Candy crush saga level 121 is complicated by the solitary bomb that awaits at the start in the middle of the screen......and the timer makes it especially stressful.
So follow these hints for a better chance of beating this pesky level.
How to remove the bomb
Obviously, your first task is to clear the bomb on the middle of the screen. If you can get a stripe then that will help. Otherwise, focus on working around the bottom of the square of frosting around the bomb. Preferably, focus on the same corner. That way, you can force the bomb to drop out, as the matches will remove the frosting and open up gaps to drop the bomb into.
Always remove the bombs
Always take out the bombs as soon as you can. Don't pass up any opportunities to remove them. They're worth a bunch of points too.
Work the bottom
After you have cleared the initial bomb, focus on matches at the bottom of the screen. This will increase the possibility of cascading matches.
Stripe and wrapped combo
It's the best combo for this level. It clears a bunch of points!
