This puzzle is similar to but different from number 500.
If you count the matchstick heads in each diagonal, vertical and horizontal row you will get to the numbers as shown above.
Your challenge is to rearrange the matchsticks to have:
- 4 heads in each row
- 4 heads in each column
- 8 heads in each diagonal row.
Your solution must still be a 2X2 matchstick grid.
