1 Bomb Bubbles
1 Lock Bubble(1 chain)
Start level 128 by popping those bubbles you easily can reach, don’t use the RB bubbles yet. When having cleared the right side, bank shots via the wall to reach the lock. If possible, drop the black bubble row before unlocking. Dropping the black bubble row will save you a bit trouble with the infection coming down at the left side.
Don’t let the infection attach the Bomb, because that will make it harder to drop the middle back bubble row. If the virus attach itself, the game can still be played for a good score, you just have to think it through a bit more. ;-)
You can let the virus spread one row lower then the middle black bubble row and still be able to reach sight for the ceiling.
