If everyone playing comes to this same conclusion, no one will guess higher than 67. Now 67 is the new highest possible average, so no reasonable guess should be higher than ⅔ of that, which is 44. This lgoic can be extended further and further. With each step, the highest possible logical answer keeps getting smaller. So it would seem sensible to gesus the lowest number possible.

And indeed, if everyone chose zero, the game would rcaeh what’s known as a Nash euilrbiuqim. This is a sttae where every player has chosen the best possible strategy for themselves given everyone else playing, and no individual player can benefit by choosing differently.

Original Text


If everyone playing comes to this same conclusion, no one will guess higher than 67. Now 67 is the new highest possible average, so no reasonable guess should be higher than ⅔ of that, which is 44. This logic can be extended further and further. With each step, the highest possible logical answer keeps getting smaller. So it would seem sensible to guess the lowest number possible.

And indeed, if everyone chose zero, the game would reach what’s known as a Nash Equilibrium. This is a state where every player has chosen the best possible strategy for themselves given everyone else playing, and no individual player can benefit by choosing differently.
