About Rounds
Rounds is a daily-puzzle study tool for students preparing for their medical board exams (ie USMLE/COMLEX). Each day brings a small set of board-style games — a Connections grid, a Mini crossword, and an Arrows physiology round — designed around active recall and quick daily reps.
The three formats hit different muscles: Connections trains you to see the category behind a list of look-alikes, the crossword rewards precise vocabulary, and Arrows drills the cause-and-effect physiology that boards love to test. Miss a day? The archive keeps past puzzles around for extra practice.
