You can run active bling while going for your Cherry Bombdigity and Cherries Gone Wild. But becareful and start your first bomb about an hour after you start other bling or it won't count.... Many have made this mistake including me. It took me 9 bombs to do 8 consecutive.
Cherry Bombdigity and Cherries Gone Wild can be run in hours or in years... it is up to you... The key is NOT to run any other bling until you complete it.
Remember you have to pass 4 to get to 8 so you can plan and do them both at the same time which requires 8 bombs.... Only run bombs until you do 8 of them. I know someone who has been working on it for months. Each bomb counts towards the total and he is committed not to run anything else until he completes it.
If you chose to run it in a day... You can take a break for an hour or 10 at any time during the day.... as long as you don't start any other active bling aka powerups....
It is also a good time to go for your Cherry inferno. 115 albums is harder than you think but possible. With your first 2 bombs bomb those you want to bomb doing the inferno.... then go back and book mark the album you wanna bomb... get a good timer.... and start the 3rd bomb... using bookmarked albums do bomb run... Time 30 seconds then click bomb.... move on to next.... Albums must be prebombed to work and if you book mark album it keeps fu from slowing you down.
By doing Cherries Bomdigity and Cherries gone wild together you save the cost of 4 bombs... 140 credits... and if you get any of the bombing achievements you save even more. Cherry Melt is 60 albums, Cherry Ignitor is 90 and Cherry Inferno is 115.
Remember to have fun.
If you have any questions ask.
Good Luck
