Read about Wordle and answer the question.⬇️ Josh Wardle developed a game to play with his partner - and now more than 2m others have joined in making it a worldwide sensation. It is a simple online word puzzle, which has had a incredible rise since its launch last autumn, from go daily players in November to 300,000 at the beginning of January, to 2 million last weekend. But, for its creator, the game's rapid success has resulted in as much anxiety as excitement. The game has become an unexpected grassroots hit for Josh Wardle, who developed it for his puzzle-loving partner. The pair played it for fun on their sofa, and other users slowly began to join them. Every day, there is a new word to guess, and players get just six chances to identify it. Wordle's popularity is thought to be partly because, in an era of apps aggressively competing for your attention and time, the game was built to be played once a day, and without functions designed to promote its growth such as push notifications and email sign ups.
