Petals
The simple things in life are often the best, and Green-Eyed Games has managed to turn a simple sliding-block puzzle into a game about flowers, just by arranging blocks the right way. The rules of Petals are as simple as the idea behind it: click to combine like-colored tiles in a grid, but avoid combining tiles of different colors. That's all there is to it, and it's a great way to spend a few minutes stretching your mind. You don't even have to water it.
