Guess the Opening

From Repertoire Builder

Location: Puzzles > Guess The Opening

The Guess the Opening puzzle is a chess take on Wordle: you start from an empty board and reconstruct a complete opening line from your repertoire. Enter your moves in sequence, submit your attempt, and use the concise feedback to refine your next try.

This puzzle helps you to:

  • + Strengthen long-term recall through full-sequence reconstruction from memory.
  • + Improve precision in move order and pattern recognition across your openings.

You can choose how many moves to play and which colour to play from; this determines which of your repertoires (White/Black) the line is sourced from. Click New Game to generate a fresh challenge, then enter your moves directly on the chessboard.

After completing the line, click Guess to check your attempt:

  • Green — the right move in the right position.
  • Orange — a move from the line, but in the wrong position.

You have up to 6 attempts to complete the full line. Use the controls to manage your run:

  • Clear: Reset the board and your current guess.
  • Autocomplete: Fill the line with the correct sequence (useful for quick review).

When finished, use the button to open the current position in your Repertoire Builder for deeper study and context.
