What is Master Thief?

Master Thief is a hyper-casual stealth game by Ketchapp that focuses on quick, accessible heist-themed gameplay. It is designed for casual gamers who enjoy short, humorous, and action-oriented sessions. While the game enjoys high engagement, it faces significant pressure from a saturated market and negative user sentiment regarding ad frequency. Its primary differentiator is the high-stakes helicopter escape mechanic, which adds a unique flair to the standard stealth-infiltration loop.
