Despite having a very simple concept, calculation games aren't at all boring. 2048 for iPhone, a game in which we have to add different amounts to reach this figure, is a clear example.
Playing with powers of 2 had never been so amusing...
In 2048 we'll find a panel with tiles on which the figures that appear are powers of 2. Thus, we'll have to move the tiles left, right, up and down, so that when they touch other tiles of the same amount, their value multiplies by two. You'll start off with tiles the values of which are 2, and as you can imagine, your aim is to obtain a tile whose value is 2048.
Once you start, you won't be able to stop playing
Once you start playing, you'll find out that this game is so simple that it's almost ridiculous... but you're not going to be able to stop playing. You'll find yourself immerse in a whirlpool of more and more movements to manage to double that tile that's holding out. If you're looking for a pastime to kill your free time on the subway or while you're waiting, don't hesitate and download 2048.
