chess.com just released a new feature, Puzzle Rush, in which the user gets 5 minutes to complete as many puzzles as possible with increasing difficulty. Two errors are allowed, and the third mistake ends it. It's addictive and a lot of fun, with hourly / daily leaderboards, but free users there only get one access per day.
