Hint Welcome to the Hacker Test 2.x! Before you start, please read the What's new in version 2.x section.
So here we go! This is page number one. That should be pretty obvious, because it has the numeral “1” above. But there's a problem... There is no link to page 2! How on earth will you find page 2 without a link taking you to it? You have to think like a hacker! To get to page 2, you'll have to enter the key to the next page made up by analogy with the current page key. Enter it and try to “crack” the page. If you're right, you'll get the next page. If you're wrong, you'll get an ugly error message. It's as simple as that.
