Must use coins to play each question. – Geography Quiz Game 3D Review

I don't mind ads or optional in app purchases but I'd like the chance to play it before having to look at buying something to play if there's a so-called "free" version. You must spend coins before answering every single question. Aside from being distracting, it's not a very good quiz game if the winner can just buy their way to the top. I'm looking for a good geography game for my friends kids to play during an upcoming road trip. This is definitely not it.
