Lettris
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
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 !

Merriam Webster
UU (ū), the twenty-first letter of the English alphabet, is a cursive form of the letter V, with which it was formerly used interchangeably, both letters being then used both as vowels and consonants. U and V are now, however, differentiated, U being used only as a vowel or semivowel, and V only as a consonant. The true primary vowel sound of U, in Anglo-Saxon, was the sound which it still retains in most of the languages of Europe, that of long oo, as in tool, and short oo, as in wood, answering to the French ou in tour. Etymologically U is most closely related to o, y (vowel), w, and v; as in two, duet, dyad, twice; top, tuft; sop, sup; auspice, aviary. See V, also O and Y.
See Guide to Pronunciation, §§ 130-144.

U (named u /ˈjuː/, plural ues)[1][2] is the twenty-first letter in the ISO basic Latin alphabet and a vowel in the English alphabet. It is the chemical symbol for uranium.
Contents |
History
The letter U ultimately comes from the Semitic letter Waw by way of the letter Y. See the letter Y for details.
During the late Middle Ages, two forms of "v" developed, which were both used for its ancestor u and modern v. The pointed form "v" was written at the beginning of a word, while a rounded form "u" was used in the middle or end, regardless of sound. So whereas valor and excuse appeared as in modern printing, "have" and "upon" were printed haue and vpon. The first distinction between the letters "u" and "v" is recorded in a Gothic alphabet from 1386, where "v" preceded "u". By the mid-16th century, the "v" form was used to represent the consonant and "u" the vowel sound, giving us the modern letter "u". Capital "U" was not accepted as a distinct letter until many years later.[3]
Usage
In most languages that use the Latin alphabet, ⟨U⟩ represents the close back rounded vowel /u/. In English it commonly represents /ʌ/ or /ʊ/ ("short U") as in duck, or /ju(ː)/ ("long U") as in mule. Additionally, the letter U is used in text messaging and internet and other written slang to denote you, by virtue of both being pronounced [juː]. In French the letter represents the close front rounded vowel; /u/ is represented by ⟨ou⟩.
