Are the puzzles checked?

Yes. Every position is generated and then checked by a full chess move generator, so at least one move is always checkmate.

Is there castling or en passant?

Not in these positions. They are built so that only ordinary moves matter.

Yes. The five puzzles are built from the date, so everyone gets the same ones.

Daily chess puzzles: White to move, find the checkmate in one. Five new puzzles every day, plus endless practice.

Mate in One

A real run of the game, recorded with captions and no sound.

Each puzzle shows a chess position with White to move. White moves up the board.
Tap one of your white pieces, then tap a highlighted square to move it.
If the move is checkmate, the puzzle is solved. If not, it counts as a miss and you can try again.
Solve all five puzzles of the day to finish the daily. Any checkmating move counts, not only the first one found. Practice gives endless extra puzzles that get harder.

Controls: mouse or touch. Made by CalcoTools.

List the checks first: most mates in one are checks.
Count the black king's escape squares, and see whether your move covers all of them.
Check that Black cannot capture the checking piece or block the check.
Look at the pieces defending each other: a queen next to your king can give a mate that is protected.
