I'm hoping somewhere in the Jenga rule book that it negates the use of anything "but" the complete use of fingers to move the blocks. Otherwise, everyone is going to show up at the World Jenga Championships with these guns, and the entire competitive industry surrounding Jenga, will collapse.
I thought it was a great hack, too. I suppose we should stop passing out opinions here since they get down-modded. Folks, you can just not mod posts that offer no inheriant value to you.
Do you want someone down-modding your posts simply because you are expressing how you feel in the moment and had nothing else valuable to say? I looked specifically at the comments in this post because I wanted to up-mod someone who said "great hack" because I felt the same.
