What is scrab?

Scrabble is a popular word game that involves players forming words on a board using letter tiles. Each letter is assigned a specific point value, with more common letters like "E" worth only one point, and less common letters like "Z" worth ten points. Players take turns placing one or more tiles on the board to create words that intersect with other words already on the board. Players can also challenge the validity of any word played by their opponents. The game ends when all tiles have been used and one player has no remaining tiles in their rack, or when a player decides to end the game prematurely. Scrabble is available in many different languages and is enjoyed by people of all ages around the world.
