Mysterious Elevator is a free online math puzzle game where you must solve equation-based logic challenges across 100 floors of a haunted skyscraper. Your only tool is a creaky old elevator, and your only way out is your brain. Swap number blocks and sign blocks to assemble correct equations before the elevator crashes and sends you back to square one.

Each floor throws a different type of challenge at you, starting with basic arithmetic and escalating into sneaky logic traps that will catch you off guard if you rush. The sarcastic Keeper of Numbers taunts you throughout, which actually adds a layer of tension that keeps you sharp. There are no random luck mechanics here — every mistake is a thinking error, and every correct solution feels genuinely satisfying. The atmospheric design and old-elevator setting give the game a mystery-puzzle vibe that separates it from standard math drill games.

This game is a great fit for players who enjoy brain teasers, escape room puzzles, and educational logic games that actually challenge adults, not just kids. If you search for math puzzle games online, number logic escape games, or free brain training games with no download, Mysterious Elevator delivers on all fronts. It works directly in your browser, completely free, making it easy to pick up for a quick session or grind through multiple floors in one sitting.
