You can even choose the number of coins per line, which increases your odds of hitting a winning combination.

As a result, the odds of losing a certain symbol became disproportionate to the frequency of their appearance on the physical reel. Now, however, the symbols will only appear once on a player reel, although they may be occupying several stops on several reels.
