There’s two ways I played this game.
1st way was paying to play, by buying gems & coins for using the slots. I spent almost $200 to only reach rank 3. Now mind you, they’re dollar conversion is different for each country. For example “100 gems for $5.99,” that equaled to $12. I’m located in America, so anything in the store you see, it will be doubled for Americans. I even contacted support and that’s what they told me.
2nd way I decided to play was spending less money. I found myself checking every other hour to gather my resources, it was more time consuming to play at this point because this would take ALL DAY to play, to upgrade, gather resources. You’ll need heros, they’re stuck behind having to pay, and if you’re in America, you’ll be paying double.
I tried a different strategy, where I didn’t care to play in the events anymore (the events is where you’ll get your heros, more gems and hero skins to change), until one day my card was charged from this game. $13 was randomly charged, I checked in game to see what did the $13 went to, I tried to find a receipt, none, I went to purchase history and it was taken out of my account the day I decided NOT to play. I contacted Apple and the returned my money. You’ll never win unless you want to spend $400-$500 dollars, if you have the money kudos. I deleted this money stealing game.
