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!

really fun, at the last puzzle, I looked at it, said wtf, looked at it again, thought about it, used logic, still felt like I was guessing, but got it right on the first try.

Cool mind-benders and fun story~ Warning, approach with a fresh brain.

A bit glitchy, remember to scroll down to see all the options to complete the questions. They are not always visible.

Brain tired now :-/

I do enjoy this game very much. And I did have the problem with the answers in stage 7 not being available with a Google Chrome server. I HAVE FOUND A SOLUTION!!!! Select the box that you think should have an answer that is not appearing, USE THE ARROW KEYS TO SCROLL THROUGH THE OPTIONS. Continuing downward will reveal answers that were hidden. You're welcome.

one of the best games ever

This is a great game, and I greatly enjoyed playing it. The story was very compelling, and the puzzles both interesting from a political or story standpoint, a humor standpoint, as well as pinpointed the best difficulty.


The game has one very crippling bug: occasionally options will not show up. This happened to me for the CORRECT option - twice. This was my second playthrough, so I remembered some of the puzzles' solutions. On Level 7, the second "if, then" needed was (spoilers) "If games should be compared similarly to film, then Australia is wrong to ban 18+ rated games. The option for "Australia is wrong to ban games" was not listed.

The same happened on the final level (which, by the way, is unskippable if you want to see the game's ending) wherein the options O and Not O were not shown. O is the answer, meaning I could not see the ending (not a big deal for me; I already know the ending, but knowing others cannot see it is... painful).

From the reviews below, this is a very common problem. The only thing that comes to mind is that the first time I played it I used Mozilla Firefox, while the second time I played it in Google Chrome, so it may be a browser issue. To those below with a similar problem, try using Firefox and see if that works.
