Persian Chess design, board, rules and variants are copyrighted material. Redistribution or reproduction of any part of it, or creating derivative work from the engine or sub-variants, or create and publish a new sub-variant on Persian Chess 9×9 Citadel board, or run a commercial project to (re)produce Persian Chess as a computer program or as a physical board representation, requires permission from the inventor/author. Such permission will be given on almost 100% of cases.
It is however still possible that a permission request is rejected, only if author suspects that his work would be misinterpreted or misused to spread aggression, racism, fascism, antisemitism or any other religious discrimination or hate, which is very unlikely because of the nature of a chess game.

This game, like other well designed and recognized chess variants, is inspired by a research and study of many other board and game designs, specifically mentioned in the “design inspiration and history” section.

Persian Chess is a chess variant that is played on a 9×9 board (11×11 including the Citadel squares) and an on-board Center square which is in total 85 active squares. Disregarding the alphabetical notations; the board is abstractly shown in the following diagram:

For playing Persian Chess, you don’t need to have any permission or to be familiar with the Persian language, culture, history, poetry or art. Just willing to play a reasonably well designed chess variant would be more than sufficient.
Have a good game.
