How to play Quordle game?

The four 5x9 grids on the board that represent the four secret words you have to uncover are where quordle is set up.
You have nine attempts to guess four words. (One word with the same number of letters appears on each board.)
You start by entering any five-letter word at random. All four grids will simultaneously have your entered word filled in.
Each guess causes the letters in each of the four fields to change color.
A green box indicates that the letter is accurate and positioned correctly.
Yellow box: the letter needs to be in a different location even though it is in the hidden word.
A grey box: the word doesn't contain the letter.

Try to analyze the color hints to eliminate the wrong letters and find the correct words.
