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!


I really liked this game, it was interesting and challenging, I look forward to more of your games.

Interesting game. I think people who deal with logic often will find the game a light brain teaser, but those who do not will struggle with the "new" concepts to them. I enjoyed the game and music within, I just would have liked to have been challenged a bit more towards the end.

got really hard on oxeygeon part

i dont understand, it wont let me go past the part with "the assumption that a perfect god exists" part, and i feel like some of the screen gets cut off in the window.

This game, or at least the levels it were let me play, was/were good. The only problem seems to be the Atkinson puzzle. For some reason instead of what line 2b (then loop) had to be, "Australia is wrong to ban 18+ games", there was just "Atkinson parks/does not park in disable parking spaces" as an option. I double-checked with the walkthough and the Australia line is needed, but I can't get to it. Am I doing something wrong or is this just an error in the game?
