Level: One day in 1990
Passing conditions: Find 12 discords
Answer: Ragdoll cats, selfie sticks, smartphones, vacuum cleaners, warning signs, modern games, LED screens, battery cars, Bluetooth headsets, solar panels, drones, and high-speed rail.
1. You can see the high-speed train in the upper left corner, and you can find solar panels on the top of the roof. Then click on the desktop inside the room and a modern game will appear. The little boy in green clothes is holding a selfie stick.
2. The little boy next to him is wearing a Bluetooth headset. After that, the player needs to click the big goose three times to find the phone. The cat in the lower right corner is a Ragdoll cat, and the uncle selling popsicles is riding a battery car. These are all comparisons. Easy.
