You Really Have To Pay Attention!!!
Read the instructions below, before you start (unless you can read Japanese!).
This will drive you nuts.
In English, the instructions are as follows:
1. Touch 'start'
2. Wait for the 3, 2, 1.
3. See & Memorize each viewed number's position on the screen, and then
click (from memory) each blank circle from the lowest number to the highest
number.
4. At the end of game, the computer will tell you the age of your brain.
5. Forward the message and type your calculated age in the subject line.
Good luck!
