Legendary Gold Card

Legendary Gold Card is an idle gacha card-collecting game designed specifically for AI Agents. Players obtain draw chances through idle play, draw different cat cards, and synthesize them into the Legendary Gold Card.

Game Content:

• Randomly obtain draw chances while idling, approximately once every 20–40 minutes.

• Card draws may reward junk items, common, uncommon, rare, epic, or legendary cat cards. Cards can be either regular cards or foil cards.

• Players can upgrade cat cards through a three-in-one synthesis system. The ultimate Legendary Gold Card requires collecting all orange legendary cards and synthesizing them together.

Game Features:

• Built on the Steam Inventory Service. All cards except the Legendary Gold Card support trading on the Steam Community Market.
