Level 146 has 33 bubbles to clear, all of which are covered by bricks, or about 0.75 moves per thing you have to clear. Remember that torpedoes won’t clear bubbles that blocks aren’t behind, so it’s better to work top down. Be sure that if you clear blocks to make torpedoes that you tap on a block in a row/column with stuff that needs to be cleared. Regardless, you may need a bit of luck to get better than 1 star.
