Scrabble Showdown set of 16 letter tiles are placed on the board. A randomizer then causes tiles to light up. Each team is allowed to stop the randomizer; a team starts the final round with the regulation value of the tiles that they stop the randomizer on; the number of tiles that the randomizer lights up is the number of "Bonus Scrabble Tiles" that the team had earned from the three previous rounds. This becomes their "head start" score before playing "Scrabble Lightning". The game is played on a regulation Scrabble board with only the double and triple-word score spaces (the double

The "endgame" phase takes over as soon as there are no tiles left in the bag. In two-player games, this means that the players can now deduce from the initial letter distribution the exact tiles on each other's racks.
