Please do NOT post spoilers. Do NOT post hints. Do NOT tell us what actual letters you got.

I finally did it: got it in one today. I got it because someone posted two letters he got in the wrong place, and the last letter which was in the correct place. I thought of a word with those two letters in different places, and the end letter, and thought "well, maybe", typed it in, and that was it.
Frankly, it was cool to get it right that fast, but it wasn't fun.
