"Figure it out" is a common phrase, but it doesn't have a specific "word of honor" associated with it.
To help me understand your request, could you tell me:
* What is the specific context of "figure it out"? Is it a game, a challenge, a personal goal?
* What do you mean by "word of honor"? Do you mean a code word, a motto, a specific phrase used to signal completion?
Once I have more information, I can help you figure out what the "word of honor" might be.
