A game about making sacrifices!
The third game of Project GIPF. For 2 players.
Strange… A board that gets smaller and two players playing with
the same marbles... In the beginning you'll have to get used to
it, but once you do, you'll find out that there are many ways to
get the game under control. Play the right marble at the right place
at the right moment, and you'll gain the upper hand.
Components
 6 white marbles
 8 gray marbles
 10 black marbles
 49 round board pieces, called rings.
A. Aim
You must try to capture either
 3 marbles of each color,
 or 4 white marbles,
 or 5 gray marbles,
 or 6 black marbles.
The winner is the first player to achieve one of these goals.
B. Preparation
In total you have 49 rings. To play the basic game you need only 37
of them. So, you don’t need the 12 remaining rings yet. After
mastering the basic strategies, you can use 11 of them to play ZÈRTZ
on a board with 48 rings. (See point H. below: Expanded board.)
1. Take 37 rings
and assemble a hexagonal game board.

2. The 6 white,
8 grey and 10 black marbles are the “pool”. Put the pool
next to the board, so that both players can easily reach the marbles.
3. Draw lots to
determine who will go first.
C. Making a move
When it is your turn, there are two possible moves: you either place
a marble of any color on the board and then remove a ring, or you
capture one or more marbles.
Placing a marble and removing a board piece
1. When it is
your turn, you first select a marble from the pool. Next you must
place it on the board. You may select any color you wish and you may
place the marble on any vacant ring.
Important: the marbles, in the pool as well as on the board,
belong to both players (i.e. neither you, nor your opponent have your
“own” marbles to play with).
2. After you have
placed a marble on the board, you must remove a “free”
ring. “Free” means: the ring must be vacant and it must
be positioned at the edge of the board. In other words, there may
not be a marble on it and you must be able to remove it from the sides
without disturbing the position of the remaining rings.

2: only the rings with an arrow may be removed.
3. Placing a
marble and removing a ring is one turn. You must do both. However,
it may occur that you cannot remove any of the vacant rings without
disturbing the position of the other rings. In this case you must
not remove a ring (i.e. your move ends after having placed a marble).
Note: don’t stack the rings that you remove
on top of each other. It is better to use them to put your captured
marbles on. (See Captured marbles below.)
Capturing marbles
1. Capturing is
compulsory; you must do it if you can.
2. To capture
a marble, you must jump over it with another marble (i.e. as in checkers).
You may only jump over a marble on an adjacent ring. You may jump
in any direction if there is a vacant ring behind the marble that
you intend to capture.
3. The color of
the marbles is of no importance when capturing: you may jump with
any marble over any other marble, no matter the color, no matter whether
you or your opponent placed it on the board.
For example: you put a white marble on the board. A few moves later
your opponent places a grey marble next to it. There is a vacant ring
behind both marbles. You may select the option you think is most advantageous:
jumping with the white marble over the grey one or the other way around.
4. If you jump
over a marble and you have the possibility to jump over a second one,
then you must do so, no matter in which direction you make the second
(or third) jump.

3: The arrows indicate the different ways to capture.
1 > 2 and 3
1 > 2, 4 and 5
2 > 1
3 > 2 and 1 .
5. If you can
capture different numbers of marbles (e.g. in one direction 1 marble
and in another direction 2 marbles), you may freely chose which possibility
you’ll go for.
6. Capturing one
or more marbles counts as a complete move. In other words: that turn
you may not place a marble, nor may you remove a ring.
D. Isolating marbles
1. If you succeed in isolating one or more rings from the main part
of the board, you may claim the isolated rings, including the marbles
on them. Most of the times it will concern one ring, thus one marble,
but it is not limited to one. This “claiming” should be
seen as a second way of capturing marbles, but it is not compulsory.
Diagram
4: if you remove the ring indicated by the arrow, you capture the
marble on the isolated board piece.
2. You can only
capture marbles this way if there are no vacant rings in the isolated
group. So, you may claim one or more rings when you either put a marble
on the last vacant ring of an already isolated group, or remove the
ring through which a group of occupied rings gets isolated.
Note: you capture marbles this way as a result of
a move; it is not itself a move.
E. End of the game
As mentioned at the beginning of these rules: the first player to
obtain either 3 marbles of each color, or 4 white marbles, or 5 grey
marbles, or 6 black marbles wins the game.
F. Special cases
1. It may occur
that there are no more marbles in the pool before the game has ended.
In this case you must continue with your captured marbles. As with
selecting a marble from the pool, you may choose any color of your
captured marbles to play with  and this goes on until one of the
two players gets a winning set of marbles.
2. In the extreme
event (not to exclude the possibility) that all the rings would be
occupied before either of the players achieves one of the set goals,
it is the one who put a marble on the last vacant ring who wins. In
fact, he may claim all of the remaining rings, including the marbles,
for this situation is to be seen as an isolated group of occupied
rings.
3. If
it would happen that two players start repeating the same sequence
of moves, the game ends in a tie.
A bit of strategy
See diagram 5 below! Player A is 5 marbles behind, but he can win
the game from here! He puts a black marble on ring 1 and removes ring
2. By doing so, he forces Player B to jump over (and to capture) that
black marble. The fact that it is a black marble, means that Player
B hasn’t a winning combination yet. Then player A goes again:
he puts a white marble on ring 3 and removes 4. He captures the 2
white marbles on the isolated rings and wins with a set of 4 white
marbles!

G. Expanded board
ZÈRTZ was initially released with only 37 rings. That is all
you need to explore the game and to find out how challenging it is.
However, once you have become an expert player you may want to play
with more rings.
The extra rings you need to play ZÈRTZ on
a larger board were available from the beginning, but only as a
part of GIPF Set 2. This new version of ZÈRTZ contains 12
more rings than the initial version. But be careful! Playing on
an enlarged board only makes sense if you have first mastered the
basic strategies. ZÈRTZ is a fast and explosive game. If
you add extra rings too soon, you risk to turn it into a long, possibly
even boring game  and that is not the purpose!
On the other hand, once you are familiar with the
principles of making sacrifices and long sequences of forced moves,
then you will find an extra challenge in making the board larger.
For example: you can add a row 3 rings at one side of the board.
3 extra rings don’t add that much complexity, but they change
the board into an irregular hexagon and that implies that you now
have more different opening moves. You can go one step further and
play with 6 or 7 extra rings. If you want to play the tournament
version, you must add 11 rings. The more rings, the harder it is
to control the game!
Note 1: you don’t need extra
marbles; the number of marbles and the conditions to win remain
unchanged.
Note 2: the 49th ring is a spare piece. And you
may need it if you have GIPF Set 2 and want to play ZÈRTZ
with 24 extra rings.

and wins with a set of 4 white marbles!
Diagram 6
To play with 40 rings:
add rings 1.
To play with 43 rings: add rings 1 and 2.
To play with 44 rings: add rings 1 and 3.
To play with 48 rings: add all the rings.
H. Tournament rules
1. Tournaments are played on a board that consists
of at least 48 rings. (If you want to play on a board that is even
larger than 48 rings, you’ll need GIPF Set 2, which contains
12 more rings. ZÈRTZ with 24 added rings, thus on a board
with 61 rings, may well become the ultimate tournament version some
day.)
2. Handling the marbles and the rings: (a) once
you have taken a marble from the pool, you must play it (i.e. you
may not put it back and chose a marble of another color), (b) as
soon as you touch a ring with the marble you play with, you must
put it on that ring, and (c) as soon as you touch a vacant ring
at the edge of the board, you must remove that ring.
3. Capturing is compulsory, meaning that you
may force the opponent to take back his last move if he didn’t
do so. (Taking back a move includes putting back the removed ring.)
For example: you put a marble on the board and create an opportunity
for a capture. Your opponent does not capture; he takes a marble,
places it on the board and next removes a ring. You may have a look
at the new situation and either do the capturing yourself, or force
your opponent to take back his move and oblige him capture. (If
you don’t ask your opponent to take back his move and you
don’t capture either, then it is your opponent, when it is
his turn again, who may force you to take back your last move.
I. Blitz variant
This variant concerns the original “Basic Game”.
It is a short, very aggressive and unforgiving version to play ZÈRTZ.
It is played on a board with 37 rings, and with one marble less
per color. So, you only need 5 white marbles, 7 grey marbles and
9 black marbles. Now you must either capture only 2 marbles of each
color, or 3 whites, or 4 greys, or 5 blacks to win the game.
H. Have fun!
