It's not a question of whether or not it's harmless. It seems to me that it plainly violates the "apps that simulate gambling" clause. It looks and plays like a slot machine. That's different from Jetpack Joyride, which is a side scroller that has a brief slot-machine element that's not really central to the gameplay. Almost all video games have random elements but they're not gambling themed. I'm not Muslim but my understanding is that the Qur'an views gambling with the same level of condemnation as it views consumption of alcohol. Games with nudity/sexual content, homosexual characters, alcohol, gambling, etc., are (unfortunately in my opinion) banned in multiple Islamic nations.

As long as we're on the subject, the Google Play storefront of this app is very much lacking in any reason why someone should want to plunk down US$5 for it. Maybe an embed of the release video? For that matter the release video itself could benefit from having a voiceover that explains a little of what's going on and makes it sound fun.

(Parenthetically I was surprised to just now find out that this game was in my Steam library. Was it in a Humble Bundle at some point?)
