A striped candy and colour bomb combo should take care of the bombs at the bottom, then you need to focus on crushing the meringues and clearing up the jelly.
A little on the tricky side, but there’ll be plenty of opportunities to make colour bombs and special candy along the way. Use them wisely to finish up this level.
The jelly on this level is at the bottom of the board and some is covered in double-layered meringue and 12 squares are covered with 30 move bombs. You have 55 moves in level 434, which sounds a lot.
You want to start by destroying the bombs. Vertical striped candies are great for this and combining striped and wrapped candies can do a lot of good if used on the right or left hand side of the board. Removing the blockers will help to provide the space needed to make these combinations, but it will also eventually unblock the chocolate spawner at the bottom of the board. These blockers need to be removed to destroy the jelly underneath though. As they are removed it could be possible to use horizontal striped candies or striped and wrapped to clear more of the bombs. A color bomb and striped combination is useful at any point in the game to clear blockers, chocolate or jelly. Once the bombs are removed, you will need to use the same techniques to remove the jelly that was under them.
Level 434 is difficult with quite an element of luck. You will need to keep making as many special candies as you can but make sure that you use them effectively. Starting with a color bomb or striped and wrapped candy could be very useful here. A bomb cooler may help as well as might the sweet tooth booster. However, it is probably just a case of playing level 434 enough times that you get lucky with the candies and manage to clear the bombs quickly enough.
