Sudoku Islands

Category: Sudoku variations

Sudoku Islands takes regular 9 x 9 and adds in the Island twist. Just like in a regular Sudoku puzzle, the digits 1 - 9 each appear exactly once in each row, column and 3 x 3 box. On top of each puzzle grid you’ll also see four “Islands” floating. Each Island also has 1 - 9 appearing uniquely in each of its nine grey squares.
