Ethane Gas

Ethane Gas is a fast, satisfying bond-building flow puzzle set inside a tiny chemical reactor. Ethane molecules stream out of the cracker on the left side of the grid. Every tile holds a covalent bond segment that you rotate with a single tap. Build one sealed chain of bonds so the gas can flow safely into the collector on the right, and do it before the stream hits a closed end. HOW IT PLAYS - Tap any tile to rotate its bond 90 degrees and reroute the flow. - Gas enters a tile only through an open bond end, so every rotation matters. - If the stream hits a wall or escapes the grid, you lose one of three pressure cells. - Each successful vent raises the level and the gas flows faster and faster. - Earn coins on every run and unlock new gas trail styles in the shop. FEATURES - One-touch rotation controls that anyone can learn in seconds. - Real-time flow physics with a glowing ethane molecule riding the chain. - Endless level scaling that keeps the pressure rising. - Four collectible gas trails: Cyan Spark, Lime Catalyst, Amber Flame, Violet Plasma. - Synthesized retro sound effects, vibration feedback and persistent best score. - Fully offline, no ads interrupting your run, no account needed. Plan your route during the countdown, keep the chain sealed, and become the master of the molecule stream.
