The Online version of the Lowest Unique Number Ballot is here. You can try it by clicking this link – Online Lowest Unique Number Ballot
The rules are simple. Enter your email address and a number. Choose a group number that you would like to enter against. For example, you might want to go against 9 others in a group of 10 people. Choose a group size of 10.
Or you might want to try a larger group – choose 20 or 50.
Once the right number of people have voted, you will receive an email with the results and other interesting stats about the game.
You can vote as many times as you like but only once for the same group.
This idea came from the amazing Jo Morgan (aka. @mathsjem who writes the exceptionally useful blog Resourceaholic). Jo ran a ballot like this at a mathsconf some years ago.
We offered this as a weekly challenge and felt that some people might like to experiment with it further.
