This game is technically 4 days old in the U.S. and there are people who are already losing a ton of games at bronze, silver, and some have already even moved up to gold and are losing... you need to fix this. A 4 day old game should be fun and not try to make people quit.
Imagine brand new players to this game having only a 20% chance of winning games... do you think they will want to stick around? The answer is no. Please fix your bonus game and prime game algorithms and make this game more fun for everyone and not just the few who spend tons of money.
