Logic Masters Deutschland e.V.

Rules:

• Place the digits 1-9 once each in every row, column and box.
• The grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells.
• Clues outside the grid show the sum of the digits between 1 and 9 in that row or column.
• Digits along an arrow sum to the digit in the arrow's circle. Arrows don't cross or overlap and circles only contain single digits.
• Digits in a cage may not repeat and must sum to the total in the top-left corner of the cage.
• Digits in cells separated by X sum to 10.
