You have 3 color bombs frozen down below, so you really only need to make 2 and set the others off. To get to them though you need to make your way through the 4 hit blocks and the spinners. Try to make vertical matches in the 4th and 6th columns to maximize the block destruction. With the missing spots in the board it is a bit harder to make the color bombs on this level though.
