Ancient Board Games @ The Louvre

Here are some nice examples of race games from Ancient Egypt:

This was the text related to this game:

The obscure Mehen:



And the more known Senet (at least the text said it was Senet, it seems a version, half-way to the game of Ur):



And finally some old, old dice:

Penguins

This is an adaptation of a 2003 commercial game called "Hey! That's My Fish!" designed by Alvydas Jakeliunas and Günter Cornett (*). This new rule set simplifies the game and makes it more interesting.

Rules: 12* move series on a hex-hex board of size 6. The first 3 moves on each side are to place a penguin on an empty cell. After that, the penguins move queenwise, and are not allowed to land on or pass over any other penguin or blank cell. The two moves in a series must be with different penguins. When a penguin moves it leaves the cell behind blank (eaten). If a player cannot complete a legal move, his opponent wins.

(*) the original rules are: There is a hex board where each cell (fish) valuse 1, 2 or 3 points. Then (1) initially, take turns placing your penguins on tiles with a single fish. (2) move a penguin in a straight line of tiles and pick up the tile you just vacated, (3) if a penguin cannot move, remove it. Check Boardgeek for more information

12* TRICOLEUR HEXXAGON

Like Hexxagon, except there are 3 colors (a,b,c) which capture each other (a takes b, b takes c, c takes a).

Win by annihilating opponent; or having most pieces in a blocked position.
Players must leave opponent with a non-pass move, if possible.

SQUARUBORUS

[variant of Ouruborus] Players take turns moving both ends of the slime-worm, each to some adjacent cell. After each move, each end leaves a stone of that player's colour. The worm may not move onto a coloured cell.

If at some point before the board is full, a worm-end cannot move normally, the players continue, making single moves if necessary, until the next player who is able to must split the other end into two heads.

A player wins if he makes a 4 in-a-row with his stones (ortho or diag). If both ends become blocked simultaneously, the last player to move wins.

Sample Game:

J starts: sw.se w.ne n.s e.nw n.n n.ne w.n w.se
ne.se n.s sw.s sw.se se.s s.w s.nw s.s ne.w? e.n & wins

TRIANGLE QUADREX

Each turn, the player drops a tile of 2 of his own pieces and one
opponent piece that are not in deadlock position.  Single pieces
are added automatically as per quadrex rules.     If any cell is
unplayable by regular tiles, it may be played with an overlapping
tile, provided previous colours do not change.

OROUBORUS

Players take turns moving both ends of the slime-worm, each to some
adjacent cell. After each move, each end leaves a stone of that
player's colour. The worm may not move onto a coloured cell.

If at some point before the board is full, a worm-end cannot move normally,
the next player who is able to must split the other end into two heads.

A player wins if he makes a 3 in-a-row with his stones.
If both ends become blocked simultaneously, the last player to move wins.

If, at one end, a player is left with only one move, (either physically
or because all others would lead to instant loss), the opponent who
left this situation must make the single move for his opponent,
and then another move for himself; recursively.

Game sample:

The first move recorded is from the most northerly cell,
and if in same line, most westerly.

GO-6-MOKU with restricted dagger

Rules of 9x9 Go, except that there is no passing and the winner is
whoever gets a 6-in-a-row. Suicide is illegal, except that a 6-row

FLAT-EARTH DOZER-HEX

Like Hex, but lines of friendly stones may push, abalone-wise, smaller lines of adversary stones by exactly their length difference.

If any stones block the full length of a push, the push stops there. A line may push its own length into empty space. Stones pushed off the edge disappear from the game. No friendly stones may be pushed.  Swap option exists.

This game presents an Abalano-like mutator which seems to provide new games. Notice however that this mutator does not use the Abalone rule, since phalanxes can shift more than one cell (based on the difference between the pushed and pushing phalanx).

PRIME PICKINGS

With 1 2 2 2.. modifier, each player picks 2 numbers from the available
number list, crossing them off afterwards.  He may place these numbers
anywhere in his board lists, at most 3 per list, or in an opponent list,
at most one per list.  Once 24 numbers have been entered, scoring is done
as follows:-  the row totals are added for each player, but only
the LARGEST PRIME FACTOR of this is entered as the row total.
The player of the 8th number may not make a tied contest there.

Whoever wins the majority of the three pile contests, wins the game.

This is a very interesting number game. The last moves may become very demanding because each player must search a winning combination in a set of options big enough to be explored.

3/2 HEX

On a unlimited stip of hexagons of height 7, one player (here X) tries to connect the two board edges while his adversary (here O) tries to prevent it.

The connecter plays two stones on each turn, provided that they do not belong to the same group of pieces. The preventer playes three stones on each turn with the same restriction.

If the connecter is unable to achieve his goal in 20 turns, he loses the game.

Damello

[A game between checkers and Othello sent by Giuseppe Acciaro]

The game is played on a 9x9 square board, where both players have 18 stones placed initially on their first two rows. There are four special red squares at D5/D8/B6/G6 (these are the coord given by the author, but they do seem too asymmetric).

Soldiers move vertically and diagonally. They capture with jump vertically and diagonally forwards. Capture is mandatory.

A Soldier that reaches the last row becomes a King, moving like in International Checkers except that it must land in the first square after each jump/capture.

When exactly one piece is between two enemy soldiers (orthogonally or diagonally), it changes color. If the piece is between at least one enemy King, then it is removed from board.

If any piece lands on a red square (either by move or capture) it is captured and removed from the board.

A player wins if the adversary cannot make a valid move.

A Progressive moku

Played on a Go board. Black drops one stone, White then drops two stones, Black drops three, and so on...

A player wins if he makes a 5 in-a-row but he must just drop one stone in his last turn.

CHERRY

Cherry is a Alak variant. First the rules of Alak:

This game is played on a 1-D line. Black and white alternate in placing single stones on a line of n points. If placing a stone thereby removes all the go-liberties of any group of stones of the opposite color, those stones are immediately removed. It is illegal to place a stone where one was just removed. Placing is compulsory if legal, and the game ends when the player having the move cannot legally place anywhere. The winner is the player with the most stones on the board at game end.
Cherry (invented by Bill Taylor, 2008) is played on a semi-infinite line segment where the first cell is marked (*):

* . . . . . . . . . . . . . ...

Wins the player the occupies the first cell with a friendly piece that cannot be captured by the adversary in the next move.

A sample game:

* . . . . . . . . . . . . . ...
* . x . . . . . . . . . . . ...
* o x . . . . . . . . . . . ...
x . x . . . . . . . . . . . ...

X wins because O cannot drop into the 2nd cell right now.

PUSH WOOD

(by Richard Nowakowski, 2003)

Play on a line of N dots (this is an 1D game) each player has M pieces on the line extremes. For e.g., if N=9 and M=3:

x x x . . . o o o


On each turn, each player may:
* move forward a friendly stone to any empty cell or move out of the board (jumps are allowed).
* push a friendly stone backwards if it is backward adjacent to an enemy stone. Every stone in that group is pushed backwards any number of cells until it finds another stone. If there are no more stones, the player may even push out the group or part of the group over the line extreme.
* There is a KO rule: a player cannot repeat the previous position (variant: the player cannot push back any stone that was pushed back in the previous move).

Wins the last player that has a legal move.

A sample:


x x x . . . o o o
x x . x . . o o o
x x . x o . . o o
. x x x o . . o o
. x x x o . o . o

Trabsact Sagme Diaries

A game, when moved, usually travels with its own social context. For e.g., a game from the Trok planet, in the island of Mag, is played only by children with lemur-like and duck-like animals. Some centuries ago, the game went to a neighbor island, Dag, and, even if the rules changed a bit, the ducks and lemurs are also thrown by the Dag children. [T.Sagme, Travels]

PROGRESSIVE FENCES

Cul-de-sac with L-shaped walls allowed.
Walls may be placed along edges, but not beyond them.
Win by crossing over the target edge.

The turns are progressively 1 2 2 3 4 4 5 6 6... moves, with a move being
one orthogonal step by the player's stone, or one length of 2-wall placement.
A player may distribute his available moves as he pleases (so placing a wall
costs two moves), subject to not being permitted to completely wall off
his opponent from his target.

Sample game (notation: Xy* means that a wall was placed at coordinate Xy with a certain shape given by symbol *. If * is 1,2,3 or 4 it means a L-shaped wall on the 1st, 2nd, 3rd or 4th quadrants; if * is - means a horizontal wall with center Xy; and if * is | means a vertical wall with center Xy):
