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

- 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

People find this review helpful!

if you think long enough about a question the logical answer will show its self wether or not you are logical human being or not... (possibly my highest rating for anything ever congradulations)

Loved it ! Awesome brain teasers ! .. The last level game me a brainxplosion ...

My only problem with this is that you seem to try to prove the existence of god through circular reasoning, circular reasoning is a fallacy therefore you havent proved god exists in any way because it's just like saying if god exists then he exists which is dumb

tjubert responds:

Glad you enjoyed it.

If you read the level goal for that argument you'll see the goal isn't to prove anything - just to make the argument valid. An argument can be logically valid without being true or informative.

i luv syllogisms
