I have a suggestion. When you win Yetis treasure the first time you win a lot of goldcoins and a deck card. The second time I noticed that you don´t always win the same amount of goldcoins. I got a lot lesser when I played some months ago and you don´t get a card deck, you get free spins. My suggestions is that instead of the free spins you get another card deck you don´t have already or you get for example 5 parts of a card deck you don´t have. You should only get the free spins if there is no more cards to get. I also think you should win the big amount of coins every time you play because it costs a lot of coins to play.
