>Do any chess games support these modes or is these possible to play today?
Chess.com currently supports most of the modes in the list - except, I think, semi-torpedo, no-castling (10), and pawn-back. Which, to me, are the least exciting mods anyway.
I found pawn-back to be the most interesting just from the changes to existing chess logic. Pawn-back resulted in the most change in piece-value from classical and during simulations were used 100% of the time.
