4 x 4 Under The Sea Sudoku
Our oceans cover over 70% of the Earth's surface. Of all the habitats on Earth the oceans hold the most mystery. While we are aware of hundreds of thousands of marine life forms there are still many more still to be discovered.
It's under the sea "fish" Sudoku - fill in the grid with the letters F, I, S and H, making sure no letter is repeated in every row, every column and within each mini grid.
