Looking at this answer which essentially says "No, there is not an app" but got comments saying "You know for a fact there are no coding games for Android?" implying that to answer "No" you must provide proof that none of the 200K android apps meet your needs.
Compared to this question which has no answers, but a comment that says "I've also looked and have not seen anything available at the moment.". That comment is logically an answer, but it is an answer that says "No" and was posted by a mod.
Is there a preferred way to answer "No" to "Is there an App that does ABC?"?
