Brain Test 2: Tricky Stories

The "Brain Test 2" franchise, developed by Unico Studio, represents a pivotal evolution in the mobile puzzle genre. Spanning across multiple versions —Tricky Puzzles, Tricky Friends, and All-Star—this series has redefined lateral thinking games by moving away from traditional math or word puzzles toward interactive, "logic-breaker" scenarios. The foundational design of the series is built on the "Impossible Quiz" concept, where the solution to a level often requires the player to ignore common sense and interact with the game's UI in non-literal ways, such as shaking the device or moving elements off-screen. This approach has proven immensely successful, with combined downloads across the franchise exceeding 100 million.

The sequel introduced a "narrative-first" approach, where puzzles are organized into chapters following specific, colorful characters like "Tom the Cat," "Emily’s Farm," or "Monster Hunter Joe". This evolution significantly improved user retention by providing context for the puzzles and allowing for character-driven dialogue and continuing stories.
