Wow, thanks for the warning--great advice! I've always known that the color-changing white blocks become the color of any jewels cleared next to them. But the fact that they also become super dirt (if super dirt is cleared next to them) is not good news! Yuck!
Do blasters work over bombs cuz they also take out the ice/white blocks? What if, say, you had a row of super dirt with white blocks underneath. If you cleared the super dirt row with a regular horizontal blaster, wouldn't the white blocks then change to super dirt? Sorry, I find this fascinating, lol! I guess you could always use a regular jewel match to color-change the ice first, then you wouldn't have the super dirt problem (but it would waste time/moves, lol.) Thanks, Aileeniweeni!
