Open Your Mind

Welcome to the arm chair Logic site. If you are interested in thinking logically then this is the place to start.


Discover your logical powers with two short tests.
Start with Test No 1 and then if you wish progress to Test No 2 or 3 which are slightly harder.
Just tick the boxes and get your scores at the end of each test.
No previous experience of logic is necessary. However, before you start you can see a short guide on logic which will prepare you for the test with some fundamental information. Download the Short Guide
