I've been stuck on this Detective difficulty puzzle for a while now and cannot figure out the trick of it... I can clear the middle portion just fine, but the sides? I mean, since you have to make a vertical match-4 to create a horizontal special block (which falls to the bottom of the opening created), how do you take out the upper side columns?! Is the only way with rainbow blocks? Because those are *tough* to make in only a 5x7 maneuverable grid!
