My experience has been similar to the other negative reviews. Have played for several years, and actually made it to 21,000,000,000 coins, only to be broke now. Lost most of it during the quests where I was required to complete outrageous things like “win 4.3 billion coins”. Seems the higher the level, the more you are required to bet per spin in order to win. Now at level 2073 I am still expected to win 147 million in the first of the three daily quests, even though my coin balance is only 157 million! The quests stopped being fun once I lost most of my coins and could no longer complete them. When I was able to bet 3-5 million per spin, I would receive 3-5 SlotoCards and was able to complete several sets. But now that I can bet 500K to 1M (or only play for 5 minutes), I rarely get a SlotoCard, and if I do, only one at a time. Apparently the album feature is only for the “high rollers”. And the worst part, is that I NEVER receive the entire amount I win on any “big” or “mega” win. For example, my balance is 78,000,000 and I win a 10,000,000 “mega win”. My balance after that is more like 85,000,000–they keep a portion of every large win. Every time. I have complained via the link in the help section and the reply is always that their “records” do not substantiate my complaint—then they give me a “gift” of a few million coins. I seriously don’t understand why the developers use this strategy. Time to find a different slot machine game😕
