- PHALANX - A straight line of 2 or
more adjacent friendly soldiers (never Kings).
- Soldier - moves diagonally forward
to an adjacent empty cell. If it reaches last row, it promotes to a King
- King - slides diagonally a straight
line of empty cells.
- Phalanx - moves diagonally forward
to an empty cell. All phalanx' soldiers move in the same
direction. The player may choose to move only part of the phalanx,
and so, splitting it.
- In the case of a phalanx reaches the last
row, the front soldier promotes to King and the others remain a
CAPTURE - Capture is mandatory.
The player can only move a piece, if it has no captures
- Phalanx captures precedes single
piece's captures (either Soldier or King).
- If there are more than one capture
of the same type,
the player must choose the capture that maximizes number
of captured pieces (a King counts as one piece).
To capture, a phalanx can move
forward or backward (always diagonally). If the cell in front of
a phalanx is empty and the cell beyond is occupied by an
opponent's piece, the phalanx advances to that empty cell and
- that piece if it is a King or a
soldier which not belongs to an opposing phalanx on the same
- an entire phalanx, if that piece
is the head of an opposing phalanx on the same line.
A single piece may capture both forward and backward and may
change direction as often as is required under the condition of
- A soldier that is the head of a
phalanx in a particular direction can never capture as a
piece in that direction (since phalanx capture comes first),
but it may capture on a perpendicular direction. The soldier
is then called isolated in the latter direction.
- A soldier can only start a
capture in a direction in which it is isolated. Once the
capture starts, the soldier remains isolated by definition for
the rest of the turn.
- If a soldier is isolated on a
particular line, and next to it on that line is a empty cell
followed by a cell occupied by an opponent's piece, then the
soldier captures the piece by making a one step approach onto
the empty cell (only that soldier is captured, not an entire
phalanx, if any). If it can proceed in a similar way in
another direction (including 180o turns), it must
do so, taking care beforehand to establish the route that
brings the maximum number of captured pieces. Kings count as
- A King captures at any distance,
an opponent's piece, by sliding onto the last empty cell
before it. If it can proceed in a similar way in another
direction (including 180o turns), it must do so,
taking care beforehand to establish the route that brings
maximum number of captured pieces.
- Only after a multiple capture
has taken its complete course, the captured pieces are removed
- In the course of a multiple
capture a piece may visit the same cell more than once, but it
may not capture the same piece more than once.
- GOAL - Wins the player
that makes the last move (either by capturing all enemy stones, or by
blocking all the remaining pieces).
- The game ends in a draw after a
3-fold board repetition.
to move. He chooses the phalanx move f6e5d4-c3. White only has two valid
moves left (i3-j4 or e1-d2).
After e1-d2, black move
something like j8-i7, then i3-j4, j6-k5, j4-i5 (only move) and k7-j6
capturing i5. Black wins by stalemating White.
From the author: I'd like to introduce two
terms, tempo and pace. The concept of phalanx movement gives Bushka an unusual
flexibility in both. Both concepts tend to lose much of their meaning once kings
come into play. Pace is calculated by giving one point to each man on the bottom
rank, two points to each man on the second rank, and so on. It does not depend
on mobility or the opponent's position (though the difference in pace of course
does). Tempo is more difficult to calculate. Roughly speaking it is the number
of moves a player has available. In the opening and middle game, it is usually
the number of moves a player has available behind a frontline. Since tempo
concerns a number of moves, it may (and usually will) be affected by the
opponent's moves. [...] Making
much pace is good in an open game: you go for the back rank. Making
little pace is good in a closed game: you need tempo-moves behind the
front-line. As far as anticipating the nature
of the game goes, the decision whether to keep men back is a strategic one.
The capture mechanism is inspired on Fanorona.
