Steps to working out the 4 by 4.

1. Figure out the cage of box 1 first
2, Then move to the 7+ cgae, but only 3 and 4 can fit in the 7+ cage. But 4, is already placed in the bottom cage.
3. So then the last box in the 4th column must be 1.
4. We placed possible numbers in the remaining boxes and used trial and error to solve the remaining boxes.
