Do you want to double the Wordle++ challenge? Try Dordle, a double variant of Wordle++. Joining Dordle, you will solve not only one word but 2 words at a time with up to 7 attempts.
Start by entering any word and it will appear on both grids. That forces you to guess both words at once. Clues are also provided through the same colored tiles as Wordle++, so it is better to choose the grid with more clues to solve first. However, you need to make sure that once a word is found, there will still be a guess to solve the other.
