I have here a simple binary-like pattern, consisting of crosses (X) and circles (O).

O X X O X O O X O
X O X X X X O O O
X X O O X O O X O
O X O O O O O X X
X O X X O X X X X
O X O O O O X X O
O X O X X O O X O
O X O X O X X O X
O X O O X X O X O

There is, however, a hidden sequence that makes the pattern complete when it is orientated in a different way. So, what is this missing sequence?

HINTS (Level 1):

When the pattern is orientated in this "different way", each sequence is unique. Meaning, there should be no repeats.


The missing sequence should fit snuggly "in the middle" of the new orientation.


The missing sequence is nine (9) characters long.


The number 14 should appear a lot… so should the number 42. But 14 is more important.


HINTS (Level 2):

Did I say "long"? I never said the sequence was linear, did I?


Perhaps if we played a different game, the pattern would make some more sense?


"Unique" should suggest the current pattern has some overlap.

  • $\begingroup$ … I would place X into 4/5 and 6/5, otherwise I don't see what else should be missing. I would add something like (X O X X O X O O O) or (X O X O X O X O X), but only by random "it fits" my ruling. $\endgroup$ – Jan Ivan Dec 12 at 11:31
  • $\begingroup$ I assure you randomly fitting an arbitrary sequence or padding random X's or O's will not produce the answer efficiently; I'm well aware of the 512 possible sequences, but if you follow my hints judiciously it should narrow the options down to one. However, if you can convince me (with solid reasoning, mind you) that there could be another viable solution, by all means, feel free to argue your case! $\endgroup$ – Omicron Zed Dec 12 at 16:56
