Reverse Wordle with 4-letter words. Fewer letters per row, but also fewer words to choose from.
The bottom row is a 4-letter answer. Fill in the rows above it with real 4-letter words so that each one gives exactly the colors shown.
Letters found in a row must be used again below it, and gray letters can't come back. In Unlimited you can choose 3, 4 or 6 rows.
