Giant Jenga

Not sure why my entry for Giant Jenga was removed. Clever vandalism? I'm not that smart. This version, while heavy and bulky to store is has proven to be a hit at numerous parties. The idea should be shared!krioboy 05:01, 19 November 2006 (UTC)

Giant Jenga is commerically available, here are a couple of places that sell it:

Number of moves

In Theory, what is the highest number of moves possible in Jenga????

So the tallest tower would be 81 stories tall, with a single piece in the center of each story. That means that each of the lower 80 stories would have had three pieces in it at one point, and was then later reduced to one piece. So two moves per story = 160 moves? That's probably not an exact number, since you might run into some problems at the end when the top story is the only one with more than a single block, but that's got to be about right. --Dantheox 06:04, 10 December 2005 (UTC)

A more careful argument gives 152 moves, yielding a 78 story tower. Assume you're building a tower with one block per story (which you should, if you're maximizing total possible moves) and moves are made from the bottom up. Then a tower with n stories consisting of a single block has $81-n$ more blocks above these floors. So for $n<76$, there are $81-n\geq 6$ blocks on the top. Six blocks are required to make any moves (you need two complete stories). So you can get to $n=76$, leaving $81-76=5$ blocks on top. At this point, there are no more possible moves. By the reasoning in my previous post, $76*2=152$ moves were made to get to this point. Hopefully that's more of an answer than you were really looking for... =) --Dantheox 09:44, 10 December 2005 (UTC)

Man, if that's accurate, that's a great answer! And I think it's worthy of being in the main article. Can somebody with more statistical credibility than me please verify the math so we can find a place for it in the article? Joe 17:03, 11 December 2005 (UTC)

It's definitely interesting, but wouldn't this constitute "original research?" Unless there's a "theoretical Jenga" website out there somewhere. --Dantheox 23:35,

There are only 54 blocks in the traditional Jenga so here is my go.

Starting at the bottom.

2 Moves Out of moves because you have to leave 3

6 Moves 2/3 of 6 is 4 plus the 2 left over = 6 again

6 Moves 2/3 of 12 is 8 so 2 left over to start the next phase

12 Moves 2/3 of 15 is 10 so 2 left over to start the next phase

15 Moves 2/3 of 24 is 16 so 1 left over to start the next phase

24 Moves 2/3 of 36

36 Moves 2/3 of 54

101 Total Moves

Will anyone agree with me?????????????

Right, I don't know why I thought the tower started with 27 stories; It actually starts with 18. So my reasoning from before still applies... with $n$ defined as above, so long as $54-n\geq 6$, you can still make a move. So at the end, $n=49$, and the tower is 51 stories tall, and there would have been 102 total moves. Is there an off-by-one error in your calculations? --Dantheox 08:31, 13 December 2005 (UTC)

When you get to 101 moves, correct you are at deck 51 (stories tall). At this stage at the top you will have 2 blocks on top of 3 and can’t move any of them. This is where you lose the extra move. In other works your not left with 1, 1, 3. you will be left with 1, 3, 2. So my answer is still 101

OK, that's reasonable and I agree. Now all we need is a picture... --Dantheox 02:48, 14 December 2005 (UTC)

I Oppose a picture with 51 storeys as it will likely not be the result of a Jenga game. It would simply be a stack of 51 Jenga blocks. Pictures from a real game, following the rules, are more suitable for the article. Cafe Nervosa | talk 00:59, 22 December 2005 (UTC).

Nah, we don't need a picture. We've already got a good one. But I think a good narative about the maximum number of moves would be very appropriate. Joe 02:26, 8 January 2006 (UTC)

I counted, by hand, 98 moves until there are no more moves left (ended up with two blocks on top, so you were not allowed to take from the last complete layer). I may have counted wrong, so I will recount again a little later, but that's what I got. Of course, the rules don't state what happens when you quickly swipe out a block that his holding the whole tower, and the tower falls down one level but does not collapse. Like pulling a table cloth out from under dishes and no dishes fall off. While I think it is very unlikely that someone could actually pull of such a move, let alone get a game to last 98 moves, it is still theoretically possible, and as such the game of Jenga potentially has unlimited moves. JayKeaton 05:58, 15 April 2007 (UTC)

It most certainly is 98 moves. The tower ends up 51 high, the top two layers can not be moved as per the rules, which leaves 49 layers which have had two bricks moved from each, which adds up to a grand total of 98 moves. JayKeaton 15:17, 15 April 2007 (UTC)

Jenga is popular in the beer bars of Thailand

Yeah, right. I wonder how long a Jenga game can last when the players are drunk. Oh wait... maybe they use it as a test for drunkness. Definitely needs citation. 165.123.140.215 01:37, 8 January 2006 (UTC)

I, too, wonder about the validity of this claim. The Connect Four article also claims (undocumented) that the game is popular in the bars of Thailand and Argentina. Sounds dubious to me. Joe 02:23, 8 January 2006 (UTC)

I can confirm this - virtually every bar in Thailand had a Jenga set and a Connect Four set, and my favourite gave out a free drink if you beat the barman three times in a row. Can't cite it, alas, so maybe should be removed. Tyrhinis 10:35, 22 August 2006 (UTC)

yes I too have witnessed the Jenga sets in Thailands bars.. I'm going to have a look through some guide sites now, maybe it'll have a mention. If we can find something to cite it's too interesting not to include in the article.. Elmo 11:59, 29 June 2007 (UTC)

Jenga userbox

There's a Jenga userbox now, for those interested.

Chance

There is some degree of chance between skilled players, although slight. If two skilled players had a game they would reach a point where one of them will probably knock over the tower, after all the "good" moves have been taken and there are only "bad" moves left. So there is a set number of turns until there are only "bad" moves left. And seeing as it is only a two player game with one move per player, it stands to reason that your chances of being left with only "bad" moves is directly related to which of the two players sets up the game, or takes the first move and determines which moves will be played who and when 202.191.106.82 19:39, 11 April 2007 (UTC)

Not really because the players are manipulating what moves are still available. So in actuality, it isn't really chance but just setting the game up for later which could easily be added into a strategy. Megamanfanx7 15:15, 26 April 2007 (UTC)

Stabilisation permitted, placing of the block?

I have 2 queries regarding what is and is NOT allowed. 1) some people I know state that you are not allowed to stabilise the tower (with one hand) during your go (in order to make it less likely to collapse). Is that stated explicitly anywhere? Is there any reason it would not be- it leads to longer and better games? 2) are you allowed to place the piece your remove haphazarly anywhere on the top of the tower? Or must you place it more-or-less precisely square with the row below, or even only on one of the end slots?

I think these issues arise often during Jenga games (played by cometitive people) and therefore would be valuable insights in this article. Boldymumbles 20:32, 21 July 2007 (UTC)

Truth or Dare Jenga colors?

In the article, it is stated that Truth or Dare Jenga uses red and black blocks (in addition to the normal uncolored wooden ones), except in the picture, the colored blocks are red and green. Was/is there also an addition which included black blocks, or is the article incorrect?

History of Jenga

Hasbro's 'history of Jenga' (http://www.hasbro.com/default.cfm?page=ci_history_jenga) makes no mention of the previous incarnations of the same game by Whale Toys (as "Piza") and by Games Workshop (as "TOWERBLOX").

"JENGA celebrated its 15th anniversary in 2002," that page says, presumably relating to the "Hasbro Jenga," and placing its 'birth' in 1987.

I recall Games Workshop producing much the same game in 1982, except with 39 bricks (13 layers) instead of Jenga's 54. Here's a photo of a copy of the rules from GW's 'TOWER BLOX Pre-Production Set:' [1] (I took this photo myself, but don't know whether I can upload it to Wikipedia - I think not as GW will have copyright on the original document). Sadly there's no date on this document, but I'm fairly sure that it would have been 1981, or perhaps 1982.

When published by GW as 'TOWERBLOX,' this game didn't sell particularly well. Although I don't know for sure what happened next, I believe that the rights were sold on to Whale Toys, who produced it for a time as "PIZA," after which it then reappeared as the now well-known "Jenga." --Pendant 20:21, 5 November 2007 (UTC)
