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 !

Siberia has population density of only three persons per square kilometer. The oblasts with the highest population densities are Chelyabinsk Oblast and Kemerovo Oblast, with 41 and 30 persons per square km, respectively. Koryak Okrug has population density of less than 0.1 per square kilometer.
About 70% of Siberia's people live in cities. Novosibirsk is the largest city in Siberia, with a population of about 1.5 million, followed by Yekaterinburg (1.3 million, Urals), Omsk (1.1 million), Chelyabinsk (1.07 million, in the Urals), Krasnoyarsk (0.91 million), Barnaul (0.60 million), Irkutsk (0.59 million), Kemerovo (0.52 million), Tyumen (0.51 million), Tomsk (0.48 million), Nizhny Tagil (0.39 million, Urals), Kurgan (0.36 million), Ulan Ude (0.36 million), Chita (0.32 million).
The above count, however, by including the entire Urals Federal District, includes areas not usually considered part of Siberia, e.g. the cities Yekaterinburg and Chelyabinsk and Nizhny Tagil listed above.
Most non-Slavic groups are Turkic. Smaller linguistic groups are Mongols (ca. 600,000 speakers) Uralic (Samoyedic, Ugric; roughly 100,000 speakers), Manchu-Tungus (ca. 40,000 speakers), Chukotko-Kamchatkan (ca. 25,000 speakers), Eskimo–Aleut (some 2,000 speakers), the Yukaghir languages (highly endangered), and languages isolates Ket (but see below) and Nivkh.
Mongolian, Turkic and Manchu-Tungus languages are sometimes taken together under the term Altaic. At one time Uralic and Altaic were believed to form the Ural–Altaic group, though this theory has now been largely discarded. The proposed Uralo-Siberian family combines the Uralic family with the Yukaghir languages, Chukotko-Kamchatkan, and Eskimo–Aleut. These are more umbrella terms than accepted linguistic relationships. Ket has recently been linked with the Na-Dene languages into a Dené–Yeniseian group; while not universally accepted a broad consensus in favor of the proposal has emerged.
