It is a well established fact that we learn far more easier when involved in a fun and playful way! If we look at the massive popularity games like soduku have achieved we need to take some time out for our learners to engage in fun games that will also teach them to efforlessly do basic maths calculations with some logic thrown in.

One of these games are Calcudoku. “CalcuDoku are math based puzzles coupled with logic. Unlike other logic puzzles, CalcuDoku uses addition, subtraction, multiplication and division in ways which are deeper and more gratifying than anyone can imagine.”

Each puzzle consists of a grid containing blocks surrounded by bold lines. The object is to fill all empty squares so that the numbers 1 to N (where N is the number of rows or columns in the grid) appear exactly once in each row and column and the numbers in each block produce the result of the math operation shown in the top-left corner of the block. In **CalcuDoku** a number may be used more than once in the same block. To see how it works, try out the interactive tutorial here…or add the widget to your blog where you can play an Calcuduko which gets updated regularly.

Hi,

Find more Calcudoku puzzles here: http://www.calcudoku.org

And maybe you can correct the “Calcudoko” in the title, and the “Calcuduko” in the text?
