I think the problem is the game setup pre-supposes a slow but steady march towards sufficient knowledge to find the answer. The problem is lack of participation shuts down the information transfer. Furthermore, there is no incentive to tell the truth, which shuts down information transfer entirely. If only one player lied, then maybe by iteration one could come up with the answer, but if 2 lied then finding the correct answer by brute force is not plausible. More than that, and well, no answer is forthcoming.
From a game theory point of view, there is no reason to tell the truth. Benefits can be had from lying, and telling the truth only helps your competitors. Plus, no one could even prove that you were lying.
Some mechanism for increasing knowledge as time passes is required to keep the game moving.

Because, you know, I don’t think a simple bump would do anything in this game.
