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!

not that original


Rated 5 / 5 stars

Awesome game! Make more of these. The 10th level was the best!


Rated 3.5 / 5 stars

An excellent concept. but that loud-ass noise that plays everytime you click the button to answer kinda fucked it up for me.


Rated 4 / 5 stars

Good game, but there's something I don't understand. ---SPOILER BELOW---

If you're alive, how are you breaking the laws of human biology?

tjubert responds:

You're not. EITHER the laws of biology have been broken OR you're breithing oxygen.

Just, this.
I LOVE it.
This is one of the most original things I've played in a while. It was really well done. The way you did the hints was good. The very last puzzle was a beech, and I'm still not sure if I entirely get why it worked, but this is still an epic game. I want MORE.
1. I like this game.
2. IF I like this game, I should give it a five out of five.
3. THEREFORE I will give this game a five out of five.
