Unfortunately that doesn't work. All I can find is the colourbombs in my supply, but if I click on there, I can only buy bombs and nothing else happens. How do you finds the contest?
You're absolutely right, I am at level 6605 and many level are allmost impossible without boosters. King made very bad choices. If I can't earn extra boosters and build a bot on passed levels, I must spend weeks to pass the nightmare levels and then I say, no thanks. Time to stop playing Candy crush saga.
