Cards are categorized into five types: White Card, Golden Card, Black Card, Rainbow card, and Wild Card. Every card (except Wild Card) has 1 to 5 stars displayed, indicating its rarity.

Card Types:

• White Card: The most common card. It can be traded anytime. You can send a maximum of 5 cards to the same friend per day and up to 20 cards to different friends per day. (Card requests in club do not count toward this limit.)
• Golden Card: A rarer card, only allowed to be traded during the Golden Card Exchange event.
• Black Card: One of the limited-time cards; you can trade these limited-time cards with your friends only during the Black Card Exchange event.
• Rainbow Card: One of the limited-time cards, you can earn extra spins when you obtain it for the first time.
• Wild Card: The most valuable card. It can be exchanged for any card in your collection, including Rainbow Card. It expires 24 hours after you earn it, so use it quickly and wisely.
