Set up a position

Write a piece letter in a square (K Q R B N for white, k q r b n for black) and a moment after you stop it fades into the piece; keep writing before then to change it. Tap an empty square for a pawn of the colour you used last, twice for the other colour; tap a piece to switch its colour, twice to remove it. The FEN is written for you. More.

FEN

Play from here

Uppercase is white, lowercase black: the letters FEN uses. The recognizer reads only piece letters here; a second after your last stroke the piece it reads fades in over the ink for a second and is then set, and the runners-up stay tappable for a moment if it read the wrong case.

Your handwriting is recognized on your device: nothing you write is sent anywhere. Handwriting recognition by millirec.
