**Webpages**

- SIMOMaths’ Combinatorial Game Theory A course on basic CGT for High School students in the form of blog posts.
- Combinatorial Game Theory (Blogspot) A blog with a lot of interesting thoughts/tidbits about CGT. Many posts require some background, though.
- miseregames.org A webpage with tons of useful links for those interested in the theory of misère games.
- “Games of No Chance” series PDFs of selected papers on CGT; they are also in book form (edited by Nowakowski, and later, Albert as well).

**Books**

- Surreal Numbers by Knuth. It is a rather accessible mathematical exploration that both teaches what the Surreal Numbers are, and teaches something about how mathematicians work, by getting a layman reader involved.
- Foundations of Analysis over Surreal Number Fields by Alling. It is a text requiring a formidable background in mathematics (an advanced undergrad with significant background in algebra and real analysis might be ok) but which goes through the detailed theory of the Surreals very well.
- On Numbers and Games by Conway. An introduction to number systems and some theory of partizan games with more proofs and fewer examples than Winning Ways.
- Winning Ways by Berlekamp, Conway, and Guy. A fairly comprehensive introduction to CGT in four volumes with tons of examples, although it’s a bit light on the proofs and doesn’t have a great selection of exercises like a textbook would.
- Mathematical Go: Chilling Gets the Last Point by Berlekamp and Wolfe. A decent introduction to CGT as applied to the Asian game of Go. It can get a little hard to follow if you don’t already have a bit of a background in Go and CGT, but is still a good book.
- The Dots and Boxes Game: Sophisticated Child’s Play by Berlekamp. A collection of Dots and Boxes problems with some of the theory behind it. I hear it’s a bit difficult to read, though.
- Lessons in Play: An Introduction to Combinatorial Game Theory by Albert, Nowakowski, and Wolfe. An excellent book covering some of the basics from Winning Ways vol. 1 in the style of a textbook suitable for a course or self-study.
- Combinatorial Game Theory by Siegel. An amazing book covering essentially everything important. It’s a graduate textbook only because it doesn’t have the wealth of examples/games that Lessons in Play does. It’s written very well, though.

Above I have listed the stated authors for these books, but in some cases there may be controversy over who was responsible for which ideas, and who had permission from whom, etc.
