I attended the Ga Tech Full Stack Developer Boot Camp, and as part of the course I had to create a few fun websites as homework assignments. Here are two of the sites I've made:
The Trivia Game has 23 questions, and you're given thirty seconds to answer each question. I do NOT display the correct answers and I do NOT tell you which questions you answered incorrectly. I chose to do this to make the game more challanging. As the instructors at the Tech coding boot camp say, "Google is your friend."
The Hangman Game uses the names of musical groups / artists as the words and phrases you will try to guess. The list of artists and groups is quite eclectic. You might find that you enjoy some of their work. Again, "Google is your friend."
