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.
Make the power and finish. You can make power up combos, but you you’re pretty limited in scoring opportunities this early.
Clear the yellow pair on each side, then get all of you red quota in one move.
Make torpedoes and TNT (I find a torpedo-TNT combo the most effective). If you get a torpedo facing the wrong way, try to pair it to ensure clearing out piggy banks.
Focus on clearing the corners and middle with torpedoes and TNT. Beyond that, chain reactions with torpedoes help–but be sure to avoid making a cube power up before you’ve cleared much of the board. You’ll end up having to waste it and the moves it took to create and clear.
You have 48 clears to make in 30 moves. Usually, with bubbles, that isn’t too bad, but on this level, the shape of the board makes the singles on the edge harder to clear. Don’t worry too much about the eggs. Make sure you make each move clear as many bubbles as possible. Even with that you’ll still need some luck to get through.
You’re likely going to have to make a couple of moves to position like-colored blocks next to bricks to clear them. Once you clear a few blocks (hopefully up higher), you should be able to get some power-ups. Clear torpedo-making block combos above the toys on the chance that you’ll get a vertical one that will clear the toy. Otherwise, torpedo-torpedo or torpedo-TNT combos will help clear a pathway for the toys.
Don’t fall asleep on this one, you need to clear the sides. However, many starting layouts will already have a torpedo or TNT setup for you, and you can usually clear those into a two cube combo.
You have more than two times as many clears to do here as you have moves. Fortunately, one of the first moves here touches 8 eggs. Just make sure you maximize the number of eggs touching your moves. It will still help to get at least one TNT/torpedo combo.
This one is a little tougher than the previous level. You have 40 clears to make in 30 moves, but you also don’t get additional eggs to make matches on. Best to go for matches next to three eggs at a time. The last few clears will likely burn a few moves.
