Tic Tac Toe for Android done with Unreal Engine

I decided to make a Tic Tac Toe game using Unreal Engine 4.16. with Blueprint and C++. It has some cool variations of a typical Tic Tac Toe game.

You can download it here: https://play.google.com/store/apps/details?id=de.tomhoefer.tictactoefree – free to download and play, no in-app-purchase!!!

I would love to get some feedback from you guys! If you have any questions about how I made the game, just ask anything you want. Nearly all is done using blueprint with the exception of the AI of the computer opponent - I did implement the minimax algorithm using c++. For me it was more approachable to use a normal IDE for implementing a recursive algorithm.
