After you have pressed Start, you will see a page
with a series of letters (you know, from the alphabet). Memorize these
series. When you are done memorizing, click on Proceed. You are
transferred
to a new page, that features the same series, except for one letter. Click
on the letter that is missing on the alphabet hyperlinks in the grey box
on the bottom of the screen. If false, try again. If correct, you are
transferred to the next level. As you proceed, the series will get
larger, and thus harder to remember... At the end is a reward!
Now, press Start to begin...
