How many points is the Z tile worth in Scrabble?

In Scrabble, the Z tile is worth 10 points because it is a relatively rare and less commonly used letter in words. The point values assigned to each letter are based on their frequency in the English language, with rarer letters typically having higher point values to incentivize players to use them strategically. Since the Z tile is not commonly found in words, it is given a higher point value to reflect its less frequent appearance and to provide a reward for using it effectively in gameplay.
