The Card Collection is an album of themed card sets, with 9 cards in each set. New sets are added over time, so there's always more to collect. Earn cards by clearing levels, trade duplicates with friends, and complete sets to earn rewards. You can open your album anytime from the collection icon on the main screen — a red dot means you have new cards waiting.

Every card has one of three rarity tiers: Common, Rare, and Legendary. Legendary cards are the rarest — each set contains just one, marked with a special gold frame. Rarer cards appear less often, making them the most valuable to collect and trade.

Cards are earned by winning puzzle levels. Not every win finds a card, but keep playing and your collection will grow. Keep your win streak going — the longer your streak, the better your chances of finding Rare and Legendary cards. When you find a card, it's added to your collection album automatically; you never have to interrupt your play. If you find a card you already own, it becomes a duplicate you can send to friends.

Cards you hold more than one of can be shared with friends:

Only duplicates can be donated or traded — your last copy of a card is always protected. You can send up to 5 cards and receive up to 5 cards per day.

Missing a specific card? Tap Request on its empty slot in your album to send a card-specific link to a friend or group on LINE. A friend who has a spare copy can send it to you directly. You can also share cards you've found to show them off.

Card links work for everyone — even friends who don't play yet. When a new player taps your card link, they start the game holding two copies of that card: one saved to their album and a spare they can choose to send back to you. You'll also be added as friends automatically. Note: Legendary cards can't be granted through links — new players receive a Common or Rare card instead.

Collect all 9 cards in a set to earn set rewards. With new sets added over time, there's always a new set to complete.
