How Chess411 works
The next move calculator runs Stockfish 18 directly in your browser, so the position never leaves your device and there is no queue to wait in. Game review runs on our own engine server, which is why a full game comes back scored in seconds rather than minutes.
There is no account, no email capture and no daily cap on any of it. Your streak, your board style and the rest of your preferences live in your browser on your own device.
Every puzzle on the site came out of a real game, not a composed study. Each one carries a rating from 400 to 3000 and a set of theme tags, so you can aim straight at the tactics you keep missing.
The Daily Puzzle Challenge hands every player the identical set each day, which is what makes a shared score worth comparing. A new set arrives at midnight, your local time.
Common questions
Is Chess411 really free?
Yes. Every tool on the site is free, with no account and no daily caps. There is no paid tier holding back the good features, and nothing on the site is metered.
Do I need an account?
No. There is no sign-up anywhere on Chess411. Your daily challenge streak, board style and other preferences are stored on your own device, so you can start playing straight away.
What is the Daily Puzzle Challenge?
A daily run of puzzles that is the same for every player, starting easy and getting harder as you go. You have three lives, one attempt per day, and the clock runs while you solve. Finish it, share your result, and keep your streak alive. A new set drops at midnight, your local time.
Can I review my own games?
Yes. Game review fetches your recent games from chess.com or lichess by username, or takes any pasted PGN, then scores every move with accuracy numbers and labels from brilliant to blunder. It is free and unlimited.
Which engine does Chess411 use?
Stockfish, the strongest open source chess engine there is. The next move calculator runs Stockfish 18 directly in your browser, and game review runs on our own engine server so a full game comes back in seconds.
Where do the puzzles come from?
From positions that actually happened in real games, not composed studies. Each one carries a rating from 400 to 3000 and a set of theme tags, so you can train the tactics you keep missing.
