I don't like giving away free stuff. People and companies only give away free stuff if they think that doing so will benefit them in some ways. Generally, the purpose for giveaways is to promote a product. That is my motivation for offering the free PDF download of the sample puzzles from my puzzle book, Eye-Q, Visual Puzzles for Reason-able People.
Unfortunately, from past experience, I learned that this does not work for me. It does not get me any publicity. It does not get me any new backers. It does not pre-sell any of my product. That is why I don't like giving away my hard work for free.
But since this is my last Kickstarter campaign, I'll do it. (My biggest fear in giving these samples and sharing my ideas, in general, is of internet idea scavengers. I have amazing ideas and I do not want them stolen. I know of one successful Kickstarter project that is based on the ideas I presented in my Labyrinthos campaign. (More on that later.) I have no doubt that other thefts will soon follow. (No, I do not think that I am the only person in the world with original ideas. But the reality is that people with original ideas are rare. Most creative types steal other's ideas, the internet is a great tool for that, change them a bit, and call them their own.))
You can download the sample booklet from www.konokopia.com. If you like the puzzles, you can pre-order the book from Kickstarter. But if you have interest in the book, back it now because I am thinking of canceling the campaign Saturday if the book does not garner significantly more support.
