Someone 😉 complained and asked for more new variants and specifically for cons/non-cons puzzles. So here it is – first ever Consecutive Butterfly (4 in 1) Sudoku puzzle. “Pipes” (“|” symbols) between cells mean that those cells must contain consecutive numbers. If there is no pipe – those cells can’t contain consecutive numbers. This second […]

If you have seen Sudoku puzzles with this layout before – please let me know! There are 5 puzzles that heavily overlap each other – in fact the center (inner) grid is completely covered by the […]
