level 77

I don't have much advice on 77. I got very lucky and finished in about 10 min.
I just started by randomly clicking on tiles ( mainly on top and upper sides ) just to see where they would go. After a few tries, I knocked out several tiles ( yes the portals were used ) and noted that the sides and upper parts could be used to get around the board Near the end I had the blue 5 & 6 on right at bottom right but needed to swap them. I did this by using lower jumper to stack one on top of each other and now they were ready to go all the way over
to finish. Hope this helps some.
Level 78 has several enclosed areas. Looks like it's going to be very frustrating.OH HOW FUN!!!

I started this level using the 2 tiles in the bottom right, after that everything seemed to open up.

I started with the N and solved it pretty quickly.
