Bouncing X-Sums Sudoku by clover!
(This post is part of the Genuinely Approachable Sudoku (GAS) series.)
In this unusual variation of X-Sums Sudoku, the X-Sums path bounces off the border cells and rebounds into the inside of the grid if it extends too far.
or solve online (using SudokuPad)
Theme: Bouncing Baby Puzz
Author/Opus: This is the 118th puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.
Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Also, the clues outside the grid indicate the sum of the first X numbers placed in the corresponding diagonal direction, where X is equal to the first number seen in that direction. If the sequence of X numbers extends to the edge of the grid, it “bounces” at a 90-degree angle off the center of the edge cell and continues back towards the interior. (For example, because of the 9 clue to the right of R3 and because R2C9 = 3, R2C9 + R1C8 + R2C7 = 9.)
