The objective of Scrabble is to score the highest number of points by forming words on the board using letter tiles.
Each player draws seven tiles. The first word must be placed on the center square of the board.
Words must read left to right or top to bottom and must connect to existing words.
Points are calculated based on letter values and bonus squares like Double Letter or Triple Word.
Special board squares multiply letter or word scores when tiles are placed on them.
Players may challenge words they believe are invalid according to the dictionary in use.
The game ends when tiles run out or no player can make a valid move.
Different tournaments use different dictionaries like CSW or TWL.
