In no row, and in no inclined column (inclined on left or right), numbers are repeated. Fill every box with digits 1 to 9. Leave EMPTY the three border cells in the middle.
This puzzle has some colored marks. All marks are given; they give you information about the two adjacent numbers (every cell has six neighbours!). Some marks may be present on lines connecting two cells!
When the sum or difference is exactly 5, the mark is orange.
When the sum is less than 5, the mark is green.
When the difference is more than 5, the mark is red.
When there is an arrow on a row, or on an inclined column (inclined on left or right), the number pointed by the arrow is not present.
As a consequence, the fives can be placed only ... where? And can you complete the whole puzzle?
Solution code: The numbers you must put on inclined columns with arrows, numbers top to bottom, i.c. "9" then i.c. "8".
