Stealthy Heist is a free online stealth-action game where you step into the shoes of a master thief, planning and executing precision heists across increasingly guarded locations. Your job is simple on paper: get in, grab the loot, and get out without triggering a single alarm or letting a guard spot you. The catch? It's anything but simple.

Each level plays out like a puzzle with moving parts. Guards follow patrol routes you need to memorize, security cameras sweep at timed intervals, and safes require cracking under pressure. You'll disable alarm systems, use gadgets to slip past laser grids, and make split-second decisions when plans go sideways. Upgrading your gear and unlocking new thief skills keeps progression feeling rewarding, and the difficulty ramps up steadily without feeling cheap. Smooth controls mean your failures are on you, not the game.

Fans of stealth puzzle games, casual heist challenges, and hypercasual arcade action will all find something to enjoy here. If you like games that reward patience and sharp timing over button mashing, Stealthy Heist hits that spot. It's a solid pick for anyone searching for free thief games online, stealth arcade games no download, or casual puzzle heist games to play in the browser. Every run teaches you something new, and nailing a clean heist with zero detections never gets old.
