it depends on what level you have, if you also play events you can still have 30 in some cases, but this is rarer and is once a day with the same 9 ingots, the levels with events differ in each game, and you will see your friends if they have reached that level , that's all
try to do 10 levels a day or more and maybe events will start to appear, success seems to me that at 75 the boosters trail event will appear, it will help you a lot to climb
