Unfortunately I have to take my review from 5 stars down to 2. The only reason is because once you get to the aquarium park after finishing your upgrades, the levels become impossible without shuffle buffs. I had almost 170,000 cash and now I'm down to 3,000 in a few days having to watch constant ads if I want to play more than one round. The levels nos to take upwards of 7 tries at $3,000 each before you get a lucky shuffle. I'm a few minutes away from uninstall which would be an honest shame.
