If you have not seen it yet, Google has an adventure game on the front page, which is really nicely done :)

If you don't know the url: www.google.com ;)

I'm probably blind as usual, I don't see anything out of the ordinary thou

See the picture... to start the game you need to click the "|>" Symbol that the flying robot is carrying :)

Seems its not on .com.au

no idea, I have only checked .de, .com and .co.uk

but you are right... com.au does not show it... can't you just click "Go to Google.com" in the lower left?

Clicking google.com doesn't help, it's just ... Generic Google page. I suppose it'll appear here sooner or later thou.

This game is probably for Google.com , Google.co.uk and Google.pl only.

Google has created one of its most elaborate doodles yet to celebrate the 60th anniverary of the first book publication by Stanislaw Lem, the Polish science fiction author whose works included the novel Solaris.
The Guardian

yay, I got it working under google.co.uk

Have fun... the puzzles are really simple but the animations are so nice :)

Yea I finished it already, the art style reminded me of Machinarium a lot. Thanks for the info, I wouldn't have noticed it otherwise :-)

Finshed here too, it also works on Google.es

It works on .hu too.
