Here's my version of backgammon with one die.
DUODECAGAMMON
=============
Duodecagammon is backgammon played with one duodecahedronic die
instead of two cubic dice. This duodecahedron-shaped die has twelve
faces, all regular pentagons, numbered 1 to 12. For whatever number
is rolled, the player may choose any combination of two numbers from
one to six that add up to that number. This allows the player more
choice than in regular backgammon.
Some numbers allow two combinations: 12, 10, 5, 4, 3. Numbers in
the middle range allow three combos: 9, 8, 7, 6. The numbers 11, 2,
and 1 are, as the English would say, hard cheese.
"Doubles," as in regular backgammon, aren't allowed. That is,
playing one number four times (in actuality, a quadruple) isn't
allowed. Instead, "triples" are allowed; in a triple all components
are the same. Thus 3 can be 1+1+1, 6 can be 2+2+2, 9 can be 3+3+3,
and 12 can be 4+4+4.
The complete list of allowable "dice rolls" is as follows:
NUMBER OF
ROLL COMBOS POSSIBLE COMBINATIONS
==== ========= =====================
12 2 6+6, 4+4+4
11 1 6+5
10 2 6+4, 5+5
9 3 6+3, 5+4, 3+3+3
8 3 6+2, 5+3, 4+4
7 3 6+1, 5+2, 4+3
6 3 5+1, 4+2, 2+2+2
5 2 4+1, 3+2
4 2 3+1, 2+2
3 2 2+1, 1+1+1
2 1 1+1
1 1 1 alone
Neither zero nor numbers larger than six can be used. (Why?
Because they're not on regular cubic dice. The only number
combinations allowed are those that could be rolled with regular
dice.)
Since all triples are in the 1 to 4 range, this system eliminates
the "big doubles" phenomenon (such as double sixes or fives) and cuts
down on the "medium doubles."
Duodecagammon was invented by David Moeser of Cincinnati, Ohio, on
April 18, 1999. Note: 12-sided dice can be found in gaming stores in
all major cities. (And this note for flamers: "dodecahedron" is the
more commonly-found form of the word. I know that but chose not to
use it.)
