Level 3413

Complete as many special events as you can, such as magic dash, feeding rami/didi and anything else that will give you boosters at the beginning of the level. Get setup so you start with at least 2 color bombs. Wrapped and striped will help too. It takes some luck but before too many tries you should have 2 color bombs next to each other. When that happens, combine them and it will clear all the blockers. After that it's not too difficult. Just did it in 6 moves that way.

This is an answer to Steve: goal is to succeed without any booster ! This is not really the case in your answer, I guest that your are kidding!

Keep on trying and you will surely clear it soon!!
