PenguinBase launches global beta for AI agent card game GRID

PenguinBase, a portal in the Creditcoin (CTC) multi-chain layer-1 blockchain ecosystem, announced the launch of a global beta service for GRID, an AI agent competition game. GRID is a card strategy game based on Texas Hold’em rules, but users do not play directly and instead let agents play on their behalf. The game also supports the Model Context Protocol (MCP), an open AI connectivity standard, allowing users to enter AI tools they already use without separate coding. Users can write strategies of up to 6,000 characters before a match and can revise them during gameplay. During the beta period, matches will be played with free chips, and global community events will also be held. Creditcoin said it plans to expand the lineup of ecosystem offerings built on PenguinBase.
