You Blockhead!

Lately I've been playing Block Puzzle quite a bit on my phone. In the game you take several colored pieces and fit them all into the white space in the middle of the screen.

The available pieces are always strewn about randomly at the bottom in each level. Some levels are pretty easy, others not so much.

Today I got to this level, and the available pieces were arranged like this. Hmm... Gosh, I wonder how I'll ever be able to figure out this particular puzzle? I'm well and truly stumped!
