I made a web page where you can simulate a complex dice roll sequence with conditionals (e.g. re-roll when roll is a 1) using a Python-like syntax. (Click the "Toggle Syntax" button to view examples)
It needs a second to load because it has to load a Python interpreter in the background (I'm not good at web development) but once that's done, it works really well.
I now have it in a state where I'm happy with it and can check all the dice sequences I need for balancing etc.
Maybe some of you could use it too.
There's also just the Python version available to run locally here
Everything is GPLv3, enjoy!
