SECOND VERSION
First, we will decide what kind of game we want to play. In this case, we have opted for a game of questions and answers (quiz game).
Then, we program the game in mBlock Software:
If user answer correct, it adquires one point, and mBot run forward during 3 seconds. In the other case, if user answer wrong, it adquires one mistake and mBot run backward during 0.5 seconds.
Once we have programmed the game, we must match a mBot to a computer, and the other mBot to the other computer.
Also, with a rope, match one mBot with the other.
