These old scenes look normal — but one thing is from the wrong century.

Sunglasses in a Dinosaur-Era forest.
A drone above a medieval castle courtyard.
A wireless keyboard in a 1920s café.

Each vintage, sepia-toned illustration hides a single modern object that hadn't been invented yet in that era.
The modern item is drawn in the same sepia tone as the rest, so you can't spot it by color alone — you have to recognize its shape.

This is a simple observation quiz where you tap the modern item that shouldn't exist in that era.
Dinosaur times, Stone Age, Ancient Egypt, Greece, Rome, Vikings, Medieval Europe, Renaissance, Age of Sail, Baroque, Victorian, Wild West, 1920s, 1950s-70s —
17 eras, 100 questions of anachronisms hidden in time.

How to play is simple.
・Look carefully at the sepia scene
・Tap the modern item that doesn't belong

"Wait, is that a smartphone?" "No way, drones didn't exist in medieval times!"
The thrill of catching objects that slipped through time is addictive.

Hints gently suggest the category and use of the modern item, so you won't get stuck.
History and the present collide in this adult brain-training puzzle.

So — don't let that anachronism slip past you.
