Fair play: every click is meant to be counted by the server, not the browser, and anyone clicking faster than a person can sustain stays in the game but is left off the leaderboard. The speed check on this device marks a session as not ranked at 600 or more clicks in a minute, or 1,200 or more in degen mode, where two thumbs can go faster, and spree medals stop counting. Only signed-in players appear on the leaderboard, and display names are checked before they go up.
