We’re allowed to be completely silly on a Friday afternoon, heading into a weekend that marks the end of summer, aren’t we?

The instructions on this website are in Japanese. In English, here’s what you do:

1. Click on “start.”‘
2. The game will count down “3, 2, 1,” and then start.
3. You’ll see a few numbers. Remember the order of the numbers, from lowest to highest.
4. The numbers will then disappear and be replaced with circles. Click on the circles in the order of where the lowest to highest numbers used to be.
5. At the end of game, the computer will tell you the age of your brain.

We’re not sure if you’d rather have an old brain or a young one — what matters more? energy or experience? — but at least you’ll know.

Enjoy both the game and the holiday.
