I don't know if this feature has already been included or not? In other king games, there are these features that allow players to collect a certain item to get rewards, for example in farm heroes super saga if you make 100 super cropsies you get a certain amount of coins, which you can use to buy boosters.
Maybe this is something cc can add to the game so people are able to get boosters.
Also, I thinkcoins should be added, like in farm heroes super saga, so that boosters cn be brought.
