00:00:00 - 00:45:00

The new rules in Sudoku can help to solve the puzzle more quickly and easily. One rule is that if a number cannot be doubled, it must be a double. Another rule is that if a number is a seven pair, it must be doubled. These rules can help to disambiguate the order of the squares in a particular cell, and help to solve the puzzle.

• 00:00:00 The rules of this puzzle state that blue lines must have the same sum in each region entered by the line, and that cells visited by the line must have the same sum as the cells visited by the blue line. For example, the blue line in the image goes into box five and visits five cells there. The yellow cells in that box must have the same sum as the blue cells, or 255, and the blue cells in box two must have the same sum as the yellow cells, or 65.
• 00:05:00 In Sudoku, certain cells must sum to a certain number, but this sum is not always easy to calculate. Regions in the grid can help simplify the sum, but there are also complications involving doublers. In the video, a new rule is presented that can complicate the sum even more.
• 00:10:00 This video discusses how the new rules in Sudoku can help solve the problem of having two zeros on a line. The new rules allow for one of the digits to be doubled to get around the problem.
• 00:15:00 The best new rules in Sudoku involve making sure that a number in a cell counts as a two or three, in order to make the total for the middle box add up to 15. The video discusses a problem that can occur when the number in a cell does not count as a two or three, which would result in the cell counting for a 10.

• 00:25:00 In this video, the best new rules for Sudoku are introduced. These rules include the use of double digits, foreign squares, and the use of two-by-two combinations. The rules help to disambiguate the order of the squares in a particular cell, and help to solve the puzzle.
• 00:30:00 The new rules in Sudoku allow for more progress in solving the puzzle. If a six is present, it is not doubled and cannot be combined with seven or four to create a nine, which results in a different maximum value. If the six is combined with three or four, it becomes a 15.
• 00:35:00 In this YouTube video, the best new rules for Sudoku are explained, including the elimination of the 1-7 squares, the use of numbers already found in the puzzle, and the need for a double digit in order to be doubled.
