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

Instructions:
- 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!

This game is absolutely amazing and was completely worth the hour or two I spent playing it. I was surprised at how well I was able to figure out the puzzles, considering I only had to "use my brain" on puzzles 8 and 10, and 10 just stated the things I already knew. This is a fantastic game, and everything, the music, the gameplay, the plot, fit together extremely well.

This was spectacular. It was hard, and at times I found myself not being able to keep my mind on track because I was thinking so hard, but it's entirely solvable and not in the least impossible. I wish we were taught things like this in school, using a puzzle system such as this game, to learn problem solving skills.
Gawwwwsh I loved this game. Thanks, mate. It was a pleasure.

Seriously, I fucked my mind up to solve the 7th puzzle! There isn't the correct option: "Australia is wrong...". Why? I had to find a walkthrough in order to solve the puzzle and discover that the Australia option is not in this version of the game! Jeez.

I love the concept, but the drop down menus are terrible, the puzzles often didn't accept perfectly logical arguments that differ slightly from your template.
Also the dialog kinda felt a little condescending by patting you on the back for every frankly, pretty easy logical puzzle you solve.

I'd like to see a more polished version of this with harder puzzles and a better input method. (possibly fields to type in freely using variables predetermined by you?)

When you are cornered in a circle, triangulate it.
