Free circuit simulator ?

Here's one from U of T http://www.eecg.toronto.edu/~ali/spice/LTspice/LTSpiceShortGuide.pdf
Afrotech has a 3 part series too:

This is also a good place to go...……… https://learn.sparkfun.com/tutorials/getting-started-with-ltspice/all

Since you asked here in this forum, and assuming you plan to ask/discuss here, then LTSpice.
I'm not saying its a de-facto standard, but its just the common lingo here, especially in this forum.

... Not just here. LTspice was very popular for sharing circuits in the sci.electronics.* newsgroups as its free like beer, not limited to student/non-commercial use, and its schematic symbol and non-encrypted model files are all plain ASCII text, so could be easily posted inline in a medium that didn't really support attachments. As USENET waned and web forums like this grew in popularity, the greybeards brought their expertise and preference for LTspice with them.
If you cant 'drive' LTspice well enough to run other people's sims and tweak them a bit, you'll miss out on a lot here. Even rabid Windows haters and FOSS aficionados should compromise their ethical stance enough to install it under WINE!

I use EveryCircuit on a 10inch Android tablet.
I tested the free version using a single transistor amp, built it on a breadboard and their performance roughly matched.
So I brought the full version which was only a few pounds.
It's limited in circuit space but it's handy to have.
I also have LT spice.

Another vote for LTspice, here.
I suspect the interface feels unintuitive to most people for a simple reason:
The vast majority of GUI based programs use an object-action paradigm, one select the object e.g. a component or wire) then decides what to do with it (e.g. move, rotate, copy).
That capacitor, I want to move it over rhere.
In LTspice, it's the opposite, first one picks up the action, then the object.
I want to move that capacitor over rhere
Once this 'clicks in' the program is easy to drive.
