Smile Style is a semi-dynamic paper doll makeover game that features six Disney-esque princesses who want to win an online challenge in which each girl's style must attempt to match the emotions or attitudes of onscreen emojis (i.e., in love, happy devil, frowning while angry, cool dude, joyful angel and crying while sad). The player's goal is to help each princess look her best with makeup and accessories.
The game doesn't feature category or item selection like many makeover games. Instead, the player waits for the game to select a tool. They then use their controls to prompt the game to automatically apply the makeup or accessory.
The options vary by princess and look but typically include foundation and blush with or without stencil art, eyeshadow, eyebrow color, black or white mascara, contact lenses, lipstick and a hairpiece. The game applies additional costume pieces, such as wings for the devil and angel looks.
Smile Style also allows the player to select a matching background. They can then use a camera button to download a screenshot.
