Detonate groups of 3 or more same color blocks to win the level.
The bigger the group the bigger the bonus you will receive.
Clear a certain amount of lines per level to clear that level.
The more lines you clear the higher your score will be.
The amount more cleared lines you have at the end of the level the bigger your end of level bonus will be.
Make sure that you have left very few lines at the bottom of the field with each level to get a bigger bonus.
The higher your level the more lines you must clear.
As you progress in levels you will start to receive bombs to help you either clear blocks or in some cases colored bombs will clear their same color blocks.
Detonate and clear to win the game.
