About this game
A party hall, a park, a train platform — in a scene full of people, only one answer is hidden.
"That person looks suspicious..."
"No, wait — look at those shoes."
The longer you stare, the more you doubt. But the clock won't wait.
This is an observation puzzle where you reason from the clues drawn in a single picture — "Who did it?" "What's off?" — and tap your answer within a 12-second time limit.
Mud on a shoe, a stain on a sleeve, a tool in hand, the spot where someone stands —
every detail is your evidence to narrow down the truth by logic.
50 questions with a twist that first impressions alone won't crack.
The stages are everyday scenes that work anywhere in the world — gardens, plazas, cafés, harbours.
From 6 to 9 people, or rows of look-alike objects, you pick the one and only answer.
The further you go, the smaller and trickier the clues become.
How to play is simple.
・Scan the whole scene quickly
・Reason out the answer from the clues
・Tap that person (or spot) within 12 seconds
Get it right, and you're the detective of the hour.
Miss it, and one more look makes you nod — then you're hooked on the next.
Speed, observation, and deduction — your "smarts" show with every round.
So, can you see the truth in 12 seconds? Give it a try.
The game supports both button controls and touch controls, allowing you to play in TV mode, handheld mode, or tabletop mode.
