Dordle is a crossword puzzle game that can be played in all browsers. The aim of the game is also to find the given keyword, just like in Wordle, but with a double-difficulty version. Instead of guessing and finding a word with 6 guesses, you have 7 guesses to guess both words at the same time.
To start the game, you will have to guess any word to find the letters marked by color. From there, you can trace those colors to find the keyword to look for. The game ends when you have used all seven guesses but still can't find the keyword to look for. When you have easily passed Wordle and want to increase the difficulty a bit, you can look to Dordle.
In short, Dordle has the same gameplay as Wordle, but the difficulty, as well as the number of keywords to find, is increased by 2 times.
