Every week, Apple makes a game or app available for free on the App Store to all of its customers.
This week the game was chosen Shades, from UOVO.
Shades are a kind of modernization of the Tetris style, in which you need to pair blocks of the same color horizontally.
The problem is that when two blocks of the same color touch each other, they blend into a color of greater tonality, making the game very difficult.
Because they are variations of the same color, it is not always easy to see if the color that is falling is the same shade as the piece down there.
So it takes a lot of skill and a sense of observation in this challenge.
The game is compatible with both iPhone and iPad and can be downloaded from this link.
