2-2,1,3 --2,2,1-2,2,2-2,2,3 -- 2,3,1-2,3,2-2,3,3
3,1,1-3,1,2-3,1,3 --3,2,1-3,2,2-3,2,3 -- 3,3,1-3,3,2-3,3,3
As you can see these are the 27 possible combinations of the first 3 reels (3x3x3=27)
Setags example was (4 reels in play) but we can still see how the wins work.
Example stop positions for reels
1 2 3 4
9 J A B
W W W C
10 Q K T
So using our table we can then see exactly what combinations we are looking at.
1,1,1-1,1,2-1,1,3 --1,2,1-1,2,2-1,2,3 -- 1,3,1-1,3,2-1,3,3
2,1,1-2,1,2-2,1,3 --2,2,1-2,2,2-2,2,3 -- 2,3,1-2,3,2-2,3,3
3,1,1-3,1,2-3,1,3 --3,2,1-3,2,2-3,2,3 -- 3,3,1-3,3,2-3,3,3
Translates to (Where * shows winning combination);
9,J,A-9,J,W-9,J,K--9,W,A-9,W,W*-9,W,K--9,Q,A-9,Q,W-9,Q,K
W,J,A-W,J,W*-W,J,K--W,W,A*-W,W,W*-W,W,K*--W,Q,A-W,Q,W*-W,Q,K
10,J,A-10,J,W-10,J,K--10,W,A-10,W,W*-10,W,K--10,Q,A-10,Q,W-10,Q,K
We can now clearly see that when substituting the (W)ild symbol for winning symbols we have.
9,9,9
J,J,J
A,A,A
W,W,W
K,K,K
Q,Q,Q
10,10,10
The 4th reel was;
B
C
T
So since we already have above the only winning combinations we simply need to add this on and see if it contributes to four of a kind.
(This now makes total combinations 27x3=81)
9,9,9,B-9,9,9,C-9,9,9,T = 3x three 9's win
J,J,J,B-J,J,J,C-J,J,J,T = 3x three J's win
A,A,A,B-A,A,A,C-A,A,A,T = 3x three A's win
W,W,W,B-W,W,W,C-W,W,W,T = 3x three W's win or 1x four B win, 1x four C win, 1x four T win (largest win pays only)
K,K,K,B-K,K,K,C-K,K,K,T = 3x three K's win
Q,Q,Q,B-Q,Q,Q,C-Q,Q,Q,T = 3x three Q's win
10,10,10,B-10,10,10,C-10,10,10,T = 3x three 10's win
So Simmo is right and it would only pay 1 x four castle, 1 x four boat and 1 x four Thor.
This is because the 3 wilds are only represented on one line(2,2,2) going into the fourth reel and each of these symbols is represented only once.
So their winning combinations are 2,2,2,1-2,2,2,2-2,2,2,3 respectively
If the boat,castle or Thor symbols were on reel 1,2 or 3 you would then get multiple wins and also obviously any other wild would do the same thing.
Hope this helps because it can be quite complicated.
EDIT.
I read Simmo's post as stating there were four castle wins etc but now realise he means 1 win of castles etc so I have edited my post to reflect this.
