This mini-game was designed and developed at Pixcube. It has a simple "one-tap" game mechanic but its UI/UX design is more advanced. It includes a random loot box, statistics and a achievements system. Different cars and tracks can be unlocked, to customize the look and feel specifically. Try it out, if you're bored :)
The User Interface was the most challenging UI I've developed for a mini-game so far. I also developed a "random loot box" system, so new cars can be unlocked. Because it's free to play, I've also implemented monetization frameworks in terms of display ads and in-app-purchases. Furthermore I've programmed an achievement system, so the user has some challenges to focus on and continues playing - thanks to the generative aspect of the game.
