Ssangnyuk (or Ssang-yuk) is a game for two players using dice; it is most commonly played in winter. It has a game board, 30 horses and 2 dice.[1]: 79–81 It is also called ssangnyuk (same spelling and sound but different hanja: 雙陸), aksak (hangul: 악삭, hanja: 握槊), sangnyuk (상륙, 象陸), and ssang-yuk (상육, 象陸).
The game is similar in structure and play to those of the Tables family of games, a genre that includes Backgammon.[2]
The game board doesn't have any required size, but on average it is 80 cm (31 in) long and 40 cm (16 in) wide. A die is about 1 cm³ and is made from ivory or bone. Tiger bone is preferred.
Movement is similar to backgammon according to the throw of the dice; typically two pieces are moved when doubles are thrown, and doubles do not entitle the player to another turn.[1]: 80
