Smart Summary: Zerogammon is a new version of the classic Backgammon game. It features a game board with 20 points instead of the usual 24 and special dice that show numbers from zero to five. Players roll these unique dice to decide how to move their pieces, which adds more options for strategy. Rolling a zero can slow down a player's progress, while rolling double zeros means they lose their turn. This fresh approach makes the game more exciting and encourages players to think differently about their moves. 🚀 TL;DR
An enhanced version of the Backgammon game (“Zerogammon”) with a novel method of play. The improvement features a modified game board with 20 points instead of the traditional 24, along with a pair of uniquely designed dice, each having six faces with values ranging from zero to five. These modifications alter the traditional rules, allowing for greater variety in movement and strategy. Players take turns rolling the specialized dice, determining marker movement based on the dice values. This unique arrangement provides the possibility of slowing a player's advancement if a zero is rolled or forfeiting their turn if double zeros are rolled. This method introduces an additional tactical layer, encouraging new strategic approaches to gameplay. The invention's unique combination of dice and board design offers an innovative variation in the traditional Backgammon experience.

This application claims the benefit of U.S. Provisional Application No. 63/648,390, filed May 16, 2024.
Backgammon, a game with roots dating back over 5,000 years, is played by two players on a gameboard. Players maneuver their checkers around the board based on the roll of two dice, aiming to move all their checkers through twenty-four landing points into their home board and subsequently bear them off to win. Beyond entertainment, Backgammon offers cognitive benefits by promoting strategic thinking, decision-making, and numeracy skills. It fosters social interaction, providing a platform for friendly competition. Moreover, it serves as a stress reliever, aids memory retention, and teaches patience and resilience.
Enhancing the Backgammon experience entails developing an improved game with a greater range of moves. Existing proposals have limitations, prompting the need for a novel game utilizing unique dice markings to provide an engaging and intellectually stimulating player experience. The Zerogammon method of play allows for a more interesting and thought-provoking player experience. Through newly devised rules tailored for the enhanced Backgammon game and its gameplay, the present disclosure aims to challenge players' mental acuity, putting their cognitive abilities to the test.
The present disclosure proposes a new and improved version of the classic game called Zerogammon game, along with a method of playing utilizing a six-sided dice featuring values ranging from zero to five. This addition of a zero face on the dice introduces the possibility of preventing a player from moving on a given roll, particularly when rolling the zero, effectively reducing the influence of luck and emphasizing strategic gameplay. The present disclosure includes various components, with the dice being a key element. The game is played on a Backgammon board comprising twenty narrow triangles called points, divided into four quadrants for each player's “inner table” and “outer table”.
Through the introduction of the zero-dice, the present disclosure not only enhances the Backgammon game but also opens possibilities for new ways of playing other existing games that require traditional dice. This innovation provides several advantages, including a unique gaming experience, increased complexity and strategy, and suitability for players of all ages. These and other advantages of one or more aspects will become apparent from consideration of the ensuing description and accompanying drawings. Although these descriptions contain much specificity, these should not be construed as limiting the scope of the embodiments but as merely providing illustrations of some of several embodiments. For example, the dice may be constructed from plastic in one embodiment and with porcelain or other suitable material for playing dice in another. Thus, the scope of the embodiments should be determined by the claims that are appended and their legal equivalents, rather than by the examples given.
In this regard, while the present disclosure provides specificity (as will be discussed in the description of the drawings/images below), it should not be limited to certain embodiments, for variations and modifications can be made within the appended claims. The embodiments aim to address the needs of players seeking innovation while retaining the essence of traditional Backgammon.

FIG. 2. A plain view of the initial game board with game marker setup.
FIG. 3. Shows the markings on all six sides of the unique zero dice.
FIG. 4. Shows an isometric view of the unique six-sided, zero dice.
The improved Backgammon game, as depicted in FIG. 1, showcases the game board at the beginning of a Zerogammon match. The points on the board in FIG. 1 are identified from the perspective of the “brighter” player, serving the purpose of illustration. Consequently, the player with the darker markers would have their numbers arranged oppositely. Initially, the markers are positioned as follows: Two on the twenty-point, five on the brighter player's fifteen-point, three on the seven-point, and five on the five-point. The arrangement of markers for one player mirrors that of their opponent.
In FIG. 2, we observe the starting positions of all markers on the backgammon board as the game commences. The board is divided into the “home” board and the “outer” boards, which are separated by the bar. The first player's “inner table” or “home” spans the first five points (1-5), with points numbered sequentially from one to twenty, starting from the point farthest to the right of the first player and proceeding clockwise around the board. The “outer board” for the first player encompasses points six through ten (6-10). Conversely, the opponent or second player's home board comprises points sixteen through twenty (16-20), while their “outer board” encompasses the quadrant with points eleven through fifteen (11-15).
FIG. 2 also illustrates the direction in which both the light and dark colored markers move throughout the game: counterclockwise around the backgammon board for the bright markers, and clockwise for the dark markers.
As per FIG. 2, gameplay in Zerogammon closely resembles that of traditional Backgammon, albeit with several adjustments to accommodate the introduction of the zero dice. Like western Backgammon, the primary objective remains to move your markers based on the numbers rolled on the dice. Players always advance their markers to a lower numbered point on the board. Initially, each player aims to move all their markers into their respective “home” board, after which they can commence bearing off individual markers. The first player to successfully bear off all their markers wins the game.
During the process of moving markers into their home board, players face the risk of having their markers hit and sent to the bar by their opponent. A point occupied by only one marker of a player is known as a blot. If an opponent lands on a blot, it is hit, and the player's marker is placed on the bar while the opponent replaces it with their own.
Whenever a player has one or more hit markers on the bar, their priority is to enter those markers into the opposing home board. This can be achieved by moving the markers to an open point, not occupied by two or more opposing markers, corresponding to one of the numbers rolled on the dice.
In the event of rolling doubles, the player plays each number shown on the dice twice. For instance, if a player rolls double fives, they can utilize four fives and move any legal combination of markers to fulfill this requirement.
Moreover, FIG. 3. illustrates where zero indicia may be located with respect to traditional six-sided dice markings (one through six).
Furthermore, FIG. 4 illustrates the isometric view of the unique, six-sided, zero dice. In reference to FIG. 4, the inclusion of a six-sided dice with a zero on at least one side significantly alters the probability of a player rolling dice positions that prevent their progress on the board. With this modification, there's a notable decrease in the potential moves available to advance in the game. Rolling a dice with values one through five (1-5) allows the player to move forward, while rolling a zero restricts their progress. This introduction of the null set zero effectively reduces the player's movement possibilities by 16%.
Hence, when the yield results containing zero value, it impedes game progression, either by slowing down the player's advancement or leaving the game unchanged. If a player rolls two zeros, they forfeit their turn, which is not a possibility in traditional Backgammon games like Western Backgammon. Normally, in those games, a player may not move if there are no legal moves possible after rolling the dice. The incorporation of the zero dice necessitates adjustments to the traditional backgammon setup to accommodate the structure, marker navigation, and strategic elements of the game. As a result, the Zerogammon board will have twenty points instead of the traditional twenty-four, affecting the game's pacing.
