Smileyville features three different modes of play. Each mode has its own set of rules, but the basic premise remains the same: you must arrange smileys into pairs so that do not share any common features. To begin with, the features you need to check are their eyes and mouths, but before long you'll have to worry about hairstyles, body colors and eyebrow expressions. Collect coins to purchase vitamins to help you in your task, while watching out for clown smileys and bonus multipliers to boost your score.
