A checkers' variant for kids (sent by Fred Horn):

And zooming the rules:

Colorito

Colorito is a 19th century game. Boardgamegeek has the following description:

 Each player has 20 numbered pieces / counters of two colours (blue & red or brown & yellow), which are put on the two first rows of a 10×10 grid of octagons (topologically similar to squares, but without the diagonal adjacency). The fields of these rows are numbered from 1 - 20, so each counter has its definite starting place, making one complete row of either colour. The spaces of the central six rows are coloured according to the counters, either red, blue, yellow or brown, and build up a regular pattern. Counters can step one space, jump across one other piece (also more than once during a turn) when landing eventually on a space of its own colour or doing a step plus a jump move in this order in a turn. Aim of the game is to get the pieces on the opposite side onto the octagon with the corresponding number (similar to Salta, which maybe adopted this idea from Colorito). This game was one of the favourites of Grand Duchess Anastasia Nikolaevna of Russia, mentioned in several letters/diaries about 1915.

Fred Horn sent me photos of two of his sets:

(as usual, click to enlarge)

The rules, also from bgg:

There are three basic moves:

1. the step, in which you can slide a counter in any direction into an adjacent octagon and stop there, provided that it is the same colour as the counter, or white (i.e. at the ends of the board);
2. the jump, in which you can jump over any counters in any direction as long as the octagon you finally end up on is the same colour as the counter;
3. the slide and jump, which combines both moves, meaning you can slide to any one adjacent octagon whatever the colour to start and then jump in the same move.

Although you are competing against another player, you are also partially dependent on each other, and game strategies are an interesting balance between exploiting your opponent for self-interest, and blocking your opponent. There are certain combinations of moves, particularly in the openings, which are optimal for a good middle game, and the end game also needs good planning to get the counters onto the right number octagon at the other end.

The winner is the one who has used least number of moves to get all his/her counters in the right places. Sometimes it is necessary to bring some counters out into the midfield again, in order to bring stragglers home.

The family of Foxes and Geese

The Fox & Geese family is a big one. There are multiple variants from everywhere with different board topologies and different types of unequal armies. The following images came from http://hong.vlinden.com except when noted.

Here's a 1880s variant called Siege Game:

Another example with the same name from around 1900:

And with a hexagonal board:

Fred Horn sent me a beautiful variant called Avro Eigen Zender Spel:

The Game

At May 2010, I posted some partial info about a 1971 game called "The Game". This week, Fred Horn sent me an email with much more information because Piet Notebaert from Brugge sent him a scan out of the gamebox. Thanks Piet and Fred for this data :-)

Tue rules (in Dutch)

Fred was kind enough to translate the rules to English. He also included some extra rules that he used while playing:

THE GAME

The Winner

The Winner is the Player who succeeds in occupying with one of his Pieces
the start square –Basis- of his opponent in his Turn.

The Rules

1. The Game is played by two players each playing with five identical pieces.

2. Both Players start with their Pieces off the Board.

Their Basis is the square with the same Image as their Pieces.

In their first five turns, the players alternately bring their Pieces upon the Board, starting the Moves on their Basis. 

Draw decides who plays first. 

A Move is done by sliding the Piece horizontally or vertically over five squares of the Board. 

Moving diagonally is not allowed.

During his Move a Player may change direction 2 times, but cannot return to its start-square/-position of this Move.

3. After five turns each Player moves one of his Pieces in his Turn.

4. Players try to reach the opponents Basis by alternately sliding their Pieces.

5. It is not allowed to jump over a Piece.

6. When the last square of a Move is occupied by an opponents Piece, the Player can place his Piece on top of the opponent to neutralize and immobilize this Piece. This Piece cannot move any more until the Piece on top has moved on.

7. Only when the blocked Player can move another Piece on top of these two, the blocking Piece is now the minority on this square and is captured and removed from the Board and out of the Game.

8. A Player is not allowed to hold – occupy with one of his Pieces - his Basis for more than three turns.

9. If a Player has occupied his Basis and the opponent ends upon it in his Turn, this is not a winning Move. The Basis is only neutralized and there is only a win when another Piece lands upon these two to capture the blocked Piece. 

When this is not possible, the Basis first has to be freed from Pieces before it can be occupied again.

N.B.  The rules do not forbid the occupying of a square with more than one Piece of the same kind.

Additional Rules by Fred Horn.

We played the Game with some extra Rules:

• It is not allowed  to occupy a square with more than 2 own Pieces.
• It is not allowed to occupy your own Basis with more than 1 own Piece. This means that a Player cannot capture on its Basis.
• It is not allowed to pass a square for the second time during a Move.
• There is also a WIN when all opponent’s Pieces are blocked.

There was a Xiang Qi:

A board of Makru, the Thai Chess:

And a strange board that I don't recognize (the label was wrong, it said that was the Makruk which cannot be right):

CROSS

Game by Cameron Browne (2009)

CADUCEUS

Played on an 8x8 board, each player starts with two stones, at opposite corners.  
Group-restricted 12* moves per turn.

For each move, a player removes the tail of one of his groups, then adds two successive rookwise-adjacent new stones on empty cells at the head of it.

A player loses if he cannot complete a legal turn.


The first moves (the '-' clarifies the chain structure):

                       _J___N_    _B___T_

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.

Two Games for Three Players

Here are a couple of games to be played with three players:

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.

Fehde

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.

This game is based on Atoll, a game from Mark Steere

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):

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.)
