A chess board that just loads.
A short page about who runs this site, why it exists, and what we think a chess game on the internet should feel like.
Why this site exists
Most chess sites are doing one of two things: trying to sell you a subscription, or trying to keep you scrolling. Both are fine — they pay for serious infrastructure and titled-coach content. But neither helps the person who just wants to play a game of chess right now, in the next ten seconds, without making an account.
Unblocked Chess is for that person. The board is on the homepage. You open the tab, you play, you close the tab. That's the entire product.
What we believe
Chess should be free. Not freemium. Not "free with sign-up." Free in the way a public chess board in a park is free — you walk up, you sit down, you play.
The board is the product. Everything else on a chess website is decoration. We spend our effort on making the board fast, the AI fair, and the rules correct.
No dark patterns. No pop-ups asking for your email. No "are you sure you want to leave" prompts. No notifications you have to dismiss. The site is what's on the page.
How the AI works
The single-player opponent isn't Stockfish or a neural network — it's a lightweight negamax engine with alpha-beta pruning and a piece-square evaluation table. It runs entirely in your browser, which means it works offline once the page loads and doesn't send a single byte about your moves anywhere.
At Beginner level it intentionally plays a percentage of random moves so newer players have a chance to win and learn. At Expert level it looks three moves deep and orders moves by capture value, which is enough to punish loose play without making the game feel impossible.
Who's behind the site
All the educational content here is written in-house rather than outsourced or syndicated. Because the author is a web professional rather than a strong player, accuracy is handled by verification instead: every puzzle is confirmed by a chess engine before it is published, and the board diagrams are generated by playing the listed moves through that engine rather than being drawn by hand. The full method is documented here.
How we keep the lights on
The site is supported by display advertising — small, unobtrusive ad units placed where they don't interfere with the game or the reading experience. We don't sell your data, we don't run pop-ups, and we don't have an affiliate program pushing you toward subscriptions.
If the ads ever feel intrusive, that's a bug. Tell us about it on the contact page and we'll fix it.
Editorial policy
Every educational article on Unblocked Chess is written from direct playing experience and reviewed for accuracy against established chess principles before publication. We cite the standard sources when we describe theory — opening encyclopedias, endgame tablebases, and well-known instructive games — but we put everything in our own words.
If you find a mistake in our content, please tell us. Errors get fixed within 48 hours.
