K=4*Chess King - moves like a 4*Chess Queen, only one square/mini-board at a time (no castling) Q=4*Chess Queen - moves like a 4*Chess Bishop or 4*Chess Rook, or a 4*Chess Unicorn, or a 4*Chess Balloon R=4*Chess Rook - changes 1 coordinate as it moves, like a rook U=4*Chess Unicorn - moves like a bishop except changes 3 coordinates as it moves (standard 3D fairy chess piece) ī=4*Chess Bishop - changes 2 coordinates as it moves, like a bishop (does not change square colour even if moving to another mini-board) In 4*Chess, some 3 and 4 dimensional moving pieces are introduced, and all the pieces may possibly move between the mini-boards when performing a move (note that 'coordinate' in these instructions refers to the rank or file of a square on a mini-board, or refers to the row or column number of a mini-board):ĭ=4*Chess Balloon (I'd nickname it Dirigible) - moves like a bishop except changes 4 coordinates as it moves & stays on same square colour (standard 4D fairy chess piece) A Game Courier preset for play is available. Note that some links are provided in the Notes section, for further reference. I played a game of it with a friend, and it didn't take too long after a blunder, as we knew a 4*Chess King and 4*Chess Queen vs. It's based on a BASIC computer program I made for it in the 1980's, which took up less than 16K.
Using a computer program for it, a player could check if he is making a legal move, and whether it is mate or stalemate, for example. A 16x16 board with appropriate spacing could be used even on a coffee table it would be about the size of a Scrabble board (15x15 for that). The game is played using sixteen 4x4 (2D) mini-boards that are arranged in four columns and four rows. 4*Chess (four dimensional chess) Here's a 4 dimensional chess game that can be played as if on a 2D plane. This page is written by the game's inventor, Kevin Pacey. Let's solve some examples based on this concept.Check out Opulent Chess, our featured variant for July, 2023. Total number of squares in a m*n board= ∑ (m*n) m, n varying from 1 to m,n respectively.įor example, number of squares in 2*3 board = 2*3+1*2=8įor your practice, you can calculate the number of squares and rectangles in a 6*7 board. (A rectangle can be formed by selecting 2 lines from m+1 lines and 2 lines from n+1 lines) For example, number of rectangles in a 2*3 board will be =18
Total number of rectangles in a m*n board Let us see how we can get a generalized formula to calculate the number of squares and rectangles in an m*n chessboard. Having a standard formula to calculate the number of squares and rectangles in an m*n chessboard will simplify the problem. In this case, the above-derived formulas won't work. Also, we can be asked to calculate the number of squares and rectangles in a m*n board. Note: The squares will also be included in counting rectangles.Ĭalculating it every time is cumbersome. Total number of rectangles in a n*n chessboard will be We can generalize this in the following way: We can approach the problem in the following way:
