Normal Sudoku rules apply, except the numbers in the cells contained within grey lines add up to the figures in the corner. No number can be repeated within each shape formed by grey lines.

For a helping hand call our solutions line on 0906 200 83 83. Calls will cost £1.03 per minute, plus your phone company’s access charge. Calls from other networks may vary and mobiles will be considerably higher. Service supplied by ATS. Call 0330 333 6946 for customer service (charged at standard rate).

Buy next week’s Observer Digital Edition to see the completed puzzle.
