GO VS KAMISADO

Go is an abstract strategy board game for two players in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia. The playing pieces are called stones. One player uses the white stones and the other, black. The players take turns placing the stones on the vacant intersections (points) of a board. Once placed on the board, stones may not be moved, but stones are removed from the board if the stone (or group of stones) is surrounded by opposing stones on all orthogonally-adjacent points, in which case the stone is captured. The game proceeds until neither player wishes to make another move. When a game concludes, the winner is determined by counting each player's surrounded territory along with captured stones and komi (points added to the score of the player with the white stones as compensation for playing second). Games may also be terminated by resignation. The standard Go board has a 19×19 grid of lines, containing 361 points. Beginners often play on smaller 9×9 and 13×13 boards, and archaeological evidence shows that the game was played in earlier centuries on a board with a 17×17 grid. However, boards with a 19×19 grid had become standard by the time the game reached Korea in the 5th century CE and Japan in the 7th century CE. Go was considered one of the four essential arts of the cultured aristocratic Chinese scholars in antiquity. The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan (c. 4th century BCE). Despite its relatively simple rules, Go is extremely complex. Compared to chess, Go has both a larger board with more scope for play and longer games and, on average, many more alternatives to consider per move. The number of legal board positions in Go has been calculated to be approximately 2.1 × 10170, which is vastly greater than the number of atoms in the known, observable universe, estimated to be about 1 × 1080.

Kamisado is an abstract strategy board game for two players that's played on an 8x8 multicoloured board. Each player controls a set of eight octagonal dragon tower pieces. Each player's set of dragon towers contains a tower to match each of the colours that appear on the squares of the board (i.e., a brown tower, a green tower, etc.). One player's towers have gold dragons mounted on the top, while the other player's towers are topped with black dragons. In an interview, designer Peter Burley said that the design of Kamisado dated back to a chance observation in a men's room in the 1970s. "I noticed that the floor had an interesting pattern of small colored tiles", he said. "I mentally made a note that this could possibly be used as a basis for a board game – this is something that I do quite a lot, whenever I see something a bit different. It must have made a deep impression on this occasion, however, because that night I had a vivid dream involving this tile pattern, and somehow the notion of 'whatever colour you land on, your opponent must move a piece that matches this'. I guess my subconscious mind had been working on this and sorted it out while I was asleep." The players’ towers start the game on the row nearest to them. The players take turns moving one tower any number of spaces in a straight line, either directly forwards or diagonally forwards, but not into or through a square already containing another dragon tower. The player with the black dragons moves first and may choose any tower. From this point onwards, each player must move the dragon tower that matches the colour of the square that the opponent's last move finished on. The object of the game is to reach your opponent's Home Row with one of your dragon towers. The first player to achieve this goal is the winner of the round. Games may be played as single rounds, or as more advanced ‘Match’ formats. Matches are played up to 3 points (Standard Match), 7 points (Long Match) or 15 points (Marathon Match). During a match, each time a round is won, a special ‘Sumo Ring’ is added to the dragon tower that has fought its way through to the opponent's Home Row. The sumo rings provide the scoring system for the game, and also endow special powers to the dragon towers that carry them. These towers are known as Sumo towers and have the ability to push opponent's towers back one space, by using a move known as a ‘Sumo Push’.
