Why: There weren’t many (if any) apps that distributed profits back to the players so I believed that this concept could be interesting. Being interested in poker, I decided it fitted well to this idea as freeroll tournaments were popular on poker sites. Some of my calculations showed that if there were enough participants and the tournament was long enough, it could be possible to offer a million-dollar price pool.
Tools: Unity (game engine), C# (language used in Unity), PHP (backend), MySQL (database)
Reason to quit: Google Play Store's bots rejected this claiming it violated their rules. I did not agree with the conclusion but I could not get to talk with a human. The game had some bugs I was not available to find because the code was written into a few files making it messy.
What I learned: This was my first bigger project and I learned the importance of clean code.
