I need help with level
All our levels can be completed without purchasing lives, coins or boosters. Our developers only release levels after they personally ensure that levels are beatable without the use of purchases. Boosters and coins can give you the extra edge you need to finish a level, but they are entirely optional and are not needed in order to pass any of our levels.
Try to make special matches and combinations ( for example 4-5 in a row) to clear hard levels. You can find more about special combinations here.
