Dominoes v1.0
by Mike Perry, March 22, 1998
Introduction
Everyone knows about the game of Dominoes. There are so many
variations, from the simple "play until you're out" up to the game of
"42", which involves bidding, and lots of other weird silliness.
This is an implementation of my favourite, which I've recently
learned derives from a game called "Muggins". Basically, the idea is
to score as many points as possible by making smart plays, and/or running
out of tiles before your opponent. The key to this game is that points are
always gained in multiples of 5. If a play brings the total of the
playing field to a number that is divisible by 5, the player gets the
total added to his/her score. When a player goes out, he scores the total
of all the pips his opponent has remaining - rounded to the nearest multiple of 5.
Simple, right?
How to Play
Tiles are dealt out to create initial player hands. Remaining tiles
are put into the boneyard, for use later. (if playing with a double-9 set,
each hand starts with 9 tiles, if the double-6, each player gets 7 tiles).
Play always starts with the highest double. Whoever has it,
goes first and plays it. After that, the next player plays a
tile to the left or right of that domino, one side of which has to
match the double. Play alternates, each player playing on the
endpoint of one of the four chains (left/right/up/down). Note that
the top and bottom chains can't be developed until there is a tile on
the left and right chains. (Don't ask me why, it was the way I was
taught). If a player can't make a play, they have to draw tiles from
the boneyard until they can. (or until there are no tiles left in the
boneyard).
To play a domino, just select it, and click in the general area you
wish to play it. To draw another tile, click on the draw pile, or use
"Draw Tile" from the game menu. (As long as there are tiles left, you
can draw as often as you wish, you don't have to wait until you have
no plays) If you have no moves, and there are no tiles left to draw
from the boneyard, you have to pass - select "I can't go" from
the Game menu.
Scoring
Ok, bear with me, it's an easy concept, but slightly tricky to explain...
You score points if you play a domino that brings the current
"value" of the field to a multiple of 5. The "value" of the playing
field is calcuated by adding up the end value of each of the four
branches. (If the last domino in a branch is 4:3, the 3 outermost, the
value of that branch is 3.) If there is a double at the end of a
branch, it counts as twice the number (double-6 counts as 12).
The initial double is an exception, half of it's value counts for
the top branch, the other half for the bottom. It will make sense
when you play, I promise.
When a player runs out of tiles, they score the total of the
opponents tiles, rounded to the nearest multiple of 5. (e.g., if you
played your last tile, and the sum of your opponent's pips was 23, you
would get 25 points).
Score in this game is kept by marking crosses, each line of each
cross is worth 5 points, each cross therefore worth 10. A set of 5
crosses makes 50 points, you need 6 sets of crosses, or 300 points to
win.
Notes
Currently, you can only play against one computer opponent
(which is actually quite tough to beat). If I get enough positive
feedback, I'll come back and make it better, more players, sound,
different computer strategies, etc… fun things like that.
If branches get too long for to fit in the window, the branch
will be scrunched to fit, the early dominoes in the chain just won't
be drawn. All that matters is the last domino in each chain anyway.
You can only create new chains from first double, subsequent
doubles can not spawn new branches.
System Requirements
System 7.0.x or later.
needs to run on a 68020 or better.
Definitely looks better with colour, but works with B&W.
Licensing
Dominoes is Postcardware. I retain the copyright, but, copy it around
as much as you want (as long as you keep the instructions with it, and
don't modify it) - give it to your friends, family, pets, etc… Put it
on a disk and kick it around your garden, it's all good. You just
can't charge for it, or if bundling it on a CD, charge anything more
than nominal packaging costs, etc… I wrote this game for fun, if you
like it, and want to encourage me to write more free software, send me
