Mathematichess is a new chess variant created for both chess lovers and mathematicians. It is played on a normal chess board and involves unique rules that incorporate mathematical concepts.
This game is a combination of Chess, Go, Rummy, and Maths. The objective of the game is to control the empty squares that give value points to the owner. The value of a square depends on the number and type of pieces surrounding it.
The initial setup is an empty board.
Each player has 5 Kings, 5 Queens, 5 Rooks, 5 Bishops, 5 Knights, and 5 Pawns, with values ranging from 10 to 1.
The game has two stages:
In the first stage players take turns placing their pieces anywhere on the board until all pieces are on the board. In the second stage players battle for controlling the empty squares. Each player has 30 pieces. When all pieces are on the board four empty squares should remain. The empty squares are the focus of the game.
Each piece has a certain numerical value:
The King has a value of 10. The Queen has a value of 9. The Rook has a value of 5. The Knight has a value of 4. The Bishop has a value of 3. The Pawn has a value of 1. Pieces have to move differently from classical chess due to the crowded board.
All piece movements are only allowed towards an empty square.
Pawns move by jumping over a piece (of the same or different color) in any direction. They cannot jump over a Royal figure: King or Queen. Bishops move one square diagonally. Knights move like in the classical chess. Rooks move one square orthogonally. Queens move one square in any direction. Kings move one square in any direction. Kings and Queens can also push a non Royal piece, of the same or different color, into an empty square while moving. The pushed piece ends in the previously empty square, the royal in the pushed piece's previous square, and the royal's previous square is now empty. The Queen is also allowed to move or push a piece across/along a joined territory more than one square per turn if that is possible.
General rules There is no castling, no en passant, no promotions, no check, and no check mate. Also, there is no capturing of pieces. The battle is around the empty squares. Each empty square represents a territory whose value is given by the value of the pieces (Settlers) around it. The objective of the game is to control a majority of territory points.
Each territory in the center of the board can have 8 Settlers, territories on a side 5 Settlers, and a corner territory just 3 Settlers. Players are allowed to join territories (two or more empty squares) if they can control them; they must be orthogonally connected to count as a single territory.
A player may pass their turn. If a player passes two turns in a row, the game ends (so their opponent will have had the last move). The game also ends when a player has no more legal moves, or by agreement between the two players if a certain territory configuration has been reached.
In order to avoid repetition, players are not allowed to move the same piece twice in a row to the same squares.
Territory valuation Base value
The value of a territory is calculated as following:
Pieces controlling the sides have their value doubled. Pieces controlling the corners retain their original value. The values of all pieces controlling a territory are added together giving the overall value of that territory. The player contributing the majority of the points of a territory wins all the points of that territory. In case of equal contributions, the players split the points.
Bonus points
Additional points are given to players with multiple Settlers of the same kind controlling a territory. For a territory in the center or side of the board, the bonus requires at least three settlers of the same type (three pawns, or three bishops, etc.). For territories on a corner of the board, bonus points are given for having at least two settlers of the same kind. In either case, the bonus points are calculated by adding the value of these like pieces, and then their value gets tripled, and added to the overall value of that territory.
If a territory is also entirely composed of pieces of the same color, the overall value of that territory is doubled.
The quality and position of the Settlers is more important than the numerical advantage.
Players may also decide the winning conditions and the value of the additional (bonus) points for different pieces combinations in their own territories. For examples, taking inspiration from Poker, players may agree to create "Four of a Kind" or "Full House" combinations for their controlled territories, with additional bonus points for each variant.
A game can also end after a certain number of moves per player.
