I made an awesome Kahoot for reviewing the concepts of weathering, erosion, and deposition. Kahoot is a game show style game. You need one computer to project the questions and possible answers, and you need a cell phone, iPad, Chromebook, or other device to input the answers. This is best played in a classroom setting, where everyone has devices to answer the questions, and the students get to compete with one another. There are points for correct answers, for faster correct answers, and for getting multiple answers correct in a row.
Disclaimer: This was my first Kahoot, and I created this before I paid attention to the importance of documenting the sources of the images used.
