Okay, I made this puzzle months ago. I remember the rules, but not the answer.
Each row is a word and each box holds one letter. Boxes of the same color are the same letter as well; as there are only 7 colors, the whole puzzle uses only 7 letters. The goal is just figuring out what all 9 words are.
For those with difficulty with colors, below is a text copy of the puzzle; each number matches one of the colors:
123
4352
34265
627534
6215365
52364211
231526726
5211244352
25267347211
