i spun like 50 times, never got a single letter of the word JOKER ... pointless/dissapointing feature....
you may see the letters rotate, and you may even see them partially above or below the winning line,
but you won't get just a single letter in winning column.
that would be pointless, as that Letter would take the place of a card.
Would you rather have two cards at 50%, and Two letters show up,
or
4 Cards at 50% and no letters?
But Stars are mixed in with the Cards !The reason stars are mixed in with the cards, is that you Also win something from a star.
a single joker letter wins you nothing, so it would take away from the win amount.
Anyway, that is my take on Why you don't see the letters on the winning line show up at random.
You will only see all 5 joker letters if that spin is a winner of a joker card.
