27 opponents, beginner to engine · 12,000 tactics puzzles, no daily cap · 4M games behind the opening explorer · 0 sign-ups required. Ever.
Every finished game gets the full treatment: ten move ratings from Brilliant to Blunder, accuracy for both sides, and a coach that explains any move you click — as many games as you like.
Every position shows real win rates and the most common continuations, built from rated games — side by side with the engine's own candidate lines. 1,914 openings, browsable without opening the app.
Twelve difficulty bands from 400 to 2800, a tactics rating that moves when you earn it, and Rush, Streak and a Daily on top. The cap other sites sell back to you simply is not here.
Make a room, send the link, play. No account for you, no account for them — the seat waits through disconnects, and the finished game lands in your library for review.
