In the following grid, the numbers from 1 to 6 occur only once per row, per column, or per colored rectangle. Given the relations between numbers and a single number to get you started, can you complete the grid?

Hints/Tips All worked out! | Comment 5 of 12 |
I played "Find the Ones" and:
  • there's one in the first row, 4th column
  • hence there's one in the 5th row, 6th column (the other possibility in that rectangle would be the 6th row, 4th column, but that isn't allowed)
  • hence there's one in the 6th row, 2nd column
  • hence there's one in the 3rd row, 3rd column
  • hence there's one in the 2nd row, 1st column
  • the last one is in the 5th row, 5th column.
Now for the twos:
  • there's one in the 3rd row, 4th column
  • there's one in the 1st row, 5th column
  • hence the one in the 6th column is in the 6th row
  • hence there's one in the 5th row, 1st column
  • hence there's one in the 4th row, 2nd column
  • hence the one in the 3rd column is in the 2nd row
The threes (and let's write a little less):
  • 6th row, 4th column
  • 2nd row, 5th column
  • 1st row, 3rd column
  • 4th row, 1st column
  • 5th row, 2nd column
The fours:
  • 1st row, 2nd column
  • 2nd row, 4th column
  • 6th row, 5th column
  • 5th row, 3rd column
  • 3rd row, 1st column
  • 4th row, 6th column
The fives:
  • 1st row, 6th column
  • 5th row, 4th column
  • 3rd row, 5th column
  • 4th row, 3rd column
  • 6th row, 1st column
  • 2nd row, 2nd column
And the sixes go in the remaining cells! Whew!!
