I recently tried the game Star Numbers and found out this is actually a math game that I would never play in my life. I'm not exactly a math fan and playing a game involving math would not be something I dream of doing. Gameplay wise this game is simple. You just solve the math problems that show up, and earn gems. What you can do with these gems is beyond me, I didn't find any gem store or any way to spend them, they just accumulate while you play. The games layout is messy and overlaps each other many times while trying to input the correct numbers, which makes things difficult at times to put the right answer. There's not much else to the game after that. Just repeat the same thing over and over with the maths problems progressively getting more difficult as you complete the levels. According to the store page, 15 minutes a day of this will help your brain, so perhaps this is good for parents to force their kids to play. Other than that, I'm not quite sure who this is for. Unless you are a die hard math lover. Then this could be for you.

Another gem without any in-app purchases or ads..there arent any in game currencies either...the perfect game to play ACTUALLY for FUN,the perfect game to relax ,the perfect game to train your brain which will worth every minute you spend in If you are struggling with calculations in school  try playing this game...this game will make you better(as teachers says practicing maths is how to get good at maths...this game is a good app to practice)
