Moving from five letters to six does more than add one tile. English has a large number of six-letter words built around suffixes like -tion, -ness, -ment, and -ing, so a single confirmed ending can unlock or completely redirect your search. At the same time, those common patterns create traps: two yellow letters that look like the start of -ation might belong to an entirely different arrangement. The extra column gives you more confirmed information per guess when things go well, but it also means a poorly chosen opener leaves a wider open field than you would face in the five-letter version.
Players who already have a five-letter routine often notice that their second guess needs to work harder here. The vocabulary is richer, so a single information-gathering round rarely narrows the answer to a handful of candidates. Treating the first two guesses as a coordinated pair, each covering letters the other does not, tends to compress the remaining possibilities far more efficiently than trying to build on a single strong opener.
