Those Googlers are apparently having quite a bit of fun with their new Google Phones (aka Nexus One). From the looks of it, they’ve set up some sort of holiday game that’s a twist on the game memory. But the catch is that you can only access this game from the Nexus One, any other device will be forwarded to the standard Android homepage.
Welcome to Nexus One!
For some festive fun, we’ve put a new twist on a classic game: “Memory”
Click on “Start Game” and you will have 5 seconds to memorize the placement of 12 pairs of cards. After 5 seconds, the cards will be flipped face down.
Your goal is to find all 12 matching pairs as quickly as possible
Just tap on a card to flip it over
Continue flipping cards until all matches are found
Digging into the code of this page reveals that it is in fact sniffing to see if your device is the Nexus One. If not, it does the redirect.
Update 2: Of course, if you really want to trick the sniffer into thinking you’re on a Nexus One when you’re not, you can do that too. Andy and Emmanuel both point out that you can easily spoof the user agent and play the game to your heart’s content. For example, in Safari 4 if you have developer tools enabled, go to Develop -> User Agent -> Other and type ‘Nexus One’ in the box.
You can do it in Firefox by typing ‘about:config’ in the address bar and filtering on ‘useragent’ and setting it there. It’s apparently not quite as easy to do with the Chrome dev tools.
