Logic Masters Deutschland e.V.

Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.

Equalines: On each line the digits add up to the same total that has to be determined by the solver. Digits may repeat on a line if allowed by sudoku rules.

Doubler: There is exactly one doubler in each row, column and marked 3x3 box. The nine doubler cells have to contain a complete set the digits 1-9. Doubler cells contribute twice the value of the digit in that cell to line totals.

Have fun solving!
