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!



Rated 5 / 5 stars

something very special here. You've taken a vaguely point and click game, a genre I typically find dull, used one of it's most cliched tropes of being locked in a room clueless, and made it into a truly superb experience. The logic puzzles are really quite interesting and ramp up in difficulty quite well, and the music in the background is perfect. It's a fun track to listen to and fits this odd little puzzler flawlessly. Keep up the good work.

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


Rated 5 / 5 stars

Amazing logic game. It really gets the mind thinking. Some parts like the last were quite confusing. I thought that every of them appied for each other so I was confused but then I realized they didn't & won. Took me around 20 minutes to do the whole thing.


Rated 5 / 5 stars

I don't think I've ever had to think this hard when playing a game before. I love it :D I got them all on my own eventually. Great game.

Wow, nice game! I kinda guessed the 3rd line of the last puzzle, because I don't think it makes any sense... Anyhow, great job, keep it up and maybe make a sequel! :)

I'm considering putting more mistakes into the next version of the game to encourage people to talk about it!
