This post describes how Google built the interactive Save the Date puzzle experience for Google I/O 2026 using Gemini AI models throughout development.
- •The team used Google AI Studio for early prototyping and Google Antigravity for agentic development as game complexity grew
- •Gemini generated levels dynamically for Nonogram (boards 2-3), Stretchy Cat (Hamiltonian path-based solvable levels), and Word Wheel (100 levels)
- •Hole in One integrates Gemini as an AI caddy that provides contextual tips and commentary tailored to each player's gameplay
- •Supersonic Bot uses Gemini to process microphone input, where voice volume controls the Android Bot character
- •Dino Pal, an unlockable virtual pet, uses Gemini to assign personality traits that adapt to the player's play style
