Skill Description

🃏 Blackjack

Play a classic game of Blackjack (21) against the dealer, right in the chat. A JS skill that uses run_js to run a full blackjack game engine. The LLM acts as the dealer and manages game state across turns.

Skill Type: JS skill

Features:

• Deal — deals two cards each to player and dealer (one face-down)
• Hit — draw another card, with automatic bust detection
• Stand — dealer reveals and draws to 17, then determines winner
• Natural blackjack detection and push handling
• Hidden card encoding so the LLM cannot peek at the dealer's hole card

Example prompts:

• "Play blackjack"
• "Hit"
• "Stand"
• "Deal me in"

How to use

Load this skill in the Google AI Edge Gallery app using the webhost path above, then try prompts like "Play blackjack". The skill uses a hidden card encoding scheme (prefixing with "x") so the on-device LLM cannot "see" the dealer's hole card. Each action returns the full game state as text. The LLM passes card state back on each turn using the exact values from the previous result.
