I have just released a game called Zmath. The game is only available for Google Play right now (waiting for app review on App Store).
About the game:
Zmath is a fun twist on the classic Snake game we all know and love. Solve the math equation to find the right answer and watch your snake grow longer and longer… Swipe to sssslither your way to the right answer while avoiding hitting yourself, the walls or the wrong answer.

Would love to get some feedback
