Tens of thousands play club and tournament "Scrabble" worldwide. All tournament (and most club) games are played with a game clock and a set time control. Although casual games are often played with unlimited time, this is problematic in competitive play among players for whom the number of evident legal plays is immense. Almost all tournament games involve only two players; typically, each has 25 minutes in which to make all of their plays. For each minute by which a player oversteps the time control, a penalty of 10 points is assessed. The number of minutes is rounded up, so, for example, if a player oversteps time control by two minutes and five seconds, the penalty is 30 points. There are also games that count the time by fractions of a minute. Also, most players use molded plastic tiles, not engraved like the original wooden tiles, eliminating the potential for a cheating player to "braille" (feel for particular tiles, especially blanks, in the bag).
