Cookie Stack with Ottie

A cozy cookie-merging puzzle against Ottie, right inside ChatGPT. Swipe, use arrow keys, or tap a direction to combine matching cookies. Both trays receive the same cookie drops. The biggest stack wins; merge score breaks a tie. Requires an MCP Apps UI. No Ottie’s World account is required. Temporary game instances expire 20 minutes after creation and reset on server restart. Progress does not transfer to Ottie’s World.
