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

- 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!


I love logic based games, and this is one of the most logic based games i have ever seen(except the political question and red-herring one, as you had to know some insight to actually deal with these question. Don't get me wrong, i know you can solve those without knowing those two things(which i did) but it was still annoying) AND i have to be honest, in the very last puzzle, i guessed the third answer(correctly on the first try hah!). But all those weird symbols just screwed with my head to think straight.

I can't agree with the previous poster at all though, every puzzle had only one real solution, a logical one.

One downside though, the navigating(clickin on screen) wasn't that good, especially considering you couldn't go back if you accidently clicked a message away.

P.s.: I never solved a puzzle with the hints...i looked at one hint just to see what it was about, it was far more confusing than just to deal with the question on your own, just with plain logic.

This game is pretty freaking awesome. I like the idea of logic being the gameplay. The music is freaky and creepy, which fits the theme. Also, marmite is best with cheese xD

Great overall game (I loved Penumbra, so I immediately knew I'd like it). The levels get a bit annoying, since at some point I just started putting them in random orders in hopes of getting it right, but the story itself was well thought out.

Best flash game I've played for some time, very entertaining and a bit hard too.

Please, PLEASE!! Add a scroll bar or something for the drop-down menu!! On number 7 I couldn't figure it out until I read a past comment saying that there are more options below!!!!!
Other than that I really enjoyed the game; it really made me think, I even had paper out and was writing equations lol!! 4.5/5 (-.5 for lack of a scroll bar!!!!! :o)
