This book is an interactive set of solo rules that guide your improvisation and acts as a GM for your adventures. In place of the common lists of words, this booklet uses visual icons to inspire you. Unleash your adventurous spirit and explore stars without number. Solo is a perfect way to learn a new game, test your first adventures and going beyond just making characters when you are first getting to know the rules. Stars Without Number [SWN] is one of the most popular OSR role-playing games ever released. While it is very similar to a lot of dungeons & dragons derived games it diverges when it comes to the skill system. Outside of combat, SWN is mostly driven by 2d6 rather than the ever-present d20 so common in other OSR games. If you have never solo played an RPG before I will ease you into that as it is a different experience from any other form of role-playing. All role-playing is improvisation. If you are a GM and your players go off course, the improv tool in this book will help you create exciting adventures on the fly. All the rules in this book are at the front. You then get three useful record-keeping pages which you may print multiple copies of for your own use. Finally, there are ten pages of ‘game icons’. These you may also print off if you prefer to have them on paper.
