Who is? Brain Teaser & Riddles

What the game is

Who is? Brain Teaser & Riddles is a trivia puzzle game from Unico Studio built around short mystery scenes. Instead of testing general knowledge, it asks you to work out who is lying, who is responsible, or which person fits the clues. It suits players who prefer observation and deduction over timed quizzes and memorisation.

How the puzzles work

Each challenge presents a situation that needs more than a quick guess. You may need to compare the people in a scene, notice an unusual detail, or find an object that changes the answer. The game uses lateral-thinking questions and hidden clues, so the most obvious response is not always the correct one.

• Identify suspects, liars, criminals, or other characters from visual evidence.
• Inspect scenes for details that support a solution.
• Use reasoning rather than relying on broad trivia knowledge.
• Work through puzzles at your own pace instead of competing in a rapid-fire quiz.

Who may enjoy it

This is a good fit for casual players who want compact brain teasers with a story-like setup. It can also appeal to families and younger players who enjoy cartoon-style mysteries, though some answers require flexible thinking and careful reading of the scene. Players looking for a traditional quiz covering history, sport, or geography may find its format less familiar.

Popularity and standing

The app carries a 4.67 rating from more than 1.79 million reviews and has reached 50,000,000+ installs. Those figures place it among the more established entries in the Trivia category. Its focus is clear: a large collection of visual riddles where paying attention to small details matters as much as choosing the right answer.
