Remember this when Windows first came out? Whether you do or don't, here it is again.
You have to clear the mines in the grid by working out where they are... a bit like battleships. Watch out though - it's addictive!
Our puzzles are unique to this site, so you won't find them anywhere else. We think they're pretty hard too.
Solutions will be available the following day!
For those of you who don't know Sudoku, the puzzle is a 9x9 grid of cells, which is also separated into 9 grids of 3x3 cells. The object is to fill in numbers from 1 to 9 so that every row, every column and every subgrid has numbers 1 to 9 in it only once i.e. you can't have the same number twice in any row, column or subgrid.
