What is the significance of the tile score in the game of Scrabble?

The tile score in Scrabble is significant because it determines the points a player earns for each letter they use to form Words. Higher scoring tiles like Q and Z can help players earn more points, while lower scoring tiles like E and A are more common but offer fewer points. Strategically using high scoring tiles can lead to higher scores and increase a player's chances of winning the game.
