Multipath Chess Pieces. Suggests adding "multi-path" pieces to leapers and riders classification of pieces.[All Comments] [Add Comment or Rating]Oh, and one more thing regarding jetan rules: The appendix rules were probably not Burroughs' revision of the rules. They were probably the original rules, as written before Burroughs even started on the novel text. The simplified rules in Chapter two clarify nothing, and are interesting only because of the statement that the thoat can jump, not given in the appendix.
Re: Jetan.
Larry Smith, for reasons unknown to me, liked to exaggerate the inconsistencies found in Burroughs' novel The Chessmen of Mars. In reality, there are only a couple of real inconsistencies, although it is true that due to Burroughs' vague wording, jetan has sometimes been played with alternative rules.
Consistent rules can be found in connection with my jetan articles in ERBzine and Abstract Games, and not least in my book Jetan: The Martian Chess of Edgar Rice Burroughs (McFarland, 2022).

Jetan Sarang 
. A large variation of Jetan.[All Comments] [Add Comment or Rating]In my book about Jetan, published by McFarland, the rules of Jetan-Sarang are included in an appendix. That version of the rules are based on a thorough analysis of all available rule versions (including the version on this page) and games of Jetan-Sarang played on Game Courier, and fixes many of the ambiguities built into previous versions.

A couple of comments to George Duke:
First, The Chessmen of Mars was first published in February-March of 1922. The dates you give was the period when Burroughs wrote the book.
Second, the appendix was not added to the first edition book; it was there in the final instalment of the original Argosy publication, and was probably written first, even before Burroughs got started on writing the novel as such. Thus, the appendix rules are not to be seen as an afterthought or a revision, but as the original. Whether the jumping thoat from Chapter two was a mistake, or if it was mistakenly left out of the appendix, or if it was an actual case of a revision, we shall never know.
