Tile tracking or 'consonant-heavy', how many S's or blanks are unseen, if an opponent is likely to have a bingo on their rack, or which tiles to play or conserve. For example, if Alice has the option of playing J(I)NN or J(I)LL, and four N's and zero L's remain unseen, then assuming both plays are otherwise equal (in terms of score, openings for the opponent), J(I)NN is likely the better play. Letter frequency lists for both Scrabble and Words with Friends are easily accessible (some versions of Scrabble have the tile distribution directly on the board) and, unlike word lists, using them
Scrabble letter distributions distributions lack "K", "Q", "W" and "Y", since they are only used in foreign words. You can still use a blank to play these letters. Arguably "X" does not exist in Romanian either, but it is included as it is used for borrowed words. Russian-language Scrabble sets, which use Cyrillic letters, contain 104 tiles using this distribution: The former Soviet distribution had 126 tiles and was as follows: Another Russian version, called Эрудит (Erudit), has 131 tiles: This distribution has no Ë tile. In "Erudit", only nominative singular and "pluralia tantum" nouns are allowed. Scottish Gaelic-language sets originally were planned
