I've played similar games. this one relies on ad watching and clicking here and there. just to do your daily quests, get equipment and so on if I say 100 ads could be enough to get all the stuff. there are few packs to spend money on, but on the high side. 2 stars as it is not too boring, still idle game. uninstalled due to high number of ad watching requirements.

Hi! You can choose to watch ads or not by your own will. Ads can be very annoying sometimes. We wish we could disable them forever. At the same time, ads allow us to maintain the game, add new features, and make it available for everyone without any charges! We hope you can understand that. Thanks for your patience and support!

The game is fun for tbe first 30 min, after that it's just an Ad hell, you want the game to go faster? 1min ad, you eant to claim half of your dailies? another 1min ad, its just ads for everything, everywhere, and on top of it they have the pair to make the ad removal $30, and if it wasn't enough, you hit the F2P wall pretty early on. there's better options put there, good looking game, but this sickening greed on phone games is what makes them this unbearable.

This game is a pretty good time killer. I haven't spent a dime and I don't plan on it either, I would say it is definitely f2p. Ads aren't a big deal either... you can watch them whenever and they aren't forced! Of course it's an idler so you can take a break from the game and still get rewards. All in all it's a decent game! I would recommend it if you're into idlers.
