Wikibooks (previously called Wikimedia Free Textbook Project and Wikimedia-Textbooks) is a wiki hosted by the Wikimedia Foundation for the creation of free content textbooks and annotated texts that anyone can edit.
In April 2010, Alexa ranked wikibooks.org as the 2,462nd most popular web site in the world. Compete.com estimates that Wikibooks had 576,838 unique visitors, and Quantcast estimates 646,500 unique visitors from the United States in that month.
Wikibooks was launched on July 10, 2003, in response to a request made by Wikipedia contributor Karl Wick for a project to host and build free textbooks on subjects such as organic chemistry and physics. Two major sub-projects, Wikijunior and Wikiversity, were created within Wikibooks before its official policy was later changed so that future incubator type projects are started according to the Wikimedia Foundation's new project policy. In August 2006, Wikiversity became an independent Wikimedia Foundation project.
Wikijunior is a subproject of Wikibooks that specializes in books for children. The project consists of both a magazine and a website, and is currently being developed in English, Danish, Finnish, French, German, Italian, Japanese, Spanish and Arabic. It is funded by a grant from the Beck Foundation.
While some books are original, others began as text copied over from other sources of free content textbooks found on the Internet. All of the site's content is released under a Creative Commons Attribution-Share Alike license (or a compatible license). This means that, as with its sister project, Wikipedia, contributions remain copyrighted to their creators, while the licensing ensures that it can be freely distributed and reused subject to certain conditions.
Wikibooks differs from Wikisource in that Wikisource collects exact copies and original translations of existing free content works, such as the original text of Shakespearean plays, while Wikibooks is dedicated either to original works or to significantly altered versions of existing works.
The project is working towards completion of textbooks on numerous subjects, which founders hope will be followed by mainstream adoption and use of textbooks developed and housed there.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
