Let me preface this thread by stating that I'm a DI skeptic. However, I'll credit myself as being the inventor of RDI. (As silly as the concept may be). It's basically the opposite of DI. DI: set the top face to a number you wish to land on and skilfully toss to try to get that number. RDI: set the top face to a number you don't want.... ...then throw like a spastic, hoping that the number on top doesn't show. Revolutionary! Don't you think?
