Worst ad optimization I've ever seen. Most of the ads crash the game without giving any reward. The ones that don't crash still don't give rewards half the time. I've watched as many as 12 ads in a row for zero reward. Some ads have no option to close so you have to close them manually (no reward again). As if all that wasn't bad enough, the game also tries to sell you like 3 different packages every time you open it.

Decent game. Playing it through a rewarded app. Main problem is ads. They're atrocious. You can watch an add all the way through, it'll even say rewarded and there's an x to close it out. But when you get back to the game? Nothing. Even got an achievement reward once for watching ads, but still prompts to watch the ad again for the ad reward. One time it took 6 or 7 watches to get the reward, not closing it out early, watching it all the way through.

I put this game off for a long time because I thought it was a run of the mill idle game. While it is very similar in the brain scratching territory of satisfying incremental upgrades, it has its own style that shines not because it does the reliable and old stuff well but also because it has its own flavor of the genre. Premium currency is abundant as are summons and upgrades which is great because you arent experiencing a need to buy to get ahead. its well done. and its fun.
