The rules in short
- Place a digit
Place a digit
Put a piece on a closed cell. The right digit opens it. With a wrong digit, the piece sits out for the rest of the board. A mine blows up the piece, whatever its digit, and costs a life.
- Flag and pass through
Flag and pass through
Flag a cell you think hides a mine. A rook or bishop that runs through the flag defuses the mine. If there was no mine, the piece stops on a question mark, sits out, and you lose 10 points.
- Read the sensors
Read the sensors
Every piece on the board shows a number. A white piece counts the mines in its zone. A black piece counts the closed cells in its zone that hide its own digit.
One board a day
Daily #1 in the train car: a rook opens a cell and runs through a line of flags, defusing the mines under them. Two probes find the last ones, and the train pulls into the station.
Everyone plays the same 6×6 board, one try each. A new board comes out at midnight UTC.
Defuse every mine to win. The result card keeps your streak and gives you a grid to share.
