Should I answer the word or its position?
Always answer the word's meaning. Ignore whether the word appears on the left or right side.
Are standard trials balanced?
Yes. The 20 trials contain five examples of each word-and-position combination, shuffled every run.
What happens after a wrong answer or timeout?
Standard mode records it and continues to the next trial. In endless mode, either event ends the run.
How does endless mode get harder?
The response window begins at 1,800 milliseconds and falls toward 350 milliseconds as your streak grows.
Can I play on a phone?
Yes. Use the two large touch buttons. Keyboard players can use the arrow keys or A and D.
Is this a medical or psychological test?
No. It is an informal browser game and cannot diagnose any medical, neurological, or psychological condition.
