Flappy Bird, Threes and Clash of Clans is definitely what’s happening in the iOS gaming world at the moment. The addictiveness and challenging nature of Flappy Bird has ensured that it still remains installed on millions of iOS devices, even though the developer has permanently removed it from the App Store. The popularity of the annoying little bird has managed to provide a ray of hope as indie developers and small game studios try and compete with the larger development houses. As one bird disappears from the mobile gaming world, it looks like we are set to welcome in a whole new family of mischievous aves in the form of a new Angry Birds Stella courtesy of Rovio.
