LANZAMIENTO: 03/06/2026

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:
