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.

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.
