The most addictive game so far this week is without a doubt 2048 (sorry Flappy Bird), a simple web based numbers game controlled by the arrow keys. Swiping on the iPad works excellent as well, making it easier than ever to
abuse play all the time.
The main goal of the game is to get a 2048 block which is done by combining blocks with the same number to form a superblock containing the sum of the smaller blocks.
There are striking similarities with the popular Threes game for iPhone, but there are subtle differences as well, making this game all the more entertaining and addictive. When moving blocks for instance, they are always moved to the edge of the screen and not just one block away.
The best part however is that this game is completely open source and available on GitHub to play with.
