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 website:
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!

Tough but fun.


Rated 4.5 / 5 stars

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)

Well I thought the game was awesome. I loved the concept, enjoyed the premise, and I even enjoyed the mystery surrounding the ending (involving your captors), though i have my theories. I have prior training in logic though, so perhaps the concept was a bit easier for me. I look forward to your next submission.

i like the consept but your logic is flawed. seeing that logic is the whole point of the game, i give you a two.


Rated 5 / 5 stars

Very clever, very twisted and very fun. There was definitely a 'portal' vibe going on with the test subject talk and the slightly off-kilter machine. Too bad we never did escape or find out who we were.
I do wish I had read the summary about the arrow key business ahead of time though, I almost drove myself nuts on the logic problem proving Micheal Atkinson is a douche because I couldn't see half the answers. Is there any way to make that more obvious, or add it into the game/menu screen just as a heads-up to players?
