James Clapper has been playing it all week.
He's really good at it, but still no nearer catching Snowden.
He finished the US level by collecting 98,000,000,000 phone calls and emails.
He finished the Hong Kong level by accidently mis-spelling Snowden' name.
He finished the European level by accidently stopping the wrong plane.
He finished the South American level by managing to piss off almost everyone, everywhere south of Mexico.
He's currently stuck in the Russian level. He's tried threatening, begging, bribing, calling off summits, but he just can't get past the level boss - Putin.
