This game is tough with a lot of uncertainty. I would prefer if this 3D Numbered Ordering game had a few more inferences that could be made before you begin the questions. This game requires a lot of plug and chug. Set up the game board, notate the constraints, look for inferences (which there really aren't many) and get going with the questions!
I've attached the setup, if you'd like to take a look.

Also, you mentioned something about having more characters than spaces. That is a twist on this game. There's an element of selection going on. Choose six, distribute to either the am or the pm row, and order one through three. We've seen regular Numbered Ordering Games that do something similar - of eight, choose six, and order them. It's not uncommon for them to give you either more characters than spaces or more spaces than characters.
Let me know if you have a specific question from this game, you'd like to take a look at!
