Today’s Google Doodle (screenshot below; go to link to see it) allows you to mix a witch’s brew.
As c|Net reports:
Users can combine various ingredients to play mini games, from whack-a-mole with the undead, to a shell game where your goal is to find a mummy in a coffin. There are several others, which can be found with experimentation.
That’s about all you can do with this one, so if you’re looking for an ending, it’s a bit of a cliff-hanger.
I haven’t tried it (work calls), but if you’re indolent and ready to play, report back.
