It's been over a year since Josh Wardle, a New York based software developer, first released Wordle to the public in October 2021, yet the game's extraordinary popularity shows few signs of abating.
The rules of Wordle are very simple meaning almost anybody can play, even if they have no prior experience with word games. Each day the player is tasked with working out a new five letter word, in six attempts or less.
After each guess the letters change color, indicating how accurate it was. If a letter goes green it is both in the word, and in the position you put it. Yellow means the letter features, but in a different place, whilst gray tells you it's not included at all.
Wardle, originally from the U.K., first developed Wordle during coronavirus lockdown "for me and my partner to enjoy."
After becoming publicly available Wordle became a viral sensation, with many players posting their scores on social media each day. In January Wardle sold the game to the New York Times, for an undisclosed seven figure fee, though it remains free to play.
Since it's release Wordle has helped inspire a number of other online puzzles, including Nerdle for math enthusiasts and Worldle for geography fans.
