Tetris DS vs. the Guideline wrote:

TDS deviates from other compliant games in aspects like level counts, down key behavior, 20g, etc. For "follows closely", only TW would probably be eligible, as it itself defines the guidelines.

We know from the interview with Henk that the Guideline is revised annually: "We have a minimum bar that we create every year". Perhaps the ability to cancel lock delay by pressing Up or Down in the landed state was added to the Guideline between 2002 and 2006. And yes, Henk claims that TDS is guideline compatible: "So we do things like make sure we've got compatibility with the guideline, so people can migrate from mobile to the Nintendo version." --Tepples 23:44, 27 September 2006 (EDT)

Where in the sentence did it say "compatible" at all? The term in the article was "follows closely" not "compatible". The guidelines appears to include recommended but non-mandatory elements, as a game can be guideline "compatible" without B2Bs, T-spin recognitions or even scores (TGMA apparently lacks all of them). Yet while "compatible", such a game would not be following the guidelines closely as it could be doing. As far as that is concerned, is the sentence even necessary? We have no means to know with certainty whether a certain idiosyncratic feature is an allowed deviation from the guideline, an updating of the guideline, or a mere oversight (or whether even certain elements are supposed to be non-mandatory.)

i sort of agree. in the interview, henk didn't even know if nintendo included t-spins. there's no telling how much a licensee goes by the books and how much he deviates. i too think tetris worlds and deluxe, the last games made by BPS, must be the most accurate. 02:02, 29 September 2006 (EDT)

T-spin shrinking

PTet.png is intended to be used in T-spins, and many T-spin setup articles use it. So each of the four minoes in T must shrink on T-spin.

PTet is supposed to be a multi-purpose image. No Tetris game I've seen shrinks the four minoes for the T on a T-spin. 11:34, 21 August 2017 (PDT)
If you check original upload in, it says "Possible alternative for T pieces in T-spin setup pages.".
However, it has since evolved into a multi-purpose File: File talk:PTet.png 11:49, 21 August 2017 (PDT)
Just by you? ... You didn't make PTet, you know...

And look at the great amount of articles that use PTet for T-spins. This means that T-spin shrinking is real!

T-spin shrinking is just notation. Plenty of T-spin articles don't use P. 11:58, 21 August 2017 (PDT)
You call a different block style notation?
Rotation centers are notation. Arrows are notation. T-spin shrinking is notation. None of these appear in the game. 12:19, 21 August 2017 (PDT)
Rotation centers and arrows are symbols. Small is a style of block.
So is SRS / ARS / The New Tetris / Game Boy. Small block styles are to emphasize the current block. 12:28, 21 August 2017 (PDT)


Some of the rules used to be not mandatory in Guideline, and only 2 hidden rows were needed, until the anonymous user changed it!

No, from what I can tell, there are 20 hidden rows, and there must be 3 next pieces. 04:51, 30 August 2017 (PDT)

NullpoMino uses 3 hidden rows in its STANDARD rule. And many Guideline games don't have Katjusha or Kalinka.

That was 2002. 05:02, 30 August 2017 (PDT)
If that would be the case, then NullpoMino would have switched default. Also note the row "Known guideline version" and see that non-2002 guideline games also may not have these songs.
Sometimes, they may break a trait shared by many other guideline games --a lot of guideline games may have Katyusha/Kalinka. It's hard to explain it. 05:26, 30 August 2017 (PDT)
Yeah, the guideline does include non-mandatory elements, so we think they are mandatory. 05:27, 30 August 2017 (PDT)

Found it!

I found a download url for the guideline in its entirety (19.87 MB): guideline docs 12:12, 10 September 2017 (PDT)

Leaked 2009 version of the Guideline

This *other* Tetris Wiki's Guideline page ( ) has a download link for 3 files that appear to be the 2009 version of the Guidelines (Tetris Design Guideline, Tetris Marketing Guideline, and Tetris Variant Concepts) (I think it's also the link mentioned above). Would it be acceptable to include information from these files in this page? User670 06:25, 22 August 2019 (PDT)

As long as you don't include any copyright material you should be fine. --Simonlc 14:23, 25 August 2019 (PDT)
