What is Boardle?

Boardle is a daily chess puzzle game that requires you to guess the best move sequence for both sides in algebraic notation. The positions are sourced from lichess. Four difficulty sizes are available at the top of the page: Mini, Boardle, Mega, and Maxi. The standard August 25 grid displayed five moves per row across five answer rows.

How to play Boardle

  1. Select your difficulty size from the bar above the board: Mini, Boardle, Mega, or Maxi.
  2. Compose the move sequence on the chessboard. Entered moves appear as algebraic notation tiles, alternating between both sides.
  3. Use the « ↻ undo » button to correct moves before completing the line.
  4. Fill the entire line, then press « submit ». Tiles receive color feedback only after submission.

Reading the color feedback

The color code applies to complete moves. Green means the move is correct and in the correct position. Yellow means the move appears in the solution but belongs elsewhere. Gray means it does not appear in the solution at all. Notation must be exact: check symbols, capture marks, and mate indicators are included in the comparison, so a move counts only when its written form matches precisely.

The notation requirement

Algebraic notation is required. You should be able to read and write chess moves in standard notation before playing. Tiles fill automatically in this format, and the game compares them strictly. For example, writing a simple check instead of a mate is treated as a different move. Players who need a reference can follow the notation tutorial linked in the instruction panel.

Available modes

The standard Boardle grid required five moves per line across five answer lines on August 25. Boardle Mini offers a shorter version through a link above the board. Boardle Mega and Boardle Maxi represent the third and fourth size options. The survey did not open these alternative sizes, so their specific grid dimensions are not documented here.

Strategy tips

You must play for both sides. The solution includes the best opposing defense, not only your attacking moves. A yellow tile that shows a move present but misplaced is the most useful feedback: the move is correct, but the sequence order needs adjustment. Check the position carefully before submitting, since each line receives feedback only after completion. If you are not fluent in reading written move sequences, open the notation tutorial before starting your first game.
