Google's new game that has you build Rube Goldberg-style contraptions is a total viral ploy. We wanted to hate it for that. But we can't, because it's just that fun and addictive.
It's a little bit like Cut the Rope, but you build the tools to get your balls to the target yourself. Yeah, it's a blatant Nexus promo, but I still managed to spend my entire lunch break playing. Good luck.
