• Normal sudoku rules apply.
• Digits on the hour and minute hands (thermometers) increase from the center outwards.
• The second hand (gray line) contains digits in order with a constant difference (e.g. 3-6-9, 5-4-3 or 7-7-7).
• Digits separated by a white dot (diagonally) are consecutive (not all white dots are given).
• Any digit in one of the four corner circles has to appear in one of the four squares around that circle.
• Antiking : Diagonally adjacent cells must contain different digits.
