Every Thursday, Apple chooses an iOS app or game as its own Free app of the week.
This time, the one selected was the game Colorcube developed by Next Apps.
Here's what Apple says about it:
Colorcube is not your usual puzzle game. On a relaxing background music, arrange geometric pieces, and change and mix their colors to try to reproduce a particular look. Minimalist, addictive and aesthetic, Colorcube offers more than 250 puzzles: enough to occupy the brain for long hours!
Colorcube usually costs $ 1 and is free for the first time. Enjoy! 😃
