As you master the difficulty of a level, move the game up a notch for a greater challenge. Im stuck on 3 suits as my ventures into 4 suits, while not impossible, offer too few rewards (wins). Maybe you can do better. Great game. For recreational purposes, I find level 2 most interesting. Not too difficult, yet challenging at my playing level. I am enjoying the newly added animations that display after each winning game. Ive counted at least 22 of them so far.
