After lowering the water level, there is a anticube room beneath the first warp zone. In New Game+ first-person view mode, the Polytron logo shows on the floor. After following the treasure map (standing exactly in the hole of the logo, entering the tetromino code on the reverse side), a floating black monolith/obelisk/pillar appears. What is the trick?

  • A lot of the research around this puzzle involve the Tome. My guess is that it must be read like a manga, with the big letter being the key to a Caeser sipher for the next page. I'll look into it and come back with the results... It might be something else since the distribution of letters seems to match that of the english language. Commented Apr 15, 2012 at 19:24
  • Yes, but if you read it like a japanese book (start with the end) every page has a big letter. Commented Apr 15, 2012 at 21:57
  • @Gimlao Interesting idea, I've tried using 0 as LT and 1 as RT in both big indian and little indian without success. I think the answer must have 8 commands like every other in the game, but who knows? Commented Apr 15, 2012 at 22:49
  • It's possible you need to stand on the other center (With the #1 on it) and input the 8-step code. The eight pages only utilize five characters (instead of the full six). They match the red cube artifact. It's also possible that each big character is a direction or step. P-S-K-S-K-B-C-B is what the big letters translate to [or B-C-B-K-S-K-S-P]. Given that you can't use left or right to leave that center square, I imagine the five letters translate to RB, LB, Up, Down, A. Tried a few combinations while standing on that second square... thus far I know it doesn't start with an Up, Down or A.

  • Maybe altering the brightness or sound settings?

As discovered by a person on the Xbox360Achievements forum in this post, this puzzle can be solved just like the first puzzle in the same room. The following picture shows the floor of the room, which can be seen in first person view:

The first puzzle required a button input sequence while standing on the square with no line in it (circled in blue in the picture). This puzzle similarly requires standing on the square with a line in it (circled in green in the picture) and inputting the following button sequence.

down down LT RT RT A up

    Great! But also slightly sad. It looks like this was finally brute forced out, I really want to know how it was meant to be fixed.

    @Keith I agree, but I followed the solving effort for a little while and it looked like someone related to the company was giving out hints (which led to this discovery) and he said that the answer could not be found in game. There was some speculation that the answer would be in the soundtrack, but I don't think it has been released yet Commented Apr 18, 2012 at 23:09
  • @murgatroid99 You're right, it comes out on April 20th. disasterpeace.com/album/fez Commented Apr 19, 2012 at 0:06

    I am appalled that the answer to this puzzle was not in the game. For a puzzle game with so many awesome puzzles, this was pretty damn lame. If it turns out it is just well hidden I'll retract my scorn, but for now. Boo!

(To make the black monolith first appear, follow the burnt treasure map; or just stand atop the square on the left and enter ↑ RT ↑ A ↓ LT ↑ ↓.)

Now, stand atop the square on the right and enter: ↓ ↓ LT RT RT A ↑


The black monolith turns into a heart piece (finally), thanks to gregSTORM.


gregSTORM used assisted brute force to discover this solution. It's still unclear how the puzzle was actually supposed to be solved. See "How is the Monolith puzzle in Fez supposed to be solved?" for links to some threads that discuss possibilities.
