(8 Letters) Adult Male Horse

S - N - A - L - L - I - O - T... Snalliot!

(4 Letters) Machines Found in Las Vegas

S - L - I - T... Slit machines!

Good god, playing against the AI is torture.  To make it seem more human it will occasionally get answers wrong, but only by transposing key letters or substituting wrong vowels.  And it's pretty easy to guess the correct answer once you've seen the wrong answer.

(Although I think they should have accepted slit machines; I'm pretty sure Vegas has enough of those.  Just probably not as many as the predominant answer.)

What in the good lord's name are you talking about?

EDIT: oh, it's a bad game. I get it now. Carry on.
