What it trains

Why match shapes at speed

You have to keep the previous shape in mind, compare the new one with it and answer right away. The higher the level, the more features you have to check, and the non-matching shapes often differ in just one of them.

You get distracted and lose the threadEach new shape has to be compared with the last one
You answer fast but make mistakesA mistake costs a point and drops your level
You want a short warm-upOne minute and the round is over
You mix up similar thingsSometimes they differ in just one feature

Decision speed

In one minute, the faster you compare, the more answers you give.

Short-term memory

Hold the previous shape in mind while you look at the new one.

Comparing features

Shape, color and fill are checked together.

Accuracy

A mistake costs a point and breaks your streak.

Rules

How to play

Start
Press “Start”. The first shape appears; just memorize it.
Compare
Then shapes come one at a time. Compare the new one with the previous one: same or different?
Answer
Press “Yes” or “No”. On a computer you can use the arrow keys: ← no, → yes.
Level
Six correct answers in a row move you up a level: first only shape matters, then color, then fill. A mistake drops you one level.
Score
A correct answer earns as many points as your current level, and a mistake costs one. After one minute you’ll see your result.

Method

What the exercise is based on

Comparing the current item with the previous one is a simple format for processing speed tasks. Here difficulty grows through features: the more of them there are, the more carefully you have to look.

If you want to hold more than one step back in memory, try N-back. And Shape Rotation adds comparing shapes while turning them in your mind.

Who it’s for

What counts as the “same” shape?
