Play Rookie

5 fixed levels, Private through General, each a real fixed challenge, not a rating match. It runs entirely in your browser using Stockfish's own strength-limiting settings, not a separate weaker engine, which is why it still plays like real chess rather than making random bad moves to stay easy.

This is meant as a practice partner, not a claim about your real rating, there's nothing here that affects your actual Chess.com or Lichess rating. Beat a level once and it's yours for good, even if you lose a rematch, so you can always come back and try again without losing progress.
