Sorry to mess up your forum I hope you will forgive me being a beginner.
If I understand you correctly only the winner of the current challenge is entitled to make the next move.
And what happens if the challenge is not accepted and nobody knows what the submitted item is?
Is there a time limit within which the "sbmitter" has to show his cards and solve the riddle (if nobody guesses of course)?
I hope I made myself clear
