Question:  What games tiles tiles must form words which, in crossword fashion, read left to right in rows or downwards in columns, and be defined in  a standard dictionary or lexicon, Scrabble or Take It Easy?
Context: Take It Easy is an abstract strategy board game created by Peter Burley.  It can be characterized as a spatial bingo-like game, and has been published by Ravensburger and subsequently by several other publishers since 1983.  Each player gets a board with places for 19 hexagon tiles to place in a hexagon shape.  Additionally, players get identical sets of tiles which have different types of colored/numbered lines crossing in three directions.  One player draws a tile randomly and then tells the others which he drew.  Each player then puts their matching tile on their board in any available spot.  This is repeated until the board is filled.  The object is to complete same colored/numbered lines across your board, for which points are scored according to the numbers on those lines.  The maximum score possible is 307. Scrabble is a word game in which two to four players score points by placing tiles bearing a single letter onto a board divided into a 15×15 grid of squares.

Medieval letter tiles are one-letter ceramic tiles that were employed in monasteries and churches of the late Middle Ages for the creation of Christian inscriptions on floors and walls.  They were created by pressing stamps bearing a reverse image into soft clay, which was then baked hard, and they were used to form words by assembling single-letter tiles in the desired order. Tile tracking is a technique most commonly associated with the game of Scrabble and similar word games.  It refers to the practice of keeping track of letters played on the game board, typically by crossing letters off a score sheet or tracking grid as the tiles are played.  Tracking tiles can be an important aid to strategy, especially during the endgame when there are no tiles left to draw, where careful tracking allows each player to deduce the remaining unseen letters on the opponent's final rack.  The marking off of each letter from a pre-printed tracking grid as the tiles are played is a standard feature of tournament play.
