What is the ruling on programming an electronic offensive and defensive card game from which no money is earned?

"The ruling on electronic games and their regulations has been previously clarified. The judgment on a specific game requires a complete understanding of it. The described nature of the game (playing cards that attack and defend, with loss occurring at a certain damage threshold) does not necessitate its prohibition. Therefore, there is no harm in programming it if it is free from শর'ī prohibitions."
