Normal 6x6 Sudoku rules apply. (ie place the digits 1 to 6, once each, in every row, column and 2x3 box). MINESWEEPER: Shade some cells ('mines') and leave the others unshaded ('cleared'). Two cleared cells are shown (although one of these still needs its digit to be entered). Each digit in a cleared cell indicates how many mines are in the (up to 8) surrounding cells. No two 2x3 boxes have the same number of mines.
