Computational complexity[edit]

I think that the section of computational complexity should be made bigger.

Check this page: There is a lot of information about tetris complexity, like ways to create board configurations, some variants of tetris that are undecidable, etc.

Also, recently appeared a document in arxiv that claims to have solved an open problem about tetris:

what do you think about it? — Preceding unsigned comment added by (talk) 16:22, 26 June 2015 (UTC)

An Ip keeps trying to add that it is illegal for someone under 13 to play Tetris. That is not what the sources say. The sources provided only discuss the privacy policy and what a tetris website will do with information, nothing about whether it is legal or illegal to play. Along with that edit they are changing a bunch of links so they go through redirects or to red links rather than to the actual article name. -- GB fan 16:48, 13 October 2016 (UTC)

By the way, you exceeded 3 reverts. (talk) 16:53, 13 October 2016 (UTC)
I have not not exceeded 3 reverts, I have made 3 reverts. You have made way more than 3 reverts. -- GB fan 17:05, 13 October 2016 (UTC)
Also, as of 2013, it is illegal for players under 13 to play Tetris. This is to comply with the COPPA. (talk) 16:53, 13 October 2016 (UTC)
This is why new Tetris games ask you for your age, 0 to 120. If you enter a number under 13, you cannot play Tetris. (talk) 16:55, 13 October 2016 (UTC)
It is not illegal for some one under 13 to play Tetris. Illegal means that someone could be prosecuted for doing it. A 12 year old can not be prosecuted for playing Tetris. -- GB fan 17:05, 13 October 2016 (UTC)
It says that players under 13 can no longer legally play Tetris as of 2013. (talk) 17:08, 13 October 2016 (UTC)
Which source says that they can not play it, I didn't see that in either one of the documents. Even if the Terms of Service or the Privacy did say that, it doesn't make it Illegal as you put into the article. -- GB fan 17:10, 13 October 2016 (UTC)
Here. (talk) 17:15, 13 October 2016 (UTC)
To begin with that is facebook, not a reliable source. Next it is not for the generic Tetris game which this article is about. That is only for the specific Tetris Blitz game by EA. I very much doubt that what it says is true as it is not illegal to for a 12 year old to play the game. -- GB fan
That also applies to the rest of the EA Tetris games, as of 06.28'13. (talk) 17:20, 13 October 2016 (UTC)
Whom ever wrote that is playing very loosley with the term illegal. A complay can not make something illegal, only a government can. -- GB fan 17:25, 13 October 2016 (UTC)
They did that because of a 06.28'13 change to the law. (talk) 17:26, 13 October 2016 (UTC)
They changed their terms of service but no goverment made it illegal. Stop edit warring. -- GB fan 17:35, 13 October 2016 (UTC)

────────────────────────────────────────────────────────────────────────────────────────────────────You seem to be thinking that COPPA says that it is illegal for someone under the age of 13 to play Tetris. COPPA does not make anything illegal for the under 13. It makes things illegal for the websites, they are restricted in what information they can collect about under 13 year olds without their parents permission. The website can restrict access to those under 13 if they don't want to do the things they need to comply with the law for those under 13. None of this makes it illegal for someone under 13 to play the game. Also this only applies to those in the US. -- GB fan 18:12, 13 October 2016 (UTC)

Gonna throw some solidarity in for GB fan. "It is illegal for a 12-year-old to play Tetris" is a gross misunderstanding of the words "Children's Online Privacy Protection Act". (talk) 13:07, 30 November 2016 (UTC)

Changing of links[edit]

Along with the legal issue above the IP is also changing links.

Changing tetromino to tetrimino
Changing pentominoes to pentiminoes
Changing tetrominoes tp tetriminoes

None of these changes are helpful, some are even detrimental to the article as they create redlinks out of blue links. -- GB fan 17:31, 13 October 2016 (UTC)
