We have three blocks. Lets call them A, B and C. Block A contains one medium black square. Then, there is block B. It has one medium blue square. Finally, we have block C. It is below block A and above block B. It has a medium yellow square and one medium blue square. There is also one medium black square touching the bottom edge of this block. The medium yellow square is below the medium blue square. The medium black square is below the medium yellow square and the medium blue square.
