About Chessguessr

Chessguessr is a Wordle for chess games. Each day it takes a position from a real game between two named players, with their ratings shown, and you enter the next five moves as they were actually played. You are not looking for the best line, only the one those players chose, which makes it a puzzle about reading a game as much as calculating.

After you submit a line of five moves, each tile is coloured. Green means that move was played at that point. Yellow means the move appears in the played line but at a different point. A third colour means the same type of piece moved there, but the move itself is wrong, for example a different knight move. Notation has to match exactly, so a capture with check is not the same as the capture without it. You keep refining the line from the clues.

The position is numbered and dated, the same for everyone, and a new one appears every day at midnight UTC (puzzle 1564 fell on 2 October 2026). The site credits its maker as Assios, and the code is public on GitHub. It suits chess players who like guessing what a human would play, and Wordle players who know enough chess to read a position.

How to play Chessguessr

1. Open Chessguessr and study the day's position and whose move it is.
2. Enter five moves in a row, alternating sides, by moving the pieces on the board.
3. Submit and read the colours for each move.
4. Keep the green moves, move the yellow ones to other slots, and try new moves elsewhere.
5. Find the exact five-move line, then share your result.

Tips

• Start with forcing moves: captures, checks and recaptures are often what humans play.
• Watch the notation; a check symbol makes the move different in the game's eyes.
• A piece-type hint tells you which piece moved, so list that piece's legal moves.
