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 !

Stephen Euin Cobb (born February 3, 1955) is a U.S. author, magazine writer, interviewer and host of the award-winning podcast The Future and You. A contributing editor for Space and Time Magazine, and a former contributing editor for Robot Magazine; he writes regularly for H+ Magazine, Grim Couture Magazine, Digit Magazine and Port Iris magazine; and for three years was a columnist and contributing editor for Jim Baen's Universe Magazine. Cobb is also a game designer, artist, essayist, futurist, transhumanist, and is on the Advisory Board of the Lifeboat Foundation.
Most of Cobb's articles and columns in magazines center on technology and/or science. His essay-style articles also center on technology and science but often speculate about how the trends visible today will alter the future. He has also done celebrity interviews.
Articles about the future include: Fifteen Ways Cheap Solar Cells are going to Change the World, What I've Learned Interviewing Futurists and Your Medical Care in the Coming Three Decades.
Science speculation articles include: The Perpetual Electron and The Universal Diagram (published in the February 2007 episode of Jim Baen's Universe Magazine, in which he proposed a method of charting, in three dimensions, all the celestial objects in the universe to make their relationships more obvious. This can be considered vaguely analogous to the two dimensional Hertzsprung-Russell diagram of stars.)
Transhumanist articles include: Five Famous Authors do Public Appearances in Second Life, Earth's Next Schism, The Coming Popularity and Power of Luddism and Transhumanism's Universal Success is Unavoidable
(These examples are all from Jim Baen's Universe Magazine. None have been included from Robot Magazine, Space and Time Magazine, Grim Couture Magazine, Port Iris Magazine, H+ Magazine or Digit Magazine.)
Bones Burnt Black (2004) is his most widely read novel. It was serialized as an audio book in his podcast during the show's first two years (from December 2005 to November 2007). It is an action/adventure, murder/mystery involving a series of murders aboard a large passenger spacecraft which has been sabotaged by the killer.
Skinbrain (Cerebrodermus Fantastica) (2011) is his most futuristic book. It contains the most deviations from our current technology level.
He also contributed a short story called The Errand Boy to the anthology Writers for Relief. (All the profits of this anthology are being donated to the victims of hurricanes Katrina and Rita.)
As a novelist, he specializes in hard science fiction (fiction with a high degree of scientific accuracy). All of his novels occur within the same fictional universe which has been nicknamed "Naked Space" in honor of a fictional cosmological theory put forth by a character in one of his novels. (His short story The Errand Boy is a timetravel story, and so does not seem to fit within his Naked Space universe.)
Since 2005, Cobb has been the host of The Future and You, a weekly talk-show style podcast; for which he has interviewed over 300 authors, futurists, scientists and celebrities  as to the trends they see changing the world, and our lives, in both the near and distant future.
He is a member of the Beaver Creek Tribe of Native Americans in South Carolina. His mother, Jewel Caroline Cobb (maiden name: Hoover), served one term as a member of the Tribal Counsel. (His mother's sister Emaline Barr has also served one term.) For the tribe to achieve state recognition, complete genealogical records of several tribal members had to be produced and certified as accurate; his mother was one of this core group. Records authenticate that her ancestry is no less than 1/4 Native American (uncertified records indicate that she is probably 1/2 Native American). Because of this, Stephen Euin Cobb is somewhere between 1/8 and 1/4 Native American.
His hobbies include: astronomy (he has a 10.1 inch Dobsonian style Newtonian telescope), handwriting analysis, and drawing in pencil, charcoal and pastels. He also collects fossils, artwork and autographed books.
Within that virtual world he helps organize and promote events dealing with science fact, fiction and the future. Examples include his arranging David Brin's personal appearance for the Yuri's Night 2008 celebrations within Second Life which took place on April 12, 2008; and his arranging the personal appearance made by Robert J. Sawyer for an open forum lecture in the Grand Hall of the Central Nexus Building, followed immediately by a smaller discussion with the Extropia Book Club concerning Robert J. Sawyer's latest novel Rollback which was held on April 6, 2008; and his arranging the personal appearances made by Catherine Asaro on August 9, 2008, and by Kim Stanley Robinson on January 17, 2009.
He is also a noted photographer and photojournalist, and maintains office space on the eighth floor of the Central Nexus Building in Extropia Core.
He has invented a number of games, the most famous being Death Stacks, for which there is an annual tournament in Charlotte, North Carolina. The Death Stacks tournament has been added to the IAGO World Tour  by the International Abstract Games Organization.
He is the inventor of the Ignorance Index, an empirical rating system for talk shows on radio and television.
He is a founding member of The Order of Cosmic Engineers.
