Absurdle is for those who want a more challenging experience and access to an infinite number of puzzles. Absurd seems to select a single secret word, but in reality it takes into account every possible secret word that fits your current set of guesses.
You can submit as many or as few guesses as you like, unlike Wordle. In any case, you should try to limit your guesses to no more than six words to speed up the process. Starting with over 2,000 words, Absurdle's internal list of words will become progressively smaller depending on the word you enter.
The point of the game is to use your knowledge of a particular word to narrow the available options until you reach the one you want. In the beginning, you have nothing but a clean slate. You can expect the first few words you type to be completely grayed out as the system stubbornly resists your input. As you progress toward the word you've pinned, Absurd creates a word pool of possible solutions, which is narrowed down.
Using two words at the beginning that share no similar letters is the quickest way to narrow down the list of possible words. This gets rid of any two-word combinations that use those grey letters.
