Monsters in many colors, all of them cute. In Monster Match Mania you match three monsters of the same color to eliminate them. The graphics are bright and the levels are short, so it fits a coffee break.
What keeps it interesting is variety. Levels are themed, and each theme comes with its own obstacles, so a trick that worked in one world needs adjusting in the next. Power-ups and boosters can be combined for bigger scores. Plan two monsters ahead, make chain matches for the bonus points and save the boosters for the levels that really need them. Another one to try: Match 3 Jewels.
