Modding Possibilities

Do I understand correctly that Elemental Dungeon Roulette is essentially built on real roulette algorithms? Would it be possible to modify it or add custom mini-games that enhance the excitement and gambling aspect of the game? For example, I have explored various types of gambling games here, and I think I could try implementing some of these mechanics as a mod. However, I am unsure what software the game supports for such modifications or which version would be best suited for this. Could anyone provide insights on the game's modding capabilities and compatibility with third-party tools?
