Kids quickly get bored with everything, and my son is not an exception. He was tired of Minecraft after one week only.
Fortunately, I managed to get him interested in Scratch and ScratchJr.
Scratch is a bit more complicated, while ScratchJr is very simple and intuitive. My son figured it out on his own in half an hour.
At the same time, I decided to use educational games, so that there would be some variety and the child would not lose interest.
Ducksters helped me with this. Its Math Games and Puzzle Games are really interesting.
