Whooo

Whooo is a digital deduction and elimination puzzle based on the classic "Guess Who" logic. The technical core involves "Attribute Filtering," where players must systematically narrow down a pool of secret characters by identifying unique physical features. It is designed for trivia and logic enthusiasts who enjoy social deduction mechanics and want to sharpen their ability to distinguish specific visual traits under competitive pressure.

At the start of a match, both you and your opponent are assigned a secret character. Your goal is to identify their character before they identify yours. Interaction involves asking "Yes/No" questions from a provided list (e.g., "Do they wear a hat?"). Based on the answer, you must tap to "flip down" all characters that do not match the description. The game culminates in a final guess once the pool is reduced to a single candidate.

Maximizing deduction efficiency depends on "Binary Splitting." Instead of asking about rare features, choose questions that split the remaining character pool as close to 50/50 as possible. A pro strategy is to "Listen for the Logic"—observe which characters your opponent is flipping down to gauge how close they are to your secret identity. Winning in the fewest turns possible yields a "Master Detective" multiplier.
