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 !

Daniel Nathans (October 30, 1928 – November 16, 1999) was an American microbiologist.
He was born in Wilmington, Delaware, the last of nine children born to Russian Jewish immigrant parents. During the Great Depression his father lost his small business and was unemployed for a long period of time. Nathans went to public schools and then to the University of Delaware, where he studied chemistry, philosophy, and literature. He received his M.D. degree from Washington University in St. Louis, Missouri in 1954. Nathans served as President of Johns Hopkins University in Baltimore, Maryland from 1995 to 1996.
Along with Werner Arber and Hamilton Smith, Nathans received the Nobel Prize in Physiology or Medicine in 1978 for the discovery of restriction enzymes. He was also awarded with National Medal of Science in 1993.
In 1999, Johns Hopkins University School of Medicine announced the creation of the McKusick-Nathans Institute of Genetic Medicine that was named in his honor posthumously along with Victor McKusick . In 2005, the School of Medicine named one of its four colleges after Dr. Nathans.
