## One Brain Description
One Brain is inspired by the Stroop effect, a famous psychological test that measures how well you handle conflicting information. For example, it's harder to name the color of a word when the word itself spells a different color. This game challenges your whole brain as you fight to process the mixed signals and make the right call before time runs out.

Game modes:
• Colors: Does the word match the color it's written in?
• Arrows: Is the arrow actually pointing the way it says it is?
• Numbers: Is the math equation true or false?
• Words: Which word matches the definition?

How high can you score under pressure?

## One Brain Reviews in United Kingdom

### **--- "Not appropriate for non touch screens"
It isn't possible to move the curser quickly enough. With some adjusting it would be much better.
-- JL0837, 2024-03-27

### *---- "Great"
If it worked !!!!!
-- People's Bizness, 2024-03-20

### *---- "Dreadfully poor"
The game has no facility toadjust difficulty levels.  The time 'allowed' for submission of an answer is ridiculously short. A very poor game and a waste of time - it will be deleted immediately.  Very telling, when trying to submit this comment, is the fact that 'nicknames' such as Useless, Pathetic, and Awful have all been used before ! That tells you something. In fact, i've just discovered that NO WORDS ARE AVAILABLE ! Obviously don't want to know just how pathetic this game is
-- topspoon, 2024-03-12

### *---- "grrrrr"
make the timer a little bit longer
-- Sneaker-head_, 2023-07-30

### ****- "Good"
Good for a free game
-- jinnty67, 2023-01-28

### *---- "NEED MORE TIME"
NEED MORE TIME ALSO NEED MORE QUESTIONS TOO BORIIIIIIIIIIIIIIIIIIIIIING
-- rainbow dog pup hooman, 2023-01-23

### ***** "one brain"

-- ChristieCap, 2021-11-24

### ***** "review"

-- saathnibhaanasaathiya2, 2021-10-15

### **--- "dont download"

-- ratasha garden, 2021-09-19
