Flags Challenge is the ultimate quiz about the flags of all world. There are many games like this on the market but I think it has an original gameplay, fun sound effects and cool features like: Ôÿà 200 country flags to guess Ôÿà Real Time Multiplayer Ôÿà Online leaderboards Ôÿà Achievements For more info visit: www.flagschallenge.com. Flags Challenge is my first game developed for Android, iOS and Web. I developed Flags Challenge for fun. It was about wanting to create something. In 2013 I came across Beginning Android Games, a really good book by Mario Zechner, that was my first step into the game development world. I learned a lot of useful concepts by reading that book. In 2014 I downloaded libGDX and I started to learn the APIs by running the sample projects. Soon after that, I realized that I had all the right tools and concepts to start thinking about what it would be my first game.
