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 !

It was discovered by Auguste Charlois on May 3, 1888 in Nice. (277) Elvira is possibly named for a character in Alphonse de Lamartine’s Méditations poétiques (1820) and Harmonies poétiques et religieuses (1830).
A group of astronomers, including Lucy D’Escoffier Crespo da Silva and Richard P. Binzel, used observations made between 1998 through 2000 to determine the spin-vector alignment of the Koronis family of asteroids, including 277 Elvira. The collaborative work resulted in the creation of 61 new individual rotation lightcurves to augment previous published observations.
