Hypergammon
Hypergammon is a variant of backgammon.
Rule variations
[edit | edit source]Each player begins with three pieces, rather than fifteen. At the start of the game, each player begins with one piece on each of the three most distant points of the board (the 22-point, the 23-point and the 24-point).[1]
Hypergammon is often played using the Jacoby Rule, which is also used in backgammon money games. Under this rule, gammons and backgammons will not count extra until the cube has been doubled.[2]
Gameplay
[edit | edit source]As a consequence of the reduced number of pieces, many people believe that hypergammon relies more heavily on luck than backgammon. The difficulty of getting two pieces on the same point means that both players nearly always have blots on the board. The combination of the fact that bearing off can be completed with a single lucky roll of doubles, and that it is nearly impossible to protect blots from being sent to the bar, results in gammons being scored much more often than in backgammon. This also means the lead in a game can swing very quickly.
In fact, for most players, the skill-to-luck ratio (or, more precisely, the error-to-luck ratio) is much higher in hypergammon than in backgammon, which means that a skillful player can achieve a statistically significant lead much more quickly in hypergammon than in backgammon. The best moves in hypergammon (especially doubling decisions) are often subtle and less easily conceptualized than those of backgammon.
Hypergammon has been 'solved', in the sense that computers can now play perfect hypergammon.[3] Nevertheless, it is still a very challenging game for human players. The development of heuristics for expert play is very much an open topic.
In the early 1990s Hugh Sconyers solved Hyper Backgammon using a computer. There are over 32,000,000 possible positions when you include the double cube. In addition, Sconyers solved 1, 2 and 4 checker backgammon, which have similar starting positions.
Popularity
[edit | edit source]Coming out in 1991, Hypergammon was and is known to be part of an online computer application. It can be played in real life as a board game too, but even now, people competitively play the game and try what they can to keep their rank one title. Marc Olsen is known as a 'grandmaster' Hypergammon player, and has written about strategies for playing the backgammon variant.
Competition
[edit | edit source]Hyper Backgammon has been included within the Mind Sports Olympiad program, for the first time in the in-person event in London 2023, after holding it in the online versions in 2020 and 2021 and the online Grand Prix.[4]
