Odd One Out Rush
A crowd walks onto screen — one prompt flashes ('Who is a robot?', 'Who stole the cake?') — tap the imposter before time runs out.
Each round drops a tiny scene of similar-looking characters with one anomaly; tap the suspect that matches the clue to score and chain combos.
One thumb: tap to accuse the imposter.
Social-deduction brain puzzles in the Who Is? / Brain Test vein — mini crowds, micro-clues, one liar.
