Who is? Brain Teaser & Riddles

The best thing about Who is? is that it does not ask you to be clever at reading — it asks you to rummage. The answer is buried in the picture rather than in the wording, and that mechanic, more than the jokes or the art, is what we think carries a 4.7 average across 1,610,538 ratings.

What the rummaging actually is

Our source material’s description records the format as stylized cartoon scenario questions — it offers “Who is the killer?”, “Who is lying?” and “Who is the imposter?” as the kinds of prompts involved — where the solution is rarely obvious at first glance. Getting to it means working the scene: dragging items to reveal what sits underneath, checking character pockets, uncovering background elements that trigger flashbacks and expose a contradiction.

Our own material calls this a “major structural shift” in the genre; that is positioning language, not a measurement. Strip it off and something concrete survives: the puzzle is not the wording of the question, it is the search. Our own editorial database lists that as the leading strength, crediting the interactive visual-clue system with turning standard text riddles into mini-detective scenarios, and one reviewer on record says dragging objects to find hidden evidence is a great way to engage your brain. Our source material also records the game as building on Unico Studio’s “Brain Test” franchise; that recorded lineage is the whole of what we hold on the connection, and we have not compared the two.

The 30-second problem

This is the loudest single thing in our records, so we will be plain about it. Levels are short — our source material records them as typically taking less than 30 seconds to solve. Against that, it records unskippable 30-second ad breaks between rounds, and records that this can make the ad-to-gameplay ratio feel highly unbalanced. That characterisation is our own material’s assessment and we report it as that. Our own cons list carries the same theme under “Repetitive Ad-Block Interruptions”: a high frequency of unskippable ads after short levels, significantly disrupting the flow of gameplay. So does one of the four user reviews on record — clever puzzles, that reviewer says, but an unskippable video ad after every single short level is frustrating.

Three parts of our record converge, and we will not go past them: we have no measurement of real ad frequency, and what is recorded is a complaint about interruption and nothing else.

What removing the ads covers, exactly

Our database’s FAQ records two routes to ad-free play: a one-time in-app purchase that removes ads, and playing the game ad-free as part of a Google Play Pass subscription. Worth flagging rather than smoothing over — our own descriptive write-up mentions only Play Pass while the FAQ records both, so we report both.

Two limits. No price is on record, so we quote none; check the live Play listing before spending. And the recorded scope is ad removal: our records do not describe either route as unlocking levels, hints or any other content.

Where the interaction gets in the way

The second recurring complaint is mechanical rather than commercial. Our cons list records finicky drag-and-drop sensitivity: interacting with smaller items can occasionally feel unresponsive, sometimes requiring multiple precise taps before a clue registers. One recorded reviewer describes it directly — knowing the correct solution, but tapping several times before the game registered they were holding the clue, with some items too small on a phone screen.

That matters here because of what the game is. When the payoff is the moment of realisation, an input that fails to register leaves you unsure whether you were wrong or just imprecise. We hold no data on how widespread it is — one recorded review and one cons entry is the whole of our record.

”Every level is unique” — what that does and doesn’t tell you

Our database’s FAQ records no repeating levels: per that entry, Unico Studio ensures every level is unique, with a distinct scenario, its own custom-drawn characters and its own puzzle logic. Our own pros list describes dozens of unique, story-driven logic challenges and credits that with keeping the puzzles from feeling repetitive.

“Dozens” is the only volume language on record; we hold no exact level count and cannot say how long the content lasts. And uniqueness carries a cost our own cons list names: because each scenario resolves the instant the clue is found, there is no extended detective mode and no deeper multi-stage investigation. What you get is a run of self-contained one-shot puzzles — a coherent trade for something built to fill five minutes, but if the detective framing had you expecting a case to work through, it does not go there.

Offline play, and the shape of a session

Our database’s FAQ records the entire riddle database stored locally and the game fully playable without an internet connection; our pros list credits that as a good fit for commutes. With sub-30-second levels, the intended use is easy to picture: the queue, the platform, the five minutes before something starts.

The presentation suits the same context. Our source material records funny cartoon animations that respond dynamically to touch, comical sound effects, and a clean interface that supports comfortable one-handed play, and one reviewer on record credits the hand-drawn cartoon art and humorous character reactions for the entertainment. Our FAQ and our pros list both record an intuitive hint and clue-detection system that highlights evidence when you are stuck.

The “brain teaser” in the name

Worth keeping separate from everything above. The title carries “Brain Teaser”; one reviewer on record calls the game a great option for a lighthearted brain workout, and another says dragging objects to find hidden evidence is a great way to engage your brain. Those are the product’s own name and two people describing their own experience.

We have verified none of it: we hold no research, no study and no measurement on record about what this or any comparable puzzle game does cognitively. That is not an argument in either direction — we are not suggesting the language is wrong, only that our review cannot support it. What our record supports is narrower: short observational logic puzzles that are enjoyable to pick apart.

The recorded age rating

Our database’s FAQ records the game as rated Everyone 10+ on the Google Play Store, attributing that to mild cartoon violence and occasional crime-scene investigations. That is the whole of what our records hold on content, and we add nothing to it.

A recorded complaint about the marketing

Separately, our own cons list records a complaint aimed at the app’s marketing rather than at the app: some marketing ads are described as featuring clickbait themes and gender stereotypes that do not represent the actual puzzle content. That is the recorded scope in full. We have not seen those ads, and we pass the entry on as recorded feedback rather than as a finding of our own.

Scale, recency and the category

4.7 across 1,610,538 ratings on 50M+ downloads is a large, consistent signal, and not one a desk review argues away. Our record shows the Play listing updated December 29 2025, a little over seven months before we wrote this, which is the most recent listing update we hold.

We ran no head-to-head test and hold no records on other puzzle games, so we draw no comparison — only the observation that here the answer lives in the scene rather than in the sentence.

Who it’s not for

Look elsewhere if you want uninterrupted play on the free tier: our records describe short levels punctuated by unskippable 30-second ad breaks, and if that pattern grates you will not last. Likewise if you wanted a multi-stage investigation, since our cons list records scenarios ending the moment the clue is found. Anyone who finds small drag targets frustrating should weigh the recorded sensitivity complaints, and anyone after a verified cognitive product should note that the brain-teaser language is the app’s name and a reviewer’s phrasing, not something we checked.

Our take

The core idea is strong and it is the reason to install: turning a riddle into a scene you search rewards curiosity rather than recall, and our records show players responding to exactly that — the clue hunt, the cartoon reactions, the fact that it works with no signal. The counterweight is pacing. On our record a level takes less than 30 seconds and the breaks between rounds are unskippable 30-second ads, which our own material records as making the ratio feel highly unbalanced and which one recorded reviewer calls frustrating; a one-time in-app purchase and Google Play Pass are the recorded routes out, though no price is on record and the recorded scope is ad removal. Add the drag sensitivity on small items and the absence of a longer-form mode, and this is still a game we would recommend to anyone who plays in five-minute pockets — with the caveat that on the free tier the ad breaks shape a session as much as the puzzles do.
