Chess Puzzles
Solve tactics from real games. Your rating adapts as you go, no signup needed.
How the puzzle trainer works
Every puzzle is a real position from a real game, not a hand-picked textbook example. Solve the correct move (or line) and your rating goes up; miss it and it goes down, the same expected-score math chess rating systems use. You start at 1200 and the puzzles get harder or easier to match you, so the trainer stays challenging whether you are a beginner or an expert. No account needed, your rating and streak are saved in your browser.
Why tactics training matters
Most rating points below the master level are lost to missed tactics, not bad opening theory or subtle endgame technique. Drilling forks, pins, skewers, and mating patterns until you spot them instantly is the fastest way to stop losing games to one-move blunders. If you already know which mistakes you tend to make, you can also analyze your own games and Chesslume will turn your actual blunders into puzzles built from your own play. For more on why raw engine output is not enough on its own, see how to review your chess blunders.
Frequently asked questions
Are the puzzles free?
Yes. Unlimited puzzles, no daily cap, no signup, and no premium tier.
Where do the puzzles come from?
They are pulled from a large database of real tactical positions from real games, each tagged with a difficulty rating and a theme like fork, pin, or mate in two.
How does the rating work?
It is an Elo-style system: solving a puzzle rated above you gains more points than solving one rated below you, and the pool adapts to keep serving puzzles near your level.
Do I need an account to track progress?
No. Your rating, streak, and solved count are saved locally in your browser, so they persist between visits without a login.
What is the difference between this and the game analyzer?
The game analyzer reviews a full Chess.com or Lichess game and grades every move. The puzzle trainer is standalone tactics practice, though when you analyze your own games, Chesslume can also build puzzles directly from the mistakes it finds in them.
