Letter values began with counting
Scrabble’s numbers were designed to make rare letters more costly to play than common ones. In developing the game, inventor Alfred Mosher Butts studied how often letters appeared in English, using newspaper text as a practical sample. Letters that turn up in many words—such as E and A—could be worth little; letters that are harder to find a place for, such as Q and Z, needed higher scores.
That logic explains the broad pattern, but the values are not a simple ranking where each letter’s score directly equals its rarity. Butts had to turn language frequencies into a playable scoring system: a rare letter should be rewarding when used, yet not so valuable that one lucky draw decided the game.
The score and the tile supply work together
A letter’s point value is only half the design. The bag also contains different numbers of each letter. Common letters appear in greater supply, giving players more chances to build ordinary words; scarce, high-value letters are harder to draw and can be awkward to place. The blank tile, which can stand for any letter but scores zero, offers flexibility instead of points.
The result is a built-in tradeoff. A player holding a Q may have a chance to score big, but must find a legal word and a useful place on the board. Meanwhile, familiar letters are easier to combine, though they usually pay less on their own. The values turn the unevenness of English spelling into a game of risk, timing, and placement.
