Argue the toss in a twisted tale of logic...

In ir/rational you complete, create and discredit arguments by selecting propositions and filling in the blanks. It's a puzzle game based on propositional logic, and a graphic adventure all in one - only here you don't so much need to escape the room as prove why you'd even want to.

- Unique, language-based argument system: formulate logical proofs to progress through the game

- Dark philosophical comedy by Tom Jubert, writer of Penumbra, Driver: San Francisco and FTL.

- 10 screens and roughly half an hour of intelligent, challenging and inventive gameplay

- Musical score by award-winning composer Mikko Tarmia

My website:
My narrative design blog, Plot is Gameplay's Bitch:

- Click to progress story
- Complete the arguments by selecting options from the drop-down menus

NB Some systems don't display all the dropdown options at once, and you have to use the arrow keys to scroll.

If you can't see the right answer, chances are you can resolve the problem with the arrow keys. Hope it's not dampened your enthusiasm!

Yay! I knew philosophy would come in handy one day :)
This is a fun way to introduce people to the proper presentation style/thought process used in philosophy.
HOWEVER, I cant rate this 5 stars because I disagree with one of the questions...
in Q9, the machine could have been saying 'yes' to the fact that YOU are indeed wondering if the smugness is a relevant clue, and not to the potentially false statement that the MACHINE thinks the smugness is a relevant clue.

You guys should make a sequel, though.
1. I want a sequel
2. If you a gamer/game maker/philosopher, you should obey my whims.
3. You fulfill at least one of those roles

the game was fun and the atmosphere was nice. the problems can be solved with basic knowledge of logic. without that, it might be hard for statements to make sense. i agree that the ending was a little too empty. the game should answer the questions if it's going to raise any. at the end of the game, we know nothing about ourselves, or what is outside the room. why did they even kill us?you might consider changing the ending. but, as everybody else, i enjoyed the game. good work :)


Rated 4.5 / 5 stars

a great idea with a simple idea but very hard at some point
i love this kinds of brain/logic puzzles
would love to see more
however work on the ending its very dispointing
maybe that the character learned how to escape the ending and investegate the test what effect it had?
but hey it was a great game and for a short game the ending has not that much influence on the feeling of the game, it was great and it feels great solving the problem you feel that you got the logic
of the riddle/puzzlel
would love to see more of this


Rated 4 / 5 stars

good game, with great logical points, however, the ending.... a let down. i would recommended (so that i do not give the real ending away) adding onto the questions a very quite way to learn about the player. the way i would do it, is to have a question with many different answers. then have more endings based on those answers. i know i like a game where are a few different endings.
