Question.

I have a new puzzle, it's 1000s of pieces. I want to put it together and see the perfectness I've created. I'm patient so I don't mind if it takes a while. However, I accidentally drop the box on the floor before I start. 

Shoot. 

I scramble on my knees to ensure I don't miss anything, I want it to be complete. It takes a lot of hard work and time for perfection. 

I get off my knees and start putting it together, turning pieces to ensure they fit together correctly. Sometimes it takes a few attempts for them to fit. 

I'm so close, I'm almost there, when I notice- uh oh ... I'm missing one final piece. It is a very valuable piece, one the puzzle cannot be complete without. I go on my knees again, and look so hard for the missing piece, but it cannot be found. 

Question.

Is it still complete without a fundamental piece? Or am I going to have an issue with the puzzle not being complete.
