4-Sided Dice Roller Calculator
Choose how many d4 dice to roll, view the individual outcomes, totals, and averages, and explore randomness for gaming or teaching.
Results: 4, 1, 3, 3, 3, 4, 3, 4
Total: 25
Average: 3.13
How to Use This Calculator
- Enter the number of d4 dice you want to roll.
- Click the roll button to generate random outcomes.
- Review individual results, totals, and averages.
- Repeat to sample different scenarios or to simulate tabletop game mechanics.
Formula
Each d4 outcome is uniform over {1, 2, 3, 4}
Expected value = (1 + 4) / 2 = 2.5
Variance = [(4² − 1) / 12] ≈ 1.25, standard deviation ≈ 1.118
Total expected value for n dice = 2.5 × n
Full Description
Four-sided dice (d4) appear frequently in tabletop RPGs and probability exercises. This virtual roller simulates fair outcomes and summarizes results to facilitate quick experimentation or demonstrations.
Frequently Asked Questions
Are the results independent?
Yes. Each die is rolled independently using uniform randomness.
Can I simulate exploding dice?
This specific tool doesn’t support exploding mechanics. Use it for basic d4 rolls.
What about cumulative history?
Only the most recent roll set is displayed. Copy results externally if you need long-term tracking.
Is the RNG deterministic?
No. Each click produces fresh random values provided by JavaScript’s pseudo-random generator.
