In addition, the digits in each inner shape (marked by dots) must add up to the number in the top corner of that box. No digit can be repeated within an inner shape.  \nExample  \nWe’ve provided a detailed explanation on the pages that follow, but here are some general tips:  \nExamine this section of a Killer Sudoku puzzle. Don’t let the empty grid put you off. Look for sum boxes with very high and very low totals. They’re likely to provide a limited choice of contents.  \nRemember that the numbers in each row, each column and each 3x3 block must always add up to 45. (1+2+3+4+5+6+7+8+9=45 .) See the tinted block above. The numbers in the block add up to 50. Notice that one of the inner boxes extends beyond the block by one cell. The number in this, the bright yellow cell, must be 50-45. In other words, 5.  \nUse your Kakuro skills to identify sum boxes that have unique digit answers. For example, the 16 above can only be filled with a 7 and a 9. See the table on the final page for details.  \nLook for unusual sum box shapes. They often lead to a square that’s easy to complete.  \nFinally, don’t forget the basic rules of Sudoku. It’s easy to get tangled up in sums when the standard rules will get you there.  \nKILLER SUDOKU  \nSolving Killer: a guided tour  \nIf you are new to Killer Sudoku, we recommend that you work through this easy-to-follow step-by-step guide to solving a puzzle. It provides the perfect introduction to the techniques that can be employed to tackle this, the king of Sudoku puzzles.  \nKiller Sudoku puzzles may look intimidating, but don’tbe put off by the empty grids. The puzzles follow the rules of normal Sudoku – place a digit from 1–9 so that each row, column and 3x3 block contains all of the digits from 1–9. In addition, the digits in each inner shape (marked by dots) must add up to the number in the top corner of that shape. No digit is repeated in an inner shape.  \nStart by looking for sums that use unique combinations of digits. In the top row of the grid above, the 17 in the right-hand block can only be made up of 8 and 9. Similarly, the 4 in the top row of the centre block can only be made up of 3 and 1. It can’t be 2 and 2, as digits can’t be repeated within a shape.  \nUse these unique combinations to narrow down the possibilities. In the second row there’s a 16 in the centre block, which can only be made up of 7 and 9. The 17 in the third row can only be made up of 8 and 9, and as the centre block already contains the 7 and 9 from the 16, the 9 must go in the left-hand block.  \nDon’t forget the basic rules of Sudoku – it’s very easy to get tangled up in the sums. For example, the first and third rows of the above grid already contain 8, in the centre and right-hand blocks. The 8 must therefore be in the second row of the lefthand block. It can’t go in the third box so the 14 in the first and second boxes must be made up of 8 and 6.  \nThe 3 shape in the centre column at the bottom of the grid must be made up of 1 and 2. The 1 for the 4 shape in the first row must therefore be placed in box A, as it can’t go in the centre column. The 1 for the 3 shape in the fourth row must then be inbox B. The 1 in the centre block must be in the third column. It’s too small to make up the 22 or 13 shapes, so it must be part of the 7 shape in box C.  \nWith 2 being placed in the fourth and fifth rows, its position in the sixth row must be in box D, as it’s too small to make up the 14 or 22 shapes. The 23 shape in the central column has a unique answer of 6, 8 and 9, so the 16 shape in the top centre block must have the 7 in box E.  \nThe total number of digits in each 3x3 block always adds up to 45. In the bottom left-hand block, the shapes extend outside the block by one box. Add up the shape totals covered within the block (14+7+8+14+7)=50 . Subtract 45 to work out the digit in the box outside the block – in this case 5 in box F. Complete the 14 shape with a 9.  \nThe 8 shape","cbCaiqqI4YicqAEf","https://ap.wps.com/l/cbCaiqqI4YicqAEf","pdf",218306,"English","# Killer Sudoku\n## Normal rules plus inner-shape sum constraints\n## General tips for solving\n## Guided tour: step-by-step technique flow\n## Unique digit answers and sum-box reasoning","[{\"question\":\"What extra rule makes Killer Sudoku different from normal Sudoku?\",\"answer\":\"In each inner shape marked by dots, the digits must add up to the number shown in the top corner of that box, and no digit can repeat within the same inner shape.\"},{\"question\":\"How do you use the standard Sudoku total of 45 in Killer Sudoku?\",\"answer\":\"Each 3x3 block contains digits 1–9 exactly once, so the block always sums to 45.
