Brain Test: Tricky Puzzles is a trivia brain teaser game by Unico Studio that challenges players to solve a series of unconventional riddles and logic puzzles. It moves beyond simple quiz formats by frequently breaking common sense, requiring lateral thinking rather than straightforward knowledge to progress.
This game serves up a huge collection of mind‑blowing teasers where the most obvious answer is rarely the correct one. Designed for quick, engaging play sessions, it works entirely offline, making it a reliable companion for commutes or moments when a short mental distraction is needed. It is explicitly aimed at anyone looking for a fun, brain‑pushing experience, whether playing alone or passing the device among friends and family.
From a privacy standpoint, Brain Test keeps technical requirements minimal. According to its listed permissions, it only requests access to Wi‑Fi connection information, a relatively low‑impact permission that typically helps with ad targeting and content delivery rather than collecting personal identifiers. There is no request to read contacts, access precise location, or scan device storage, which makes it a lighter load on your data privacy than many free games.

Latest changes
The latest update includes bug fixes for some levels. New levels are expected in an upcoming update.
This game is for puzzle enthusiasts of any age who enjoy thinking outside the box and are not easily frustrated by intentionally misleading questions. It is particularly well‑suited for anyone seeking an offline, low‑permission brain training app for short breaks, family gatherings, or casual solo play.
If you find yourself stuck, try to completely abandon the question’s literal meaning and look for a visual trick or an interactive element on the screen; shaking your phone, swiping in unexpected directions, or interpreting text as a physical object often reveals the solution. Since the game is offline, you can also use it in airplane mode to eliminate ads that might rely on a network connection.
