Finished Duolingo Chess, or another chess course? Most courses end the same way: you finish, and you're told to "graduate" to a big adult site. There's a calmer step in between — a free place to actually play, review, and go deeper, with no account, no ads, and nothing collected about you.
A course teaches patterns in isolation; games teach you to find them under pressure. Play a full game against a human-like opponent, then walk back through it and see the moment it turned — the single fastest way to improve once you know the rules.
Game review →The part courses skip and strong players never skip. Learn the handful of endings that decide most games, drilled to mastery with no stress timer.
Endgame trainer →You do not need to memorize twenty moves of theory. You need to understand why the good moves are good: develop, control the centre, keep your king safe. Openings taught as principles you can apply to any position.
Openings & principles →See more, further. Guess-the-move, board-vision drills, and calculation practice that build the skill a puzzle course only hints at.
Vision & calculation →Parents & pediatricians: how our chess is designed for calm, healthy play. Running a club or class? the free chess-club toolkit.
