You have to get first the yellow block out of the house. Since it is linked to the green, just move this green until both are gathered. Indeed, you will also have to use the whites wisely. At the end, just move the remaining blues.
I agree El. It is very well designed and thought. If I didn't know better I'd say this comes from a very experienced BB player. 26-30 moves ahead thinking is not very simple to design. Very Good Job Aowyn!!
