Task Instructions

In this task, you will see a series of numbers appear on the screen one at a time.

Your job is to add each new number to the number that came immediately before it and click the sum.

Example:

If you see "3" followed by "5", you would click "8"

3 + 5 = 8

Then if "2" appears, you would click "7"

5 + 2 = 7

Numbers range from 0 to 9, and no sum will be greater than 18.

Scoring & Levels

You earn 1 point for each correct answer. Incorrect answers or missed responses do not affect your score.

The task has three levels:

Level 1 3 minutes — numbers appear every 3 seconds
Level 2 5 minutes — numbers appear every 2 seconds
Level 3 Up to 10 minutes — numbers appear every 1.5 seconds

After Level 1, the task will seamlessly transition to Level 2 without warning. A 2-minute break separates Level 2 and Level 3, followed by a 15-second countdown before Level 3 begins.

Important: During Level 3, you may choose to quit at any time. However, your final score depends on your performance, so try to continue as long as you can.
