In the Going to the Movie game tree you need to figure out which friend you should call first to coordinate going to see a movie together. Since your friends are closer to each other than to you they will call the other friend to get them on board to see a film. However, they will only mention two types of films instead of three to influence what type of film you guys eventually agree to see.
In the Simultaneous Games Practice Sheet you will find two practice simultaneous games. First, Rock, Paper, & Scissors. Second, a random game. You can practice using dominant and dominated strategies to speed up the time to solve the random game.
