Memory Cube 3D
Tap a card to turn it over. Drag to turn the cube.

Do you have 3D glasses? Red-green, red-blue and red-cyan glasses all work.
You can change this any time from the menu.

Check the 3D

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

  1. Every card has a partner with the same picture somewhere on the cube, maybe on the other side!
  2. Tap a card to turn it over, then tap another. If they match, they stay open. If not, they turn back, so remember where they were.
  3. Drag to turn the cube and look at all six sides.
  4. Find every pair in as few turns as you can for ⭐⭐⭐. Coins buy new picture sets.
  5. Memory tip: say the picture and the side out loud, like "dog, on the top"!

HOW 3D WORKS

  1. Try this: look at your finger with one eye, then the other. It jumps! Your brain uses the jump between your eyes to see depth: stereo vision.
  2. The game draws the cube twice, from two eyes a little apart, in red and in green (or blue), and the glasses give each eye its own picture.
  3. Memory science: your brain is very good at remembering where things are. Long ago, memory champions remembered long lists by imagining each thing in a different room of a house. Remembering cards on the sides of a cube uses the same trick!
