On Natural & Artificial Games

Can we use the terms natural/artificial for games, in general?

One way to look at this is to relate naturalness to simplicity. Simple games like Hex, Tic Tac Toe or, perhaps, Go, seem almost like discoveries, rather than inventions. But the fact that Hex was only "discovered" in the 1940s does give us pause to ponder. Simplicity is culturally dependent, just as are more obvious or trivial things - e.g. the positional numerical system, or the moral statement "slavery is wrong" -- which were not so in the past.

Another way to look at this is using History. Games, or game concepts, that seem to be invented independently are, at least, cognitively attractive to humans. Perhaps they are cognitively attractive to conscious beings in general, and so, they may even exist in alien cultures. Some examples of those are race games, or Tic Tac Toe/Gomoku variants. Possibly, seed games, Mancalas, also belong here. So, a natural game would be an instance of one of these archetypal game concepts. Of course, as usual, the frontier is blurred. Bao is a very complicated Mancala game. Overly baroque variants can hardly be seen as natural. Shall we include Checkers/Alquerque or Chess games? And how many add-ons can a game include and still be considered a natural one?

A third way to try to make sense of this separation between natural and artificial, is to look into the game's history.

Games like Chess, Go, Mancala and Checkers have evolved through centuries, absorbing gaming experience into their progressive adaptable rules. As in biological natural selection, these games are more like species, with their life trees,
their historical compromises, their multiple branches (cultural instead of biological). So, in this case, every game started in one or more human minds, in some raw artificial state, and was tested in a social environment. Like most species, most games must have become extinct quite quickly. But a few were able to adapt to the cultural intricacies of the memetic landscape of its inventors. And then, when society changed, games also changed, like any adaptable, flexible population of organisms. Of course, the analogy only goes so far. Unlike fossils, if they are rediscovered, games can be brought back and enjoy a new life eventually under new clothes. (The Game of Ur, and Senet, with their reconstructed rules, are famous examples).

Just as for the concept of species, we might differ our final judgement about our recent games. Perhaps Hex will have a biography (it already has thriving children, like Y). Game inventors, nowadays, have an immense set of game ideas and, like alchemists, they try to mix them, mould them into new games. Most of those, as in the past, will become extinct and never get beyond being artificial concepts. Others, because they say something to generations of players, will be carried along with our evolving society and will start to have a biography. They will, slowly and in unexpected ways, become natural concepts.

Board Games Studies 2011

This year edition of BGS happened in Brugge, Belgium. The meeting was held at the KHBO-Spellenarchief. The game archive has several thousand board games and has a database (in Dutch) which is being slowly uploaded with game information and, hopefully, game rules. Here are some pictures from their public section:



And here is a panoramic view (as usual, click to enlarge):

Lots of thousands of games were donated by the Dutch game collector and inventor, Fred Horn, who still collaborates with the Museum. Here is a picture of him (the middle guy, talking math & games with Jorge Nuno and Carlos Santos, two Portuguese friends):

Irving Finkel presented "On to Square Two – the question of dissemination" talking about how games travel between cultures. This travel is useful for game survival but has also the problem of game contamination. Some games may even replace and destroy old games. For a game Historian the modern waves of European migration (like colonists or missionaries) to the rest of the world meant terrible news.

In the colloquium a participant (I don't recall his name...) presented a rediscovered picture from an old book, picturing Adam & Eve in the garden of Eden. Some say they are playing a board game (I saw just them picking and eating grapes or something like that...). Anyway, the picture is pretty:


Michel Boutin made a nice presentation called "The structure of games" were he made an historical perspective of how games were classified in the past.

Anyone knows Dutch German?

[Feb 2013] Fred Horn was kind enough to translate the rules:

Game-Rules

A Tactical Game for 2 Persons from 8 years on, with both two Knights and nine Squires.

Aim of the Game is to get your Knight occupying the Opponents Knights’ start-position; or tocapture the Opponents’ Knight by jumping over or in the same way capture all Opponents Squires.

The two Knights (Balls) start, at the beginning of the Game, on their same colored Field (Cirkle), the nine escorting Squires start on the 9 surrounding yellow Fields (Cirkles).
Players draw who begins and then Turns go alternately by moving in his Turn one Piece of the Players’ color. Moving goes in all directions, including diagonal.
A move is only to a next, free adjacent Field (Cirkle).
When it is a Players’ Turn and an Opponents’ Piece is adjacent to one of his Pieces and the Field (Cirkle) behind is empty, The Player MUST in this Turn jump over the Opponents’ Piece.
This Piece is captured and removed from the Board.
Does the Players have more than one opportunity to jump he is free to choose which capture he wants to make.
Only one Piece can jumped over and it is not allowed to jump over your own Pieces.
Knights can move or jump to all Fields –a color does not count-, but Squires are only allowed to occupy their own yellow Fields(Cirkles)-their start-position- or the grey Fields(Cirkles) =No-Mans-Land=. The Squires may jump over an Opponents’ yellow Edge only, when after the jump they occupy a grey Field (Cirkle).

Winning is by 
  1. capture of the Opponents’ Knight; 
  2. capture of all Opponents’ Squires or 
  3. moving the own Knight on to the start-position of the Opponents’ Knight.

The Siege of Paris

At 1870 Paris was sieged by Prussian forces and, in four months, took over the city and won one of the n wars between France and Germany. In the UK it inspired the creation of a game called appropriately "The Siege of Paris" (the game appeared also at 1870). Here's an original box (available at the Oxford Digital Library):
Here the initial setup:
and a better view of the board (from BoardGameGeek):
Also, at Oxford Digital Library, here the scan of the original rules (click to zoom):

At BoardGameGeek there's also the rules in text format:

The Siege of Paris

This interesting and amusing game of skill can be played by two, three or five persons; one takes the Garrison or Fort, the others the outside lines.

The positions of the Men are as follows :- The General on the right, the Colonel on the left, the Captains next,and the Lieutenants in the centre ; the placing of the Men in the Garrison is optional.

RULES OF THE GAME
1.-The Besieging party have 36 Men,viz., two Generals two Colonels, four Captains, four Lieutenants. to be equally divided, and to be in two colors, half to move on the Black Squares, and half on the White.
2.-The Besiegers cannot move backwards, Officers or Men.

THE MOVES OF THE BESIEGING PARTY
3.-The Generals move on White or Black Squares-one, two or three Squares at a time. straight, sideways and diagonally.
4.-The Colonel moves on White and Black Squares-one or two squares at a time, straight or sideways.
5.-The Captain moves on White or Black Squares-one square at a time, straight or sideways.
6.-The Lieutenants move diagonally-one or two Squares at a time.
7.-The Men move only diagonally whichever Square they are placed on.
8.-The Besieging party win the game by placing one Officer and three Men in the Garrison, and cannot be taken when inside.

RULES FOR THE GARRISON MEN
9.-The Garrison is occupied by eight Men, viz., one General, one Colonel and six Men, and win the game by taking 24 Men and six Officers.
10.-The Officers and Men of the Garrison cannot be taken, but the Men can be blocked in by the Besieging party, until they are relieved by their Officers.
11.-You are not compelled to take any Man; when any of the Besieging party are taken they must be unsupported, and place your man on the same Square.
12.-The Officers and Men of the Garrison to be Red.

MOVES OF THE GARRISON MEN
13.-The General can move any way-backwards or forwards, straight, sideways or diagonally, and take the same way one or two Squares at a time, either on Black orWhite Squares;
the Colonel moves on Black or White Squares, backwards or forwards, either sideways or straight, and takes the same way;
the Men move diagonally only, three on the white Squares and three on the Black, either backwards or forwards when outside the Garrison

Entered at Stationers' Hall

R.C.Bell provided a patch for solving some problems with the original rules (from BoardGameGeek):

Necessary additional rules and definitions for Siege of Paris. V1.0 May 2009

Win conditions
Garrison player: Capture 6 Besieging Officers and all Besieging Men.
Besieging Player: Having 1 Officer and 3 Men inside the Garrison. (Besieging pieces can not be taken once inside the Garrison.)
Or by blocking with Besieging pieces all legal moves by the Garrison forces. (Supported Besieging pieces can not be captured.)
Alternative win condition for Besieging Player: 1 Officer and 2 Men inside the Garrison.

Draw condition
When less than the pieces required for the chosen win condition remain on the board, then if 1 Besieging piece, or more, are inside the Garrison the game is a draw.

Starting position of Garrison pieces: These pieces may be arranged on the nodes inside the Garrison however the Garrison player wishes.

Turn order: Garrison, White, Garrison, Black, Garrison, White, ...

Alternative forced taking rule: The Besieging player can, if such a move is legal, command the Garrison player to take a Besieging piece.

Fort Gate: Entry to the fort is from the 2 squares (1 black square and 1 white) adjacent to the gates on each side of the fort.

Support: Besieging piece "A" is "supported" when another Besieging piece could legally move onto the square occupied by "A" but for the presence of "A". (Supported Besieging pieces can not be captured.)

Capture: As in chess, by moving the capturing Garrison piece onto the square occupied by the Besieging piece. (Garrison pieces can not be captured.)

Three old Knight games

At Michel Boutin presentation in the BGS, he mentioned a lot of 19th century board games that were patented in France, UK, Germany and in the US (and most already forgotten). Here are three related games using the Chess Knight, grouped together in a package called Rampant Knights.

These are the board (click to augment)

I found the rules at a Hoyle games edition. Here are the relevant pages:





He also mentioned a board game called "Jeu du Congo" (Game of the Congo) with a hexagonal board:

which was re-edited by Moulin in the French book Jeux de pions d’aujourd'hui. The rules can be found at issue 8 (Winter 2001) of the Abstract Games Magazine.

The Game

Fred Horn showed me a picture of an old 1970/80's abstract game called "The Game"

He mentioned the rules orally, as he remembered:

The board starts empty and each piece (each player has five) enters in the player's corner.

On each turn, each player enters a piece off board or moves one friendly piece.

A piece moves [up to?] five cells in orthogonal directions with, at most, two changes of direction [no jumps allowed, it seems].

One piece may land in top of another. The pieces not in the top of a stack become blocked.

A stack can have, at most, three pieces. When a stack of size three is made, the piece in minority is captured.

When all the player's five pieces are on the board, the player cannot stop a friendly piece in his own corner (but it can move the piece thru it during the move sequence).

Wins the player that moves one of his pieces to the enemy's corner.

Any extra information about this game is appreciated.

Games @ BGS 2010

In the Board Games Colloquium (BGS) it is always easy to find new abstract boards and ideas about games. Let me give a sample of this year, in Paris:

Herein you can see a game from Fred Horn, which basically can be seen as a Mancala kit.

These squares can be placed in any order the players like and every mancala board can be built this way. Of course, this game material can be used into many other types of games.

Here you can see Fred Horn (in the left) playing Fianco, another of his games:

A very interesting game is Nonaga, a 2008 invention by Víktor Bautista i Roca:

Visually, this reminds Zèrtz, but in this case, we have a pattern game and the board only changes shape (it does not decrease in size as in Zèrtz).
