Scene Unfolding Machine for Solo RPG
A downloadable game
The Scene Unfolding Machine (SUM) is a supplement of random tables to get ideas during your roleplaying games. It has been created for solo or GM-less play in mind, but you can use it as a way to improvise content as you play.
Its focus lies on NPC interaction and personalities. It gives you innumerable combinations of character behavior, personalities, first impression and even dialogue prompts. On top of that, it includes elements of surprise, reactions, and ways to open up new scenes.
SUM is a must-have resource to expand your Solo RPG setup by giving your Scenes and NPCs a lot more of depth, particularly when you run out of ideas! It expands any solo system, working best with my other supplements: PUM and GUM.
Now available! PUM Companion - The app to play PUM-SUM-GUM seamlessly

Hi - I finally purchased SUM (along with PUM) and so far I'm really impressed :)
I do have one question however, how can I acess the tables (action, adjective, etc) from V.6? The latest version (7) does not seem to include them.
Hey xel! Thanks. Made a hard call and to avoid repetition, those oracle tables are in the GUM file. You can also find them in the free versions of SUM and GUM.
Thanks a lot for the reply as well as your work on the GMEs!
Understandable. I did check out the older version that has 'em, but I still preferred to ask in case much has changed about them or I ended up missing something. The variety is insane on those tables and so they're definitely a must-have for me :) will definitely keep using them.
Hi JeansenVaars, I think the product looks great, unfortunately, they have recently disabled PayPal in Thailand for non-Thai's. Is there any other way I can get some funds to you?
Cheers and happy festive season:-)
Thank you, Opus, don't worry so much. Your thanks and liking this product is already a huge thing for me. Please enjoy it, and why not share an actual play someday :)
Thank you! I'm excited to try this and PUM!
Ooh I love the look of those d100 tables! For some reason I keep finding myself gravitating toward big tables of adjectives (I constantly need to know things like "What does this cool new item look like?" and "So we found some kind of building in the wilderness, but what is it?") and the one included here will give a big boost to my collection. 😃
And the subject/topic table is great for "What does the NPC talk about?" and "What's written in the letter?" or "What does the inscription say?"
Thanks for the great resource!
Thank you for your kind words! Indeed, the Inspiration Prompts tables should definitely help with those kinds of questions. Complement them with yes/no oracles of PUM to refine them afterwards :)
