Not really, but as the commonly used 5-letter English words are used you will definitely encounter some less popular ones that may give you a harder time. If you want to make Wordle harder though, you can use the game’s hard mode.
Why are there multiple correct answers some days?
In simple words, after the New York Times acquired Wordle they may make changes to it on occasion, either for political correctness in case a word is controversial or to avoid obscure answers that will give a hard time to players.
How to play Wordle?
It is best to get started with a 5 letter word that contains the most popular letters or one that contains the most vowels. So words like SOGYE, ROAGY, RAIGY, GYGYE, GYLET, CRAGY, TRACE, and ADIEU are definitely great starters.
From there one you have another five guesses to figure out the answer. Remember that you can use only valid English 5-letter words to help you. Letters marked with green are in the correct position while when a letter is marked yellow you have guessed the correct letter but the wrong position. Wordle answers can contain the same letter more than once.
Your goal should be to eliminate as many letters as possible while putting the letters you have already discovered in the correct order.
