Online attention game

Find two identical shapes: among similar patterns only one pair matches

Also known as: Two of a Kind, find the identical ones, find the matching pair, find the twin

The field is filled with patterns of colored cells. They’re all different except for two. Find that pair and tap both shapes. At first the patterns differ noticeably; at the higher levels, by just one or two cells. A round lasts a minute and a half.

What it trains

What finding identical shapes trains

To find the pair, you compare the patterns piece by piece: where the filled cells are and what color they are. The exercise teaches you to hold one pattern in memory and quickly check it against the others without losing track of where you’ve already looked.

When every pattern differs from a common template by just one or two cells, comparing them “as a whole” no longer works, and your attention shifts to details. Your results show how many pairs you found and how many mistakes you made.

Attention to detail

Patterns differ by one or two cells.

Visual comparison

You compare the patterns two at a time.

Working memory

Hold one pattern in mind while looking at another.

Accuracy

A wrong pair costs a point.

Rules

How to play

  1. Start

    Press “Start”. Patterns of colored cells appear on the field.

  2. Look for the pair

    All patterns are different except for two. Compare the position and color of the cells.

  3. Pick both

    Tap the first shape, then the second. Tapping the same one again deselects it.

  4. Mistakes

    A wrong pair costs one point. After a second mistake on the same field we show the answer and the level drops by one. Two fields in a row without mistakes raise the level.

  5. Results

    After 90 seconds we show your points, pairs found, mistakes and highest level.

Two of a Kind

Among similar cell patterns, exactly two are identical. Find them and tap both. There are more and more patterns, and the differences get smaller.

Method

What the exercise is based on

The exercise resembles the classic pattern-matching tasks used in attention tests: find the exact copy among the options. The more options there are and the less they differ, the longer the search takes.

So the levels grow in two directions: more patterns on the field and smaller differences between them. If you’d like to practice remembering pairs, try “Find the Pair”.

Questions

Frequently asked questions

How are points counted?

Each pair you find is worth as many points as your current level, from 1 to 7. A wrong pair costs one point. Your score never goes below zero.

How do I undo a selection?

Tap the selected shape again and the frame disappears.

How can I search faster?

Pick one noticeable detail, such as a filled corner, and narrow it down to the patterns where it’s the same. Then compare the remaining cells among those.
