Disclosure: I made a small pledge of $10 which includes a PDF copy of the game and Print On Demand (POD) copy that I can order if I want to pay shipping.

How to play the Diception Dice games playlist (29 videos): https://www.youtube.com/watch?v=O7-Z3jy3tp4&list=PLZys0-FYPX-HECkIuvRKJCXlysmyKZONP
I think the decision to make videos showing how to play the games was a smart move. I read through the rules for many of the games and they are written well enough, but the videos provide walkthroughs in case you aren’t sure of how to play a game.
