Found this gem, "Guess the Correlation", via the subreddit r/statistics. The redditor who posted this resource (ow241) appears to be the creator of the website. Essentially, you view different scatter plots and try to guess r. Points are rewarded or taken away based on how close you are to true r. The game tallies your average amount of error as well. It is way more addictive than it sounds. I think that accuracy increases with time and experience.
I think this is a good way for statistics instructors to procrastinate. I think it is also a good way to help your students build a more intuitive ability to read scatter plots and predict the strength of linear relationships.

| True r for this one was .49. I guess .43, which isn't so bad. |
