Wordle 640 Answer Today, March 21: The Wordle challenge today is tough, believe it or not! The word of the day is a fairly common word but one of the many that sound different that how they are spelt. The word contains a good mix of vowels and consonants, with no absolutely rare letter. The combination of letters will be easy to guess if you crack the last two letters and their positions first. The problem of multiple options exists but should not prove to be much of a threat if you get the vowels right. Need more help to solve Wordle 640? Keep reading.


How To Play Wordle And What Its Rules Are


Josh Wardle, a US-based software engineer, created Wordle in 2021. In January 2022, it was acquired by The New York Times.


Wordle is a popular, free-to-play guessing game that remains unchanged following the takeover. A new challenge is released globally every day, with some countries seeing the five-letter word before others. 


The rules of the game are simple: players have six chances to guess the randomly generated word of the day. Squares representing letters turn green, yellow, or grey depending on the status of the letters entered, with the colours indicating if the player is on the right track or not. A green box means the letter is in the correct position, a yellow box means the word contains the letter but it is placed incorrectly, and a grey box means the letter is incorrect.
