Sheets and ladders. Draw bands between the sheets then wiggle to pull them together. Shake may help. Try deleting the bands then wiggle and shake again to gain more points.

About three bands between each pair of sheets should be enough.

You'll notice there are blue dots and red dots along the edges of the sheets. The blue dots can form hydrogen bonds with the red dots. Also, the red dots are on "hills" and the blue dots are in "valleys". The hills and valleys should fit together.

After wiggle, try shake for a few extra points. Delete the bands, then wiggle and shake again for even more points.

Technical stuff: notice that the sheets in this puzzle aren't flat like the ones in the first couple of puzzles. Welcome to real life. Nothing is very flat or straight in the protein world.
