DAY 323

Today’s Challenge

This Kakuro puzzle is ideal for anyone who is new to this fantastic little teaser. I guarantee children’s number skills will improve the more of these puzzles they try. The rules are very simple:

  • Just like a crossword, fill in the boxes,
  • Each box must contain a number from 1-9 and each run of boxes must add up to the total shown on the left or above,
  • You cannot use the same digits in each run, so if a total of 4 is to be completed in 2 boxes, they must be made up of either 3+1 or 1+3, not 2+2.

Here is a Kakuro puzzle to try, which is a little harder than previous ones:

Hint: The secret of completing this is to firstly find the only combinations possible of making both 10 and 11 from four different numbers.

The 7puzzle Challenge

The playing board of the 7puzzle game is a 7-by-7 grid containing 49 different numbers, ranging from 2 up to 84.

The 1st & 7th columns of the playing board contain the following fourteen numbers:

5     9     13     21     22     24     27     28     32     50     55     56     60     66

Which two numbers, when 9 is added to each, become square numbers?
