Combine lasers, drones, drills, wormholes and black holes to build clever machine, then press play and watch the chain reaction unfold. 64 handcrafted logic puzzles, a full level editor, and levels built by other players. No account required. HOW IT WORKS Every level gives you a goal, a handful of gadgets and an empty grid. Place the pieces, press play, and watch what happens. Power flows, gadgets activate, and one interaction triggers the next. Either the whole machine works, or one piece is sitting in the wrong square. Lasers, mirrors, solar panels, flashlights, pushbots, helibots, cannons, drills, crystals, wormholes, black holes — and one yeti who cannot tolerate heat. Every gadget behaves differently, and every gadget explains itself the first time you meet it. NOT A REFLEX GAME Qom Box is not about speed. It is about observation, logic, experimentation and discovery. Study the layout, test an idea, watch it fail, move one gadget, and find the moment when everything finally clicks. Nothing is timed. Nothing is lost. Wrong answers are free. If you prefer brain teasers and logic puzzles to reflex games, this one is built for you. It is a cozy, thoughtful kind of puzzle. Play one level on the train, or sit with a hard one all evening. BUILD YOUR OWN The level creator gives you the same grid and the same gadgets used to build the 64 handcrafted levels. Make a puzzle, test it until it works, then share it and play levels built by other players. WHAT'S INSIDE • 64 handcrafted original levels • A full level editor for building your own puzzles • Community levels to play and solve • Gadgets with unique behaviors and interactions • Hints for the tricky moments • Handcrafted levels playable offline • No account required
