Various Hints
Don't rest on you laurels when a chain starts - look to extend it by continuing the block matching.
Use bonus blocks such as Melon Bombs to extend combos, waiting to activate them in the middle of a chain reactions.
While it’s fun simply comboing and boosting your score, keep an eye on your true target - to level up by meeting each level's Piyo quota.
