This level is difficult because all of the spinners are on the left. With only 30 moves to play with, you have to employ the double color bomb to make it through this level. So what you will do is unlock either or both of the top color bombs and work one or the other down to the bottom of the board. Once you have 2 color bombs together mix them and that will remove all of the spinners for you! Now you still have to deal with the double jelly over there, but you have pieces and striped candies to help you clear through this. Use the vertical striped candies to zip through this. The hardest part is getting the color bombs down without setting them off. If you need to get the color bombs down by one piece, use another color bomb to remove the color in the way to be able to mix them.
Patricia Frederick’s Tips for Candy Crush Level 210
Try to release the color bombs on ONE side of the board only. You want the top one to drop down to the bottom one to match together. When they do, they will hit all the licorice whirls out of the way and then on the right hand side board, they will release the other 2 color bombs which you should match together. This will hit every jelly on the left side once and simple matches can clear those weakened jellies quickly. (If you accidentally exploded a color bomb and don’t have 2 for the last move I mentioned, don’t worry you can still beat the level. It just takes combos or at least striped candies to clear the double jellies.)
