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

- 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!


A Brilliant mind boggling game. I did have a few problems as many other people have, with level 7 and 10 with the missing option in the drop down bar.
DO NOT USE CHROME apparently that is the source of the problem and works on different browsers

Good game but Christ are those last few questions complex. Some of the grammar and semantics don't match up in the dropdowns which makes it VERY hard to construct the answer. The machine logic question essentially being one statement and then a mess of dropdowns with little to no connectivity doesn't help much. Really disappointed it came to that in the end.

excelent and well thought out, very entertaining

Excellent but very frustrating.

Add a scroll bar on the drop downs. I couldn't figure out what was going on there for awhile. Once I discovered there were other options that I couldn't see things became much easier logically. However, when I pressed the down arrow it would change all the answers in the column - causing me to have to resolve multiple logic problems over again. Usually I would forget that I had to re-correct them to begin with and would get the answer wrong multiple times before I realized the error.

Aside from that, it was a decent logic game. Different than any that I've ever played so it was enjoyable. But the controls had me on the verge of quitting many times. For that reason I couldn't go any higher than a 3/5.
