The lollipop hammer is a very useful booster in Candy Crush Saga. When you first start playing the game you will receive a few free lollipop hammers. Many people make the mistake of using these boosters right off the bat. This is not a good strategy. You should save these as long as you can because they are very valuable. The lollipop hammer will simply crush any candy on the board, you wish it to crush. Just select the lollipop hammer and click anywhere on the board and it will crush it. This can be very useful in ingredient levels where you are one candy away from winning and you just need to crush 1 candy. Just remember to not use the free ones you receive until at least level 70, which is one of the hardest levels in the game. Use them wisely!
