Play Chess Against Computer — Free, No Sign-Up
Play chess against the computer at any level, free: a full ladder of bots from 150 to 3200 Elo, each with its own country, style, and signature opening, powered by Stockfish 18 running in your browser. No account, no download, no daily limits — and every game ends with a free full game review.
Chess bots from beginner to unbeatable
Each bot plays at a fixed strength, so you always know what you're up against. The beginner bots make real blunders — hanging pieces, missed mates — while the 1500+ bots use Stockfish's own calibrated Elo limiting. Every bot has its own page if you want to jump straight into a game at that level:
- Milo — 150 Elo · Just starting out. Makes it up as he goes and loves every second.
- Bea — 250 Elo · Knows the moves, not the danger. Hangs pieces with a smile.
- Pia — 400 Elo · Just learned the rules. Hangs her queen and celebrates anyway.
- Tariq — 550 Elo · Quick and fearless. Grabs material first, asks questions never.
- Ben — 700 Elo · Plays in the park at lunch. Spots your threats… about half the time.
- Greta — 900 Elo · Careful and tidy. Punishes loose play, rarely takes a risk.
- Zara — 1000 Elo · Knows forks and pins. Still forgets her back rank exists.
- Ravi — 1250 Elo · Club regular. Punishes hung pieces, drifts in quiet positions.
- Elena — 1500 Elo · Solid club player. You will need a real plan, not just tricks.
- Kenji — 1650 Elo · Systems player. Sets up the same clean structure and outplays you from it.
- Viktor — 1800 Elo · Tournament veteran. Converts small edges with zero mercy.
- Mei — 2100 Elo · Expert strength. One loose move and the game quietly slips away.
- Sofia — 2300 Elo · Fearless and dynamic. Trades structure for activity and makes it count.
- Nadia — 2500 Elo · Master level. Beating her is a story you get to tell.
- Bjorn — 2800 Elo · Grandmaster strength. Grinds any endgame until it cracks.
- Max — 3200 Elo · Full-strength Stockfish. Nobody beats Max. Draw and be proud.
How to play chess against the computer
- Pick your opponent. Choose a bot from 150 to 3200 Elo — from your very first game to full-strength Stockfish. Each is a character with its own style and signature opening.
- Set up the game. On the bot's screen, choose your side (White, Black, or random) and a time control — a preset clock, your own custom time, or no clock — or set up a custom starting position, then press Play.
- Play the game. Move by dragging or tapping. The bot replies in about a second, right in your browser.
- Review the game free. When it ends, one click gives you a full free game review — accuracy, blunders, and the moves you missed.
Finish the game, get a free game review
This is what makes playing here different: when your game ends, one click runs a full free game review — every move classified from Brilliant to Blunder, your accuracy and estimated rating, and an eval graph of the whole game. Play a bot, see exactly where you went wrong, then fix your mistakes — the entire improvement loop, free.
No download, no account, no limits
The engine is Stockfish 18 compiled to WebAssembly, running on your own device. That's why there is no sign-up wall, no ads between games, and no "3 games per day" meter — there's no server doing the work, so there's nothing to ration. It also means your games are private: nothing you play is uploaded anywhere.

Frequently asked questions
Is playing chess against the computer here really free?
Yes — every bot, every game, unlimited. The engine (Stockfish 18) runs in your own browser, so there's nothing to meter and nothing to pay for.
Do I need an account or a download?
No sign-up, no login, no app. Open the page and play. Your game is saved in your browser, so a refresh doesn't lose it.
How strong are the bots?
The ladder runs from Milo (150 — still learning the rules) to Max (3200 — full-strength Stockfish). Bots at 1500+ use Stockfish's own calibrated strength limiting; the beginner bots also make genuinely human-ish blunders so they're actually beatable.
Which bot should I play first?
Pick one about 100–300 points above your rating for a challenge, or at your level to practice technique. If you don't know your rating, start with Zara (1000) and move up when you win twice in a row.
Can I review the game afterwards?
Yes — that's the point. Every game ends with a one-click, free, unlimited game review: move classifications from Brilliant to Blunder, accuracy, and an eval graph. On other sites that's a paid feature.
