About this game

Feature Field is a search game. A key shows a shape and a line angle, and you scan a field of panels to find the one whose mark has both features. Panels with only one match are decoys.

It is based on conjunction search, a kind of visual search where the target is defined by a combination of features. It is harder than looking for a single feature, and it shows how attention combines information.

How to play

Look at the shape and the line angle on the key.
Scan the panels for the one that matches both.
Tap it before time runs out. Fields get busier as you improve.

Tips

Check the shape first, then check the line angle.
Rule out panels that match only one feature and move on quickly.
Scan in a steady pattern, like left to right, so you don't search the same area twice.

How it adapts

Kids get smaller fields and more time. Teens and adults get larger fields and shorter time limits. The size of the field adjusts to how you play.

Questions

What is conjunction search?

It is a visual search where the target is defined by two or more features together, such as a particular shape at a particular angle.

Why is it slower than finding one feature?

Because you have to check each candidate for both features, and that takes more attention.

Do the decoys matter?

Yes. They look almost right, and ruling them out is the main challenge.

The research behind it

Conjunction search is a well-studied part of visual attention research. Practice makes you faster at this game's version of it; we make no claim about everyday search.
