In Scrabble, players form interlocking words on the game board in a crossword fashion by using letter tiles of different value. Players compete for the highest score by using their letter tiles and the Premium Squares on the board. 

Each player has a rack of seven letter tiles, and their rack is continually replenished by tiles from a communal tile bag. Once all letters have been drawn from the tile bag and all possible plays have been made, the game ends. Whichever player has the highest score when the game ends is the winner!
