Forget mindless clickers and auto-battlers. If you want a mobile or browser experience that actually tests your deduction skills, Who Is? Brain Teaser & Riddles is exactly where you need to be. Developed by Unico Studio—the mastermind team behind the notoriously tricky Brain Test series—this game launched in December 2018 and has been frustrating and rewarding armchair detectives ever since.
Instead of feeding you straightforward trivia, the game drops you into cartoon-styled crime scenes, awkward social situations, and bizarre logic puzzles. You aren't just guessing; you are actively hunting for clues, dragging items, and exposing liars. But while the puzzles are incredibly clever, the game's aggressive monetization and UI quirks can be a massive headache. Here is everything you need to know to outsmart the puzzles and the progression system itself.

The Core Detective Loop: Unmasking Liars and Imposters
At its heart, Who Is? is a visual deduction game disguised as a casual puzzle app. Every level presents a specific scenario—usually a question like "Who is lying?", "Who is the imposter?", or "Who is the real mother?".
You can't just click on a character and hope for the best. The game requires you to physically uncover evidence first. This involves interactive hidden object detection. You might need to drag an x-ray scanner over a suspect's stomach to see who ate the missing cake, pull a wig off a disguised character, or find a hidden weapon tucked behind a bookshelf. Once you uncover the defining clue, the game often triggers a "flashback answer," revealing the context of the crime or situation before letting you make your final accusation.
How to Play Who Is? Brain Teaser & Riddles
The mechanics are heavily tailored for touchscreens and mouse inputs, keeping the barrier to entry extremely low while keeping the skill ceiling surprisingly high for deduction.
Core Controls
Whether you are playing on Windows, Android, iOS, or via a desktop browser, the inputs are entirely point-and-click (or tap-and-drag):
- Click or Tap: Select: Used to highlight potential clues or make your final choice on a suspect.
- Drag and Drop: Many levels require you to pick up environmental items (like a glass of water) and drop them on a character to provoke a reaction.
- Hidden Object Swiping: Sometimes you need to actively rub or swipe the screen to clear away fog, dirt, or obstacles obscuring vital evidence.
Gameplay Objectives & Progression
Progression is strictly level-based. There are well over a hundred tricky scenarios to burn through. You start with simple A/B choices and rapidly graduate to complex scenes with multiple interactable layers. The ultimate goal is to solve the puzzle on the first try without burning through your limited stash of hints. If you get completely stuck, the game offers a built-in help system that provides escalating clues or the option to skip the level entirely—though this comes at a steep price in either in-game currency or ad-watching.
Surviving the Ad Grind (The Real Meta)
Let's address the elephant in the room. While the puzzles in Who Is? are fantastic, the ad frequency is punishing. The current meta isn't just about solving riddles; it's about managing the game's economy to maintain your sanity.
Players frequently run into a highly frustrating UI quirk: the delayed "Next" button. After finishing a level, the button to proceed takes a few seconds to appear, often leading impatient players to accidentally click on a pop-up ad or a "prize wheel" reminder. Furthermore, unskippable ads often trigger after every single 30-second level.
The Ultimate Workaround: The smartest way to play is to aggressively farm the "escalating hint wheel." When the game offers you a chance to multiply your hints (2x or 3x multipliers), take it. By banking a massive reserve of hints early on, you can bypass the need to watch ads for clues on the much harder late-game levels. Alternatively, because the game does not require a constant internet connection to load core levels, the absolute best strategy for uninterrupted play is to play offline. Turning off your Wi-Fi or mobile data completely disables the mid-level ad injections, letting you burn through the detective scenarios at your own pace.
Pro Tips and Strategy Guide
If you want to clear the 100+ scenarios without rage-quitting, keep these actionable strategies in mind:
- Never Guess Blindly: The game will penalize you for random clicking. Always look for the interactive element (a drawer that opens, a rug that moves) before making an accusation.
- Farm the Multipliers: As mentioned, whenever the escalating hint wheel pops up, spin it. Banking 3x hints on easy levels is mandatory for surviving levels 50+.
- Look for Physical Inconsistencies: Suspects usually have a visual tell. Look for mismatched shadows, extra fingers, or items bulging in their pockets.
- Combine Items: If tapping isn't working, try dragging items onto each other. You often need to combine tools to break a lock or reveal a clue.
- The Airplane Mode Exploit: Boot the game, turn your device to Airplane Mode, and enjoy an ad-free experience. Note: You will not be able to spin the hint wheel or skip levels while offline.
Is Who Is? Safe for Kids?
Despite the cartoonish, colorful art style, parents should exercise slight caution depending on the child's age. The game frequently deals with themes of murder, infidelity, crime, and deception. You will be asked to identify "Who is the killer?" or "Who is cheating?". While there is no graphic gore or intense violence—everything is handled with lighthearted, PG-rated visual humor—the conceptual themes might require explanation for very young children.
There are no multiplayer communication risks, as the game is entirely single-player. However, if played with an internet connection, the aggressive ad network may expose children to unvetted advertisements for other mobile games. Playing in offline mode is highly recommended for younger gamers.

Who Is? is incredibly lightweight, designed to run smoothly on virtually any modern device. While it originated on mobile platforms via the BrowserGamers App (iOS/Android), it has been perfectly ported to Windows and web browsers.
