Blunders Daily

The Blunders daily challenge is a single chess puzzle published at midnight UTC — every player in the world gets the same position on the same day. Solve it in as few tries as you can: a move found on the first attempt scores green, a move that needed a retry scores yellow, and a revealed solution scores red. Your finished grid becomes a shareable result, and solving day after day builds a streak worth protecting.

When one puzzle isn't enough, the rest of Blunders is a full training ground: thousands of free puzzles across every tactical theme, and free opening guides with machine-verified main lines and traps. A free account keeps your daily streak safe across devices — and when you're ready to go deeper, Blunders analyzes your own games and turns your real mistakes into training.
