Free brain tests: speed, reaction and focus

Quick tests for speed, focus and attention

Brain tests turn a single skill into a number you can check and improve. How fast do you react? How many words do you type in a minute? How well can you ignore a distraction? Each test takes about a minute, gives you a clear result and saves your best score in your browser.

These are the kinds of tasks psychologists have used for decades to study attention and speed, adapted into short, fun challenges. They are not diagnostic or medical tools, but they are a good way to see how sharp you are today, and they are fun to compare with friends.

The tests

• Reaction Time: wait for the color to change, then tap. Five rounds give you a reliable average.
• Typing Test: type as many correct words as you can in 60 seconds.
• Aim Trainer: hit 30 targets as fast as you can, a favorite warm-up for gamers.
• CPS Test: how many clicks per second can you manage in five seconds?
• Stroop Test: name the ink color, not the word. A classic test of attention control.
• Schulte Table: find the numbers from 1 upward on a scrambled grid.
• Dual N-Back: track positions and letters at the same time. The toughest working-memory task on the site.

Getting reliable results

1. Use the same device each time. Phones, laptops and mice all add different amounts of delay.
2. Warm up first. Your first round is almost always your slowest.
3. Test when rested. Sleep, caffeine and time of day all shift your scores.
4. Look at the trend. One bad result means little. A steady improvement over a week means a lot.
