While, we believe the game of chess shouldn’t be changed as one shouldn’t mess with simplicity, we still find multidimensional chess games and different chess variants interesting. While they aren’t technically considered Chess in the traditional since, they still should have an established and organized method of information for ratings and events. That is why under IOCS, this league also exists to support multidimensional and other chess variant players.
Orthodox Variants
The back ranks of the chess board has different starting positions. Outside of that, the rules are Orthodox.
This game is played on a hexagonal 61 cell chess board with extra rook, knight and pawn.
This is a variant on a 9×8 chess board where each side ends up getting an additional queen.
This is a variant featuring a specially designed chess board that is hexagonal shape with rhombic cells. The cells feature three colors, and special rules apply to this variant on the basis of its geometry.
This is played on a hexagonal chess board, and the most common variant has three colors as well as three bishops for each side.
Called mini chess, this chess variant is played without bishops, and was one of the first chess variants played by a computer. Also, it has special rules in regards to pawns and no castling.
Non-Orthodox Variants
Not considered fully orthodox given no castling and slight changes of rules for the circular board.
Chess variant primarily based off of the concept of “friendly knights” gaining the power of a knight. Kings and knights can’t relay knight moves.
Pieces that capture changes colors excluding the King. Many different proofs and technicalities go into this that varies moves from orthodox and non.
Different than Chess Cubic, this variant relies on four faced cubic chess pieces and slight differences in rules.
Portal Chess variants apply less traditional rules in which at least two pieces can act as portals. This is usually determined through coins or chips.
Newer, but emerging chess variant where pieces move based off of superposition.
Multidimensional Chess Variants
Three dimensional chess utilizes multiple chess boards to represent vector space, and sometimes applies special rules as a result.
4D Chess is actually quite more complicated and adds another dimensional layer for the game play creating tesseract cubes.
The newer 5D chess variant has branching timelines and complex rules with a series of boards. It is a growing trend in the chess community made by an indie developer.
There is not yet fully accepted concepts for 7D chess. Most likely 7D chess would by 3D chess with added time constraints and rules, or 4D chess with added dimensions.
This chess variant an entirely unorthodox four sided cubic chess board design (that is magnetic) and range movement rules centered around its design.
3D inspired Chess variant played on Star Trek with slightly different rules given its unorthodox design. Also, rules apply to attack vectors.
Elo System:

The elo-based rating system we want to apply will be applied in similar ways as well as similar scales to traditional chess, and known orthodox variants that collect scores. This will be done for the sake of simplicity as well as collecting easy to track metrics for both in-game analysis and player rankings.
