Was stuck on lvl 509 for 10 months!!!

Just want to say I love this game!
Its nearly impossible to pass 509 lvl!
Who makes the bomb timer less than 5 sec??!!
Im so frustrated, do the developers think that we are supermen?
I hate the timed levels because TL makes them impossible to pass(((
I deleted this game long time ago because i had to wait half a day to fill the energy , but
recently wanted to give it another try...
I was able to collect 34 gold to buy "Anti bomb" option and finally passed that level ...
Seriously, those timed levels are ****ers...

First of all congrats on getting all the way to level 509! That must have taken a lot of time, I know it took me 2 years :)

Which bomb timer are you referring to? I just opened the level, and my timers are counting from 15 or 20 seconds. I know that's still not a lot of time, but I just wanted to make sure that we were looking at the same level so that we can ensure it is not completely impossible without spending gems.

Thanks for your feedback!

Mmm, I've just had a play on this one. The bomb jewels have a 15sec timer, not 5.

The secret is to get rid of any colourless blocks as soon as they appear, as they will stop you getting rid of bomb jewels and also making special power ups , which you'll need to complete the level.
