King deployed an internal AI-powered testing tool called BAIT (Bot for AI Testing) that checks Candy Crush Saga levels for visual bugs, including missing textures, broken text strings, and overlapping graphics, before updates reach players. BAIT traverses all 4,500+ levels automatically, handling repetitive visual checks so human QA staff can focus on more complex judgment tasks.

Details

BAIT was developed by King's QA team to automate the most repetitive parts of visual testing, specifically detecting rendering issues such as missing textures, missing text strings, and graphical elements appearing in the wrong place or overlapping incorrectly. The bot traverses the full catalog of Candy Crush Saga levels systematically, running checks that would be impractical to perform manually at the same frequency and scale. King describes BAIT as supporting testers rather than replacing them, handling what they call "boring, difficult, tedious" tasks so human QA staff can focus on more complex judgment calls.

Other practices by Activision Blizzard

OtherBlizzard Entertainment maintains a centralized team focused specifically on overseeing how AI can and should be used in its game development process. Individual game teams — such as the Overwatch and World of Warcraft teams — retain the right to opt out of using AI-generated content in player-facing parts of their games. This governance structure was confirmed publicly by Blizzard President Johanna Faries in 2025.Customer SvcMicrosoft is rolling out an AI assistant called Gaming Copilot that Xbox and PC players can talk to while playing games. It can answer questions about where to find items, suggest strategies, recommend new games based on play history, and explain game mechanics — acting like a knowledgeable friend who knows your gaming habits. It launched in beta on the Xbox mobile app in May 2025 and is scheduled to reach Xbox consoles in 2026.Creative GenActivision Blizzard filed a patent in 2022 for a system that would use AI to generate a unique musical score for each player in real time, adjusting the soundtrack based on how they play, how skilled they are, and what is happening in the game. No game has been publicly confirmed to use this system as of March 2026.
