RankPlayerGatesSRSolved

The blunder training leaderboard for Blunderer, the free chess tactics trainer, ranked by puzzle rating (shown after each name). Harder puzzles are served to higher-rated players, so rating is the fair measure. You need 20 rated puzzles to appear. Badges unlock by puzzles solved: dinosaurs from Brontosaurus (start) to Tyrannosaurus rex (10,000 solved). Gatekeeper monsters guard every 200 points from 800 to 2800: while a gatekeeper lives, nobody below it can climb past its gate without beating it, and the winner keeps it as a trophy. A killed monster stays dead for 30 to 60 minutes (the gate is open), or only 2 to 5 minutes if its killer had already killed another gatekeeper in the past 2 hours (1 to 3 minutes if that killer is clearly underrated: a brand-new account, or up 300+ rating in 2 hours), then a brand-new monster spawns.
