I don't think I was clear enough. For example, I would like to be able to disable swap for games like Hex in the graphical interface (Options menu).
Thank you for your consideration.
Yes Quentin to make the swap rule to be enable or not in the GUI feature, you have to use the options mechanism in the description of the game. I added that to our Hex.lud (see attachment). You can load it with Ludii (Load Game from File) and then in the options menu you will be able to disable the swap rule if you want. I will let that option for the next release in Hex to let the possibility to anyone to disable it if wished.
