Bring Drama to the Numbers with Dice Rolls
In TRPGs and board games, dice are not just random number generators, but the "wheels of fate" that influence the story. This tool supports your game sessions with a smooth operating feel and high visibility.
Usage Ideas
- TRPG Session Progression: Comprehensive coverage of major dice from D4 to D100. One-tap completion for multi-dice rolls like "3D6" or "1D100".
- Substitute for Board Game Dice: Perfect as a digital substitute when dice are lost or when there's no space to roll physical dice.
- Fair Decision Making: Entrust small daily choices like choosing cleaning duties or dinner menus to "fate".
Implementation Details
Special efforts were made to balance digital convenience with an analog-like feel.
- Shake Animation: Added a shake effect to the numbers at the moment of rolling to create a sense of movement as if you're actually rolling them.
- History Management: List view of past rolls. Both the total value and the breakdown per die are saved, making it easy to review results.
- Process Completely Locally: Everything from random number generation to history saving is completed within the browser. Results appear instantly with no server lag.
Useful Facts
Introducing some interesting properties of dice probabilities.
- Law of Expected Values: For example, the expected value of a D6 is 3.5. When rolling multiple dice, the results tend to gather around multiples of this value, which helps with risk management.
- Approaching Normal Distribution: The more dice you roll (e.g., 3D6), the more the results tend to cluster around the median value (10-11). Understanding this helps in judging game balance.
- Precision of Digital Randomness: This tool uses standard JavaScript random numbers, which maintain more than enough fairness for everyday gaming use.
