All the outside squares are Jelly coated including the blockers. It’s very hard to get end matches so take the 3 matches when you can clear out all 3 pieces that cover Jelly. Try to put together some striped candies to help you out. The pieces at the bottom are the hardest to remove.

Normally jelly levels are better worked from the bottom to take advantage of cascading candies, but with the odd-shaped board, work any top matches first. A striped/wrapped combo can help clear the jellies.
