Saturday Special – Non-consecutive Butterfly Sudoku
After a few weekends without any special puzzles, now I present you with another Gattai-4 non-consecutive Sudoku puzzle. This time, it’s a (somewhat forgotten) Butterfly Sudoku variation. The 4 sub-puzzles heavily overlap, so be careful!
Non-consecutive Butterfly (Gattai-4) Sudoku for Saturday, May 10, 2008. Difficulty: Brain
Rules: Solve the puzzle so that any two horizontally or vertically adjacent cells DO NOT contain two consecutive numbers (1 and 2, 2 and 3 and so on to 8 and 9). All other standard overlapping Sudoku rules apply.
