Ok, it's not the same without Alex, but it is fun! I mean, playing against IBM's Watson! Just like Jeopardy!... well almost.
First, you don't run out of time! There is no ring device, it's only you and Watson! If both contestants gives a wrong answer... the only one who gets punished it's you! not Watson!! And there's no money for the winner! So we play for fun!
As an English learner, it is a really difficult contest (What is a Cheez Whiz? now I know it's a thick processed cheese...) but it is still a funny way to learn and practice English language!
