Flow Chart

- Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Palindromes: Digits along a palindrome line read the same forwards as backwards along the line. - Column Indexing: Digits placed in red cells indicate the position of the corresponding column number in that row. For example, if r2c1 were a 6, then r2c6 would be a 1. - Row Indexing: Digits placed in green cells indicate the position of the corresponding row number in that column. For example, if r2c3 were a 6, then r6c3 would be a 2.
