Trifold games are designed to be:
Concise – a trifold pamphlet of six pages must contain everything you need to play
Portable – you need only the pamphlet, friends, scrap paper, pencils and possibly some dice (preferrably only D6s that can be raided from other games)
Low- or no prep – easy to pick up and play, low stakes, play to find out what happens
Free – free to download, print, share and use under the Creative Commons license CC-BY-SA-NC 3.0
