Season Match (1) , Level 4-15

I am stuck! The board for Level 4-15 needs hundreds of jewels picked (600+) and all tiles cleared to be complete. I don't have time to do both. All of the tools (wand, torch, shamrock) are unavailable. Is there a bomb or other device that will clear the board.
Thank you.

I am trying to find out myself. I would greatly appreciate any help!

I too have cleared all the tiles & used all bombs etc. available at the time. There is no time to get the required number of gems. I'm so stuck. Is there anyone out there who can help???? I found the more big matches you make, the more bombs & line clearing gems you get - if that helps anyone but still not enough to get all the gems in time. Please, any assistance would be great! Thanks.
