5D Chess with Multiverse Time Travel (stylized in start case) is a 2020 chess variant video game released for Microsoft Windows, macOS, and Linux by American studio Thunkspace. Its titular mechanic, multiverse time travel, allows pieces to travel through time and between timelines in a similar way to how they move through ranks and files .
The general gameplay of 5D Chess with Multiverse Time Travel starts off similarly to a standard game of chess. As the game progresses, the game becomes increasingly complex through a series of alternate timelines that the player can take advantage of. [1] The game can be played online against other players or offline against an AI or another player sitting at the same computer. [2]
A standard game of 5D Chess begins with an ordinary chess setup, starting on White's turn. The game has the original two axes from standard chess and two additional axes of movement:
All four are considered dimensions, and pieces can move through combinations of dimensions. In this display, the vertical directions of the timeline axis are opposite for each player, but the horizontal directions of the turn axis are the same. Each point in time in each timeline is displayed as an individual board. A distance of one space corresponds to a distance of one square horizontally, one square vertically, one turn, or one timeline. Each player takes their turn by making a move or series of moves and then pressing the "Submit Moves" button. All pieces retain their movement abilities from standard chess. In addition, their movement abilities are generalized across the turn and timeline axes. [3] The moves of the pieces are as follows:
When moving, the rook, bishop, and queen must travel through a continuous series of unobstructed squares.
A player may make a move only on a board where it is their turn. A move is considered to be made on a board if the piece making the move begins and/or ends its move on that board. If a player makes a move on a board, then the resulting position is created as a new board, one half-turn to the right; the original board itself remains unchanged. The new board is on the opponent's turn. A board is outlined in the color of the player whose turn it is on that board.
A timeline consists of a series of boards in the same horizontal row. If a board is the latest board on its timeline, then the board is considered to be playable, indicated by a thick outline; otherwise, it is considered to be unplayable, indicated by a thin outline. A player may make a move only using a piece that stands on a playable board. If a piece's move occurs on a playable board, then the resulting new board is created on the same timeline.
A piece may travel through time using its movement abilities. If a player makes a move such that a piece travels to an unplayable board, then a new timeline is created in the direction of the player, downward from that player's perspective, in the vacant row closest to the originating timeline; the resulting new board is placed on the new timeline. A piece may move between timelines. When a piece travels between boards, only boards outlined in the player's color are considered; boards outlined in the opponent's color are ignored. [4] [2]
A timeline created by a player is considered to be that player's timeline. If a player, while their number of timelines is at least one greater than the opponent's number of timelines, creates a timeline, then that new timeline is considered to be inactive; if a timeline is not inactive, then it is considered to be active. If a player, while the opponent has at least one inactive timeline, creates a timeline, then the opponent's oldest inactive timeline becomes active. An active board is a playable board on an active timeline.
The present line is a large vertical bar that always aligns itself with the active board which is the furthest left along the turn axis. The present line also touches every board in the same column as that board. Every board touched by the present line is considered to be in the present. On a player's turn, they must make moves until the present line shifts to being on their opponent's turn. The player may also optionally make moves on any playable board where it is their turn. The player may undo any moves made during their turn prior to the end of that turn. The player's moves are finalized and the turn is complete when the player submits their moves.
A player is in check in a situation where it is the player's turn and, if the player were to pass their move on all active boards in the present, then the opponent would be able to capture one of the player's kings. A player cannot take their turn in a way that would allow one of their kings to be captured. If the player whose turn it is has no way to legally complete their turn, then the game ends in one of two ways:
5D Chess has many variant modes. These can alter factors such as the starting position, the board size (4×4, 5×5, 6×6, 7×7, and 8×8 are possible), the number of starting timelines, and so on. The game also has several fairy pieces, which move as follows:
When moving, the princess, unicorn, and dragon must travel through a continuous series of unobstructed squares.
The game features a puzzle mode.
Turn Zero is a variant starting with a configuration in which there is an additional board for Black a half-turn earlier in the main timeline. The variant is often used in tournament play for balancing purposes.
The game was launched on 22 July 2020 on Steam. It was developed by Conor Petersen and Thunkspace. [5] Petersen said that he had enjoyed chess variants such as three-dimensional chess and conceived of using time as an additional dimension for piece movements. He said, "From there, I tried to solve each problem or paradox I found". [6]
Kotaku reviewer Nathan Grayson called the game "remarkably elegant for what it is". [4] Arne Kaehler of ChessBase wrote that while the game ran well and is a fun chess variant, the opponent AI was not very competent. [2] A Digitally Downloaded reviewer wrote that, due to the increasing complexity of the game as turns pass, it presents a "limitless well of possibility". [7] Christopher Livingston of PC Gamer called the game "mind-bending". [8] Jacob Aron of New Scientist wrote that the game "isn't for the faint-hearted" and "is brain-meltingly hard". [9]
Grandmaster Hikaru Nakamura played the game when appearing on VENN in August 2020. [6]
A chess piece, or chessman, is a game piece that is placed on a chessboard to play the game of chess. It can be either white or black, and it can be one of six types: king, queen, rook, bishop, knight, or pawn.
Three-dimensional chess is any chess variant that replaces the two-dimensional board with a three-dimensional array of cells between which the pieces can move. In practice, this is usually achieved by boards representing different layers being laid out next to each other. Three-dimensional chess has often appeared in science fiction—the Star Trek franchise in particular—contributing to the game's familiarity.
Bughouse chess is a popular chess variant played on two chessboards by four players in teams of two. Normal chess rules apply, except that captured pieces on one board are passed on to the teammate on the other board, who then has the option of putting these pieces on their board.
A fairy chess piece, variant chess piece, unorthodox chess piece, or heterodox chess piece is a chess piece not used in conventional chess but incorporated into certain chess variants and some unorthodox chess problems, known as fairy chess. Compared to conventional pieces, fairy pieces vary mostly in the way they move, but they may also follow special rules for capturing, promotions, etc. Because of the distributed and uncoordinated nature of unorthodox chess development, the same piece can have different names, and different pieces can have the same name in various contexts.
Martian Chess is an abstract strategy game for two or four players invented by Andrew Looney in 1999. It is played with Icehouse pyramids on a chessboard. To play with a number of players other than two or four, a non-Euclidean surface can be tiled to produce a board of the required size, allowing up to six players.
Vernon Rylands Parton was an English chess enthusiast and prolific chess variant inventor, his most renowned variants being Alice chess and Racing Kings. Many of Parton's variants were inspired by the fictional characters and stories in the works of Lewis Carroll. Parton's formal education background, like Lewis Carroll's, was in mathematics. Parton's interests were wide and he was a great believer in Esperanto.
Kriegspiel is a chess variant invented by Henry Michael Temple in 1899 and based upon the original Kriegsspiel developed by Georg von Reiswitz in 1812. In this game, each player can see their own pieces but not those of their opponent. For this reason, it is necessary to have a third person act as an umpire, with full information about the progress of the game. Players attempt to move on their turns, and the umpire declares their attempts 'legal' or 'illegal'. If the move is illegal, the player tries again; if it is legal, that move stands. Each player is given information about checks and captures. They may also ask the umpire if there are any legal captures with a pawn. Since the position of the opponent's pieces is unknown, Kriegspiel is a game of imperfect information.
Yari shogi is a modern variant of shogi ; however, it is not Japanese. It was invented in 1981 by Christian Freeling of the Netherlands. This game accentuates shogi’s intrinsically forward range of direction by giving most of the pieces the ability to move any number of free squares orthogonally forward like a shogi lance. The opposite is true of promoted pieces which can move backward with the same power.
Judkins shogi is a modern variant of shogi, however it is not Japanese. Credit for its invention has been given to Paul Judkins of Norwich, UK, prior to April 1998.
Heian shōgi is a predecessor of modern shogi. Some form of the game of Chaturanga, the ancestor of both chess and shogi, reached Japan by the 9th century, if not earlier, but the earliest surviving Japanese description of the rules dates from the early 12th century. Unfortunately, this description does not give enough information to actually play the game, but this has not stopped people from attempting to reconstruct this early form of shogi.
Hexagonal chess is a group of chess variants played on boards composed of hexagon cells. The best known is Gliński's variant, played on a symmetric 91-cell hexagonal board.
Minichess is a family of chess variants played with regular chess pieces and standard rules, but on a smaller board. The motivation for these variants is to make the game simpler and shorter than standard chess. The first chess-like game implemented on a computer was the 6×6 chess variant Los Alamos chess. The low memory capacity of early computers meant that a reduced board size and a smaller number of pieces were required for the game to be implementable on a computer.
Three-player chess is a family of chess variants specially designed for three players. Many variations of three-player chess have been devised. They usually use a non-standard board, for example, a hexagonal or three-sided board that connects the center cells in a special way. The three armies are differentiated usually by color, with White, Black, and Red serving as the most common color combination.
Senterej, also known as Ethiopian chess, is a regional chess variant, the form of chess traditionally played in Ethiopia and Eritrea. It was the last popular survival of shatranj. According to Richard Pankhurst, the game became extinct sometime after the Italian invasion of Ethiopia in the 1930s. A distinctive feature of Senterej is the opening phase – players make as many moves as they like without regard for how many moves the opponent has made; this continues until the first capture is made. Memorization of opening lines is therefore not a feature of the game.
The following outline is provided as an overview of and topical guide to chess:
Rhombic chess is a chess variant for two players created by Tony Paletta in 1980. The gameboard has an overall hexagonal shape and comprises 72 rhombi in three alternating colors. Each player commands a full set of standard chess pieces.
Chesquerque is a chess variant invented by George R. Dekle Sr. in 1986. The game is played on a board composed of four Alquerque boards combined into a square. Like Alquerque, pieces are positioned on points of intersection and make their moves along marked lines ; as such, the board comprises a 9×9 grid with 81 positions (points) that pieces can move to.
Three-man chess is a chess variant for three players invented by George R. Dekle Sr. in 1984. The game is played on a hexagonal board comprising 96 quadrilateral cells. Each player controls a standard army of chess pieces.
Portal chess is a chess variant which uses at least two fairy pieces called portals. These pieces can be easily added by using poker chips, coins or other suitably sized objects. The game seeks to incorporate portals to allow pieces to teleport around the board. Apart from the portals and their ruleset, the game often plays like ordinary chess, including the en passant capture, castling, and promotion.
