Shataka - a JavaScript number game

 Now that I have reached a certain age, I can only recycle old ideas. 

I modified the hundred app into a web page. 

It is a simple JavaScript app. You can get its source code here

The aim is to get a sum of 100 for each row and each column of the grid. The grid has 3 rows and 3 columns. 6 of the 9 numbers are already given. 

Let us look at an example. 

Now last row in this example is already filled. And it adds to 100. Let us look at first row. It has 7 and 20. Which means we need 100-20-7 = 73 to make 100. So fill 73 in first cell. Similarly fill 75 in second row first cell. 

This is the solved puzzle 

You can view the game in my github page.
