All the jelly is again double jelly here and is in the asterisk formation. 50 moves seems like a lot, but the 4 corner pieces are the hardest to remove. Try to work out and remove the blocks to get to these pieces and zip a striped candy through to clean house and help you zip through the most candy at once. Just keep an eye on any chance to remove the corner pieces before you make a move.

Clearing these jellies is pretty straightforward except for the 2 in the bottom corners. There are a variety of ways to nab those: color bomb matched to their color; horizontally striped candy matches, striped/wrapped combo (one made in the bottom rows of the center portion of the board works really well.)
