Someone mined this sudoku. The rook has volunteered to go first.

Play Daily #1

Two pieces from the hand open closed cells, three flags go up in a row, and a rook runs through all three, defusing the mines under them and opening the cells
  1. Oh, a visitor! We're the knights. I'm the white one, I count mines.
  2. I count my own digit. Somebody has to.
  3. Still reading? That rook has already run through three flags and lived.

The short version

  • Place a digit

    Place a digit

    Put a piece on a closed cell. The right digit opens it, a wrong one benches the piece for the rest of the board, and a mine blows up whatever digit you brought.

  • Flag and pass through

    Flag and pass through

    Raise a flag where you suspect a mine. A rook, bishop or queen running through it defuses the mine; if there was none, the piece stops on a question mark and you lose 10 points.

  • Read the sensors

    Read the sensors

    Every piece on the board shows a number. White counts the mines in the closed cells it attacks, black counts the closed cells there that hide its own digit.

All the rules

One board a day

Everyone plays the same 6×6 board. A new one lands at midnight UTC, and you get one go at it: a lost board is lost for the day. Defuse every mine to win. There is no clock; your score goes on the result card in pawns.

Finish and you get a grid of squares to paste anywhere: what stayed closed, what you opened, the mines you defused and the ones that blew up, and your score:

Come back the next day and the card keeps count of your streak.
