# Today's 'Wordle' Answer #306: April 21 Hints and Clues to Solve Word Puzzle

Players may need some clues to help them hit upon the correct Wordle today, since the puzzle is proving particularly tricky for some.

The brainteaser, which involves players from around the world, simply asks users to solve the puzzle by guessing a mystery five-letter word — in six tries or fewer.

The game refreshes each day, with a new word that needs to be worked out from scratch. Wordle tries to help users stumble across the correct word by using a color-coded system; each correct letter turns green, or yellow if it's in the word but is currently in the wrong place, or grey when it's incorrect.

But for players who are worried about breaking a winning streak, Newsweek has created some helpful hints to help nudge them in the right direction. Failing that, the answer is provided at the end of this article.

## The Origins of 'Wordle'

Game inventor Josh Wardle created the game to play with his partner Palak Shah. He had first started working on it back in 2013, and returned to the game during the pandemic and perfected it.

Wardle made the game public in October 2021 and it quickly became a global phenomenon, thanks to its fun premise as a daily brain exercise. It gained more than 45 million users after starting out with just 90 active players.

The software engineer sold his game to The New York Times for an undisclosed seven-figure sum in January 2022 and the puzzle moved over to the publication in February. The word game has become so popular that it has inspired a number of other daily games like the music-based Heardle, and the math-based Nerdle.
