Whilst Carol Vorderman may irritate everyone in the room with her constant Sudoku-based wittering, the game itself is actually quite enjoyable. Those of use who prefer to spend our time with others, though, might find its solitary nature a little off putting. But not any more, thanks to our Sudoku board game for 2-4 players.

The object of the game is to solve mind-bending number puzzles and enter the solutions in the boxes on the board. You have 30 seconds to solve the puzzle – if the time runs out before you've entered your answer, you lose your turn. The winner is the player with the highest total after all the numbers they've entered have been added together. Addictive, challenging, and now with added people. Brilliant!
