Two colorful shape boards with one changed object highlighted

Ready to test your visual memory?

The board blinks and one thing is different. Three tries, and the board grows every time you get it.

Nothing moves and nothing leaves. Exactly one thing changes where it stands.

How to Play

  • Study the board

    Shapes in a grid, and a few seconds to take them in.

  • Watch it blink

    The board goes blank for a moment, so your eye cannot cheat.

  • Tap what changed

    One shape comes back a new color or a new shape.

What It Challenges

  • Visual working memory

    Hold a whole board in mind, not just one piece of it.

  • Attention to detail

    Notice the quiet difference, not the loud one.

  • Encoding

    Take in more of a scene in the time you are given.
