Chessle: Guess the Chess Opening
Name the opening moves for White and Black in six tries, with green, yellow and grey tiles after every guess.
How to play Chessle
Pick a mode and type the opening
Choose Normal (three moves per side) or Expert (five per side). Then type the moves in standard chess notation, White first, and submit the row. Pawn moves need only the square, like e4. Pieces start with a capital letter, like Nf3.
Read the tile colours
Green means that exact move was played on that exact turn. Yellow means the move is in the opening, just in a different slot. Grey means neither side played it. A yellow d4 on White's first move tells you d4 belongs somewhere else in the line.
Refine your line within six tries
Keep the greens where they are, move the yellows to new slots and drop the greys. A full row of green solves the puzzle and reveals which opening you just rebuilt.

What is Chessle?
Chessle is a free daily puzzle for anyone who has ever argued about how a chess game should begin. Each puzzle hides a real opening line. Your job is to rebuild it by typing the moves for both White and Black, one turn at a time.
Instead of guessing a single word, you guess a short sequence of moves. That makes Chessle feel closer to replaying a game from memory than to a vocabulary test, and it works for casual players and club regulars alike.
How Chessle feedback works
After each guess, every move gets a coloured tile. Green is a perfect hit: right move, right turn, right colour. Yellow is the interesting one, because it proves the move is part of the answer while ruling out the slot you tried. Grey clears a move from your shortlist completely.
Because both colours are in play, Chessle rewards thinking in pairs. A yellow on Black's second move can be the clue that unlocks White's third.
Normal or Expert mode
Normal mode asks for three moves per side, six moves in total, which is enough to separate many well-known openings. Expert mode stretches the line to five moves per side. Pick the length before your first guess, because the hidden answer matches the format you choose.
Normal is a good quick daily habit. Expert suits players who enjoy sidelines, early trades and unusual move orders.
Tips for solving Chessle faster
- Open with a mainstream line such as e4 e5 Nf3 Nc6. Even a row of yellow tiles narrows the field.
- Treat yellow as a promise: the move is in the answer, so test it in a different turn next time.
- Don't repeat a grey move. If Nf6 is grey, stop spending guesses on that knight jump.
- Think about what usually follows. If d4 is green for White, ask which replies Black plays most often.
