NGChess (ngchess.com), by Next-Gen Chess, is free, browser-based chess built around one simple idea: you should learn while you play, not just after you lose. In games against the computer a chess engine grades your moves from Brilliant to Blunder and shows your live win probability, and the coach points out, in plain language, hanging pieces, missed captures and mate-in-one. There's nothing to download and no account required to start.
What makes it different
A coach in every game
In games against the computer: engine-graded moves (Brilliant → Blunder), a win-probability bar and Stockfish hints, plus plain-language notes on hanging pieces, missed captures and mate-in-one.
A searchable patterns library
Explore openings, defenses, checkmate patterns and tactics with move-by-move boards, key ideas, and strengths & weaknesses — then play any of them against the computer.
Custom chess
Build custom boards up to 16×16 in the free Chess Lab, place the pieces anywhere, and invent your own variant — then play it pass-and-play on one device. (The standalone board editor supports up to 12×12; the computer opponent plays standard 8×8 only.)
Game review & training
Import any game for a move-by-move review, sharpen tactics with an adaptive, spaced-repetition trainer, and solve the daily puzzle.
Safe by design
No chat with strangers and no public matchmaking. In classrooms, students join with an alias — no email, password, or personal profile required.
Accessible to everyone
A colorblind-safe board, dyslexia-friendly font, larger-text mode, keyboard support and screen-reader labels — built toward WCAG 2.2 AA.
Built for classrooms and clubs
Clubs and academies get one connected workflow: a public program page with registration and waitlist requests, enrollment straight into a class students join with a code and an alias, puzzle assignments with due dates and per-student progress, and a full-screen projector board for teaching. Teachers can also run private classroom tournaments for practice — Swiss pairings a round at a time, results entered by the teacher, and printable certificates. Because students play with aliases and never chat with strangers, it's a setup schools can review with confidence.
Who it's for

Whether you're learning your first opening, reviewing last night's game, teaching a class of thirty, or inventing a brand-new variant on a 10×6 board, Next-Gen Chess is designed to help you understand the game a little better every time you play.
