Not sure puzzles really tell you anything about someone’s IQ. Seems doubtful, but okay. But yeah, puzzles, arcade games, dress up games, some sports games, all of that is a great way for me to switch off, take a break from work, or just kill some time. I especially like that now all of these are free and work right in the browser.
