ThunderCloud Posted December 17, 2017 Report Share Posted December 17, 2017 (edited) I did not see this puzzle mentioned in the forum before: Twenty Questions by Don Woods. I was able to solve it by computer (I verified my answer with the author), but even that wasn't easy! I'd love to hear of others' experiences with it. ^.^ Edited December 17, 2017 by ThunderCloud Quote Link to comment Share on other sites More sharing options...
