Do you have 3D glasses? Red-green, red-blue and red-cyan glasses all work.

How deep?
Less depth is easier on the eyes. More depth pops out more.
1. Hide the green bar
Put the glasses on and cover the eye behind the green lens, so you look only through the red lens. Slide left until the green bar disappears.
2. Hide the red bar
Now cover the eye behind the red lens, so you look only through the green lens. Slide left until the red bar disappears.
3D mode is just a fun way to play. If your eyes feel tired, take a break or play without glasses.
HOW TO PLAY
Each journey has 6 questions about the wonders. Drag the picture to spin the models round.
Some questions show one wonder: pick its name or its country from the buttons.
Some show two, three or four wonders: tap the right one, or tap them in order from oldest (made longest ago) to newest.
No mistakes gets ⭐⭐⭐. Every wonder you get right the first time sends you its postcard, with facts to read.
HOW 3D WORKS
Try this: look at your finger with one eye, then the other. It jumps! Your brain uses the jump between your two eyes to see depth: stereo vision.
The game draws the wonders twice, from two eyes a little apart, in red and in green (or blue). The glasses give each eye its own picture, so the buildings stand up in front of you.
The people who built these wonders had no computers. They planned them with drawings, string, measuring rods and clever maths, then moved enormous stones with ramps, rollers, levers and a lot of people working together.
