This level is currently nearly impossible to beat without boosters (or even with boosters). This is probably caused by a design error or a glitch, or an objective which requires extreme insane luck to fulfill. This level is currently one of the hardest, if not the hardest level in the game. Please remove this template when the level is nerfed.
When there are no (or just one) vertical striped candies in the middle, make striped candy+striped candy combos on the left hand side of the board such that they wipe one of the horizontal striped candies in the middle row, hoping they will be replaced by a vertical striped candy. You will need those to clear choco blocks.
After all the striped candy orders have been fulfilled, avoid making horizontal matches on the left hand side of the board, as they will likely create a full row of chocolate, requiring striped candies or boosters to break them up again.
Hope for a lucky board with cascades. (Boosters do not seem to be very effective, unless you are willing to use an insane amount of them.)
