Boardle is a free daily chess puzzle in the style of a Wordle game. You get five attempts to solve the puzzle by choosing the best series of moves for both players. As you play, your guesses will fill in the tiles below the chessboard using standard algebraic notation (SAN).
Once you've filled out all of the tiles, press the submit button. The tiles will change color to show how close your guess was to the solution.
A green tile means you made the correct move on the correct turn. A yellow tile means that move is in the solution, but it's not on the correct turn. A gray tile means that the move is not in the solution.
Note that a move only counts as correct if it has the exact right SAN. For example, Qxa8# is not the same as Qxa8. If you're confused about SAN, you can find out more by reading this chess notation tutorial.
