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 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!

Thanks Alot! This is the topic we are learning from our Math subject (Geometry) , its called Deductive Reasoning. People who are smart in math and haven't studied this lesson will probably pass this game. Unless of course for the 10th level, you would really need to study the symbols of it.

This was... interesting. Certainly very mind bending. I also like the ambiguous twist at the end. Will there be a sequel? I certainly hope so.

This is, undoubtedly, a god tier game. Because of this game I will begin using logic more throughout my days. I am doing it right now, by stating facts in short sentences. You have done well in the construction of this game. A sequel would be appreciated.

This game really made me think... a lot. The entire sequence of the game being mental stress, followed by a (terrible) relief lead me to believe that nothing has any meaning. Great game though!
