It looks correct to me
If you win you get your symbol at the beginning, and your symbol can’t fall off the end when you win.
This way the last symbol that is not a symbol of the winner (in this case my beer) gets dropped, and that was your bee
Without this several other symbols would still be there. But to win 15 matches continuously in a row is close to impossible
It wasn‘t even my idea though, we could change this anytime. I donˋt care
