  2. Oh thanks..this was v interesting:). Initially it was confusing, but then I got the hang of it. Funnily my timing is same in both XVs- Truth or Lie it's 14+mins.

  3. Very confusing at first. I broke it twice yesterday. Came back to it today with a fresh mind and solved it in 8:49.
    Nice idea.

  4. 9:15.Nice one. Like others had noted, I was also confused at the start with the converse part as to whether the absence of Xs and Vs denote the absence in adjacent cells of 10 & 5 (OR) 9,11 & 4,6. But I understood that it is the latter through box 7

    1. Thanks Kishore. I felt it would be an interesting concept of having the liar rules with XV rules and also having the converse rule apply. Glad you liked it
