About Chessle

Chessle takes Wordle's colour clues and applies them to the opening moves of a chess game. Each day's puzzle is a numbered, named opening, such as the Queen's Gambit Accepted, Classical Defence. You enter a guess by making the moves on a board, alternating White and Black, and submit the whole line.

Every move in your line then gets a colour. Green means that move was played at that exact point. Yellow means the move is in the opening, but at a different point. Grey means neither side played it. You have six guesses. Normal mode asks for the first six moves; expert mode asks for ten and uses the opening's fuller name. You can also choose whether moves must match exact notation or just piece and square.

After you finish, the game shows what share of players solved that day's opening and how many tries they needed on average. A Chessle Infinite mode offers more openings to practise. Chessguessr, a similar game about real game continuations, describes itself as like Chessle but for whole games.

It suits chess players who know their openings, and anyone who wants a short daily way to learn the main lines.

How to play Chessle

1. Open Chessle and choose normal or expert mode.
2. Play a sequence of opening moves on the board for both sides.
3. Submit the line and read the colours: green right place, yellow wrong place, grey not played.
4. Adjust the line and try again, up to six guesses.
5. See how other players did, and share your result.

Tips

• Start with a common, flexible line such as 1.d4 d5 or 1.e4 e5 to test the first moves.
• A yellow first move often means the moves are right but in a different move order.
• In expert mode, the full opening name hints at the later moves.
• Practise in Chessle Infinite to learn the lines that come up.
