Noppa Dice Roller is a flexible dice rolling app for tabletop RPGs and tactical games.

Roll normal dice using notation such as 3d6+5, or different dice like:
- Multiple rolls: 4x 3d6 rolls 3d6 four separate times
- Zero-based dice: z10 gives values 0–9
- Keep highest: 5g6 rolls 5d6 and keeps the largest
- Keep highest with duplicates bonus: 5G6 like above but duplicates add +1
- Zero-mean dice: 4f1 rolls four dice each giving -1, 0, or 1
- Exploding dice: e6 rolls again on a 6

Modifiers let you add named bonuses (e.g. Skill, Strength) that can be toggled on or off. Tag modifiers to filter which ones apply to a given roll.

Save and load modifier sets and roll history for defaults and different game systems. Customize conditional ("exploding") dice rules using configuration files.
