Chess Motifs: Not strictly, since there isn’t chess, but the locals can and will treat you to a generous selection of larileth, iandaër, and kírasseth motifs – as seen, in the third case, in the title of “Princess of Clouds to Archetypes, Gilek-Four – Your Move“.
Calvinball: An awful lot of games played in the Empire are like this from our perspective, by virtue of having been designed to satisfy the game-playing urges of people with, well, transhuman intelligence. For example:
One of the simplest is the card game ómith. It’s like poker, except with six twelve-card suits on an elemental theme that the game itself shares (the suits are clouds, coins, droplets, flames, pillars, and staves) and a major arcana, plus a variety of metarules and dice-controlled variations, and a scoring system with an incredible number of special cases.
Larileth, or sigillary, which would most closely resemble mahjong, had mahjong been based on a set of combining rune-constructs devised to reflect the aspects of the universe as defined by (in Earthly analogy terms) a mash-up of Hermetic magic and qabala.
Ithréth, which is a sort of dynamic four-dimensional go, metaphorically speaking. (The lack of four-dimensional playing boards and four-dimensional spaces to keep them in adds an extra level of complexity once people start making moves ana and kata, which is where much of the true subtlety of the game lies. It’s much more pleasantly complicated than the “four-dimensional” games in which pieces just time-travel, for example.)
Iandaër, which is a battle simulation game that is on the one hand like chess, but on the other hand resembles taikyoku shogi rather more closely. It is thorough.
There’s also mírlathdaër, the favored game of AIs and other digital sapients. Which is essentially Nomic, only as played by entities which can successfully manipulate rule lists gigabytes or even terabytes in length in real-time. (For extra fun, there’s the simulation version where you do this with physical laws, and the point of the game is to create the most interesting simulated universe. The only acknowledged win condition for that one is to get intelligent life to evolve in the simulation without using any special cases; no-one’s actually won it yet.)
And then there’s kírasseth, the generally acknowledged monarch of eldraeic games; it requires several interrelated boards, sets of cards, dice, and some specially made mechanical computer-randomizers, it is self-referential inasmuch as the players, the rules, and the game itself are all also pieces within the game, to play with any degree of competence requires an astonishing mastery of everything from scientific principles to mythic symbology, and its most commonly used set of victory conditions include that any win which is insufficiently elegant and aesthetically pleasing is actually a loss. It is, of course, incredibly popular – at least to watch.
One loophole opened up by the Empire’s lack of any gambling regulation is that it is entirely legal to run crooked games, provided that you tell people that they are crooked games (and therefore are not committing fraud by doing so; whether or not there is money or other property involved).
Some curious institutions that has grown up in this loophole are the urlisdaër (“false-games”) and the associations which exist to play them. The urlisdaër variant of a game – most commonly ómith, larileth, or iandaër, although any game with rules can be played in the urlisdaër manner – is played exactly as it usually is, save that the players are permitted by the metarules to cheat, and indeed, are encouraged to do so as effectively as possible.
When one player detects another cheating, he may either “call” the second player out on it, in which case that player loses his gains from it and the use of that method for the remainder of the game; remain silent and cheat using his own methods to nullify that player’s advantage, while letting him continue to have it versus other players in the game; or find a technique to turn the second player’s cheating to his own advantage directly. This latter is the most difficult option, but considered the most estimable among masters of urlisdaër gaming.
At the end of such a game, each player retains the profits made from his individual skill. In association play, many groups additionally discuss each player’s techniques and award additional rewards from the table to those deemed most subtle and elegant.
