There is only like a 5 second gap until the buzzer so if you have fast internet (which I do) and can very quickly search for the key phrase out of the question to get a direct readable hit from the Google search preview, then yeah you could cheat.
But obviously that is something that won't work for every question. And they have been wording questions in a way to not make that easy. You also get more points by answering faster.... soo...
Your best bet of cheating the system is to load up your living room with all your smartest friends and hope you make the mob/One.









(i think, not checked my points yet)
