Tetracubes

Tetracubes have an interesting property: any of them can be "doubled" using the full set of 8 unique pieces. See, for example, http://www.mathematische-basteleien.de/tetracube.htm#Magnification%20Problem. I think, it's worth to mention in the article. —Preceding unsigned comment added by Mikhail Ryazanov (talk • contribs) 05:01, 31 October 2010 (UTC)[reply]

I thought that all polyominoes, including tetrominoes, are two-dimensional shapes composed of squares. Some of the "tetrominoes" in this article are three-dimensional and composed of cubes. —Preceding unsigned comment added by 208.58.249.130 (talk)

I've cleaned up most of the confusion between tetrominoes and tetracubes. Any left? --Damian Yerrick (☎) 03:08, 23 July 2006 (UTC)[reply]

Colour variations in different Tetris games

I like Tetris as much as the next guy, but I don't think this article benefits from a table showing how different versions of Tetris colour the Tetronimoes. That doesn't have anything to do with Tetronimoes in general so shouldn't be in this article in my opinion. Pelago 15:18, 17 May 2006 (UTC)[reply]

Feel free to kick the table out to one of the gaming wikis, such as Tetriswiki. --Damian Yerrick (☎) 03:08, 23 July 2006 (UTC)[reply]

should the grids be a part of this article?

Article content

There's conflicting information in this article. In the "The seven tetrominoes", it says S is a free tetrominoe, while in the "Tiling the rectangle and filling the box with 2D pieces" it says Z is a free tetrominoe. The organization of the content also does not coincide with the organization of the images; they're not in the same order as one would except to see while reading. —Preceding unsigned comment added by 74.75.27.41 (talk • contribs)

S, N, and Z are all names for the same free tetromino. I just clarified this in the article. --Damian Yerrick (talk | stalk) 15:48, 18 November 2008 (UTC)[reply]

Chiral

The link on this page to the article "Chiral" redirects to a disambiguation. Can anyone fix this? I would really like to do it my self, but I myself have no idea which chirality I should be linking to. —Preceding unsigned comment added by 217.136.53.224 (talk) 21:46, 4 December 2009 (UTC)[reply]

Origins

Why is there no information on the origin of tetramino??? As a concept and geometric idea, it had to be conceived by someone somewhere. Is this knowledge not yet known in this day and age? Laval (talk) 07:29, 30 October 2011 (UTC)[reply]

Move of Tetromino to Tetrimino

Tetromino was recently moved to Tetrimino. As far as I know, the former is the term used in geometry (and it's also consistent with Pentomino, Polyomino etc), while the latter is used in Tetris. I'd say the article should be moved back since it covers the general concept (of course with references to Tetris), but I'd like more input before doing the move. --ἀνυπόδητος (talk) 11:55, 6 November 2011 (UTC)[reply]

A Google search supports your contention: "tetromino" seems to be by far the predominant term, and mentions of "tetrimino" occur almost entirely in association with Tetris. Unfortunately I do not find either term in a dictionary. The former is also the term used in Polyomino. I would suggest that you have a strong case, and will get support to move it back.

Here's a link: Google book search for Martin Gardner's original article on this suggests "tetromino". It is also worth mentioning that the original tetrominoes do not have 7 pieces, as the chiral pieces are not duplicated. But maybe mathematics, subject to fashions and fads like everything else seems to be, has had the rules changed. sorry, that has been mentioned. — Preceding unsigned comment added by WestwoodMatt (talk • contribs) 14:37, 6 November 2011 (UTC)[reply]

I agree it should be moved back. "Tetromino" is by far more the standard spelling in mathematics. —David Eppstein (talk) 16:20, 6 November 2011 (UTC)[reply]

I've moved it back. I've also changed "Tetrimino" in the article to "tetromino" everywhere (note both spelling and capitalization). Ozob (talk) 16:42, 6 November 2011 (UTC)[reply]

Tetris copyright

It says that the Tetris Company has a copyright and trademark on the shapes. I'm pretty sure it has neither. I believe it has a trademark for the name Tetrimino rather, and has won a lawsuit on the basis of trade dress (meaning colors and style of Tetrominos). While I don't know the specifics of the law, I'm pretty sure that doesn't mean it has either a trademark or copyright on the shapes. 96.127.226.229 (talk) 07:07, 17 September 2016 (UTC)[reply]

Actually, it has won several lawsuits on the idea of tetriminoes, the shape, color, etc, and eventually copyrighted and trademarked all aspects. 108.66.232.14 (talk) 03:05, 14 February 2017 (UTC)[reply]

To make a long story short, the Tetris Company has one of those rare "concept" copyrights. The idea of tetriminoes is copyrighted to them. 108.66.232.14 (talk) 03:05, 14 February 2017 (UTC)[reply]

We can report what independent reliable sources directly say about Tetrominoes. We call this "verifiability". It is one of our 5 pillars. - SummerPhD^v2.0 03:09, 14 February 2017 (UTC)[reply]

Tetromino → Tetrimino – Official name 108.65.81.68 (talk) 01:00, 17 October 2016 (UTC)[reply]

Oppose as ridiculous. Tetrominoes are a special case of polyominoes. The Tetris Company can use whatever name they like, but that is no reason for us to abandon standard polyomino naming conventions. Ozob (talk) 02:04, 17 October 2016 (UTC)[reply]
Oppose and speedy close per WP:COMMONNAME, WP:RIGHTGREATWRONGS, and WP:NOR. Nobody actually calls them that. Or, more precisely, there are a few low-citation papers on Google scholar that use that spelling, perhaps as a typographical error, but about 10x as many that use the same spelling we do. —David Eppstein (talk) 02:30, 17 October 2016 (UTC)[reply]

“Filling the box”

I have to ask, what is the encyclopedic interest of the “Filling the box” sections? —67.14.236.50 (talk) 22:42, 15 June 2017 (UTC)[reply]

Tetracubes - Blockout

Since Tetris was mentioned as an example for the usage of tetrominoes, the we might want to mention Blockout for tetracubes. I'm not a native english speaker so this may be done by someone else :) --Bunny99s (talk) 01:40, 26 April 2019 (UTC)[reply]

Tetracubes

The Left Screw and Right Screw tetracubes are the same, just reflections of each other. 62.49.112.248 (talk) 17:57, 20 November 2024 (UTC)[reply]
