Logic Masters Deutschland e.V.

SUDOKU RULES: Fill the grid with digits 1 to 9, so that each digit occurs exactly once in every row, every column and every 3x3 box. KILLER SUDOKU: Numbers given at the corner of each colored cage indicate the sum of all digits inside the cage. No digit may be repeated within a cage. THERMO SUDOKU: The digits in the thermometers must be strictly increasing in each cell from the bulb/reservoir to the end. ARROW SUDOKU: Digits in a circle should equal the sum of all digits on the arrow leaving that circle. Two cell circles should be read from left to right (e.g. 1-3 = thirteen). Digits may repeat along an arrow. LITTLE KILLER SUDOKU: Little killer clues outside the grid indicate the sum of the digits along the diagonal. Digits may repeat along the diagonal.
