I saw a trivia game where you answered questions about Christmas and at the end of the game you got a tree decoration for every answer that was correct. In that game there were lots of questions to decorate the Christmas the tree. I tried to make a similar game in Scratch with books. I scripted 5 rounds, so the most you can fill is 5 books on the shelves. Less than 5 and you'll know that you chose incorrectly. If you wait at the end of the game you will see 10 books on the shelves. The first 5 was enough to give you the idea of the game, I'll code the other 5 books at a later time.
