As you play a game against an opponent, you’ll notice that some tiles have the letters “DL”, “TL”, “DW” y “TW” on them. This means: “Double Letter”, “Triple Letter”, “Double Word” and “Triple Word”, respectively. In other words, if you form a word with a tile that contains any of these letters, you’ll either multiply the individual value of the tile (DL & TL) or the full value of the word (DW & TW).
