The challenges in this feature give you the chance to think about possible solutions in different ways.

Along with the Five Coins task, we are introducing you to a variation of the well-known Sudoku, by including mathematical clues which challenge you to apply your knowledge of the four operations. For each grid size, there are four different puzzles, at each of three levels of difficulty, so plenty for you to get stuck into!

To introduce the Mathdokus, and to give a flavour of the kind of strategies that you may find useful, you may like to watch this video.
