1. Top Pick Overall: 100 Days of Logic
Made up of short 90 second videos this course covers everything you would learn in a College logic class and more. You can watch the videos on YouTube or test your knowledge with the interactive courses on Carneades.org, including separate courses for Propositional Logic, Categorical Logic, and Predicate Calculus. They explain concepts that take some lecturers hours to get through in a matter of minutes, and have quizzes throughout to test your understanding.
What really sets these courses apart, is that they have follow up playlists that cover more advanced topics in Deontic Logic, Temporal Logic, Epistemic Logic, and Set Theory, subjects you would not otherwise see outside of a Doctoral program in philosophy. These complex topics are covered in the same accessible way, using the same notation. meaning you can start these courses with no understanding of logic at all, and walk away being able to perform PhD level proofs.

2. Best Proof Tool: Stanford University
This course uses Stanford's interactive Fitch system, which allows students to do proofs by selecting premises and clicking buttons to apply rules of inference. It is a very unique system that makes doing a proof much easier and more accessible. However, the course itself has few video lectures, with most of the work being focused on reading then applying that reading to the proof tool. A great option for those who can learn by reading and interacting, but more difficult for folks who want a video lecture to talk them through the concepts.
One advantage of this course is that, since it is largely written, it has been translated into 22 different languages, and the nature of the proof tool makes it a good interactive option for anyone that likes to learn by poking around with something. There are two different versions of this course one, on Coursera, makes full use of the interactive tool, but costs $95. The other is free, hosted directly on Stanford's website, but has less functionality.

3. Best Gamified: Brilliant.org
Brilliant.org has improved their offerings on logic in the past several years, moving from just puzzles and games to include some coursework on proofs and formal logic, though these are still more geared towards math or computer science than philosophy. If you already subscribe to Brilliant for their other content, you should definitely check out their logic offerings as well. But if you just want to learn the topic, the price-tag for Brilliant may be a bit steep given that there are free options available.
One thing to note, Brilliant has a great collection of logic games as a part of their courses, so if you are looking less for a formal course and more for some creative and interesting logic puzzles, it may be a good option for you.

4. Best Production Quality: Great Courses
Great Courses has a series that provides an introduction to formal logic. While its trailer is very flashy, it does have some quality lessons in the middle that dig into the technical depth of formal logic. It also has the advantage of providing two lectures at the end on more advanced topics like Modal Logic and Fuzzy Logic. The drawbacks are that this is just a video series that you are buying, not an interactive course that might be helpful for some to digest the content more.
The lecture series is offered as a single course for $49.99, or you can get it by subscribing to Great Courses for $14/month. If you already have access to this subscription, or want a more engaging video series for a single payment, this may be the right choice for you.

5. Best Inductive Logic: Duke University
Duke University's four-part course series on logic includes components on deductive logic, inductive logic, and more. This course series is recommended for its inclusion of inductive logic, including Bayesian statistics, something not included in many other logic courses. The courses have challenging quizzes and lectures which some students have found difficult to understand or complete, but if you are up for a more difficult introduction to logic, this may be for you.
The course series is offered through Coursera, but you will need to sign up for a $49/month subscription to get access beyond the trial information. While this does provide you with a certificate of completion, it may not be worth the cost given other cheaper options available.
