My complaint:
I have went up 3 levels spending 1.5 billion coins on either level for not 1 gold card yet I read online if you spend between 1 million to 1.5 million dont get a new card to move onto the next but dont go to far infront incase you kiss golds on previous levels it’s an absolute joke.
Suggested solution:
A think there should be a gold card every 50 chests or something especially the amount of coins they end up costing.
