How to Play Smyle | Rules, Setup & Gameplay Tutorial

About Smyle, from BoardGameGeek:

Smyle is a competitive memory card game for 2-5 players and ages 8+. Each player begins the game with 3 facedown Teeth cards worth either positive or negative points, and draws a hand of 4 Tooth Fairy cards. Players will know what Teeth cards they have at the start of the game but can't check their row of cards, called their Smyle, unless an effect allows. At the start of each Round, every player simultaneously plays 1 Tooth Fairy card, which determines whether they are going to Steal a Tooth from an opponent, Give 1 of their Teeth to an opponent, Swap a Tooth with one of their opponent's Teeth, or Draw a brand-new Tooth card from the Spare Tooth Deck or activate a Gadget with a unique effect. But players aren't left completely in the dark. At the end of each Round, players must flip 1 of their Teeth cards face up for all to see. Choose wisely as some Teeth generate negative points, called Tooth Decay, when Revealed! Will you take the time to care for and clean your Teeth, or pass off your Decay-ridden Teeth to someone else? After 6 Rounds, the player with the best-looking Smyle wins the game! -description from the publisher
