You’ll be forced to clear the 9 in the middle and activate the blaster on the first try, but if you’re lucky enough to get a board like this on another try, clear the other power-up matches before activating the blaster.
Clear the blue in the middle for the bomb, but then continue normally clearing the highest number of blue per move. If you get a chance for a quick bomb/rocket combo, that will pretty much clear enough to hit your quota.
