Expert Tips

D20 Dominates D&D: Most D&D rolls use d20 (attacks, skill checks, saves). Critical hit on 20, critical fail on 1. Probabilities matter—20-sided die gives 5% chance per number.
Dice Notation Standard: 2d6 means "roll two 6-sided dice and add them." 3d8+5 means "roll three 8-sided dice, sum them, add 5." Universal across all tabletop RPGs.
Probability Curves: Single die = flat distribution (each number equally likely). Multiple dice = bell curve (middle numbers more common). 2d6: 7 appears 17% of time, 2 or 12 only 3%.
Physical Dice Still Matter: Digital convenience vs tactile satisfaction. Serious players use physical dice for important rolls, digital for quick NPC rolls or large quantities.

Essential Fundamentals — Dice basics

Dice Types & Notation

Standard Polyhedral Set: D4, D6, D8, D10, D12, D20 form standard RPG dice set. D10 pairs (00-90 and 0-9) create D100 for percentile rolls.
Dice Notation: 2d6 means roll two 6-sided dice and add them. 3d8+5 means roll three 8-sided dice, sum them, then add 5. Standard across all tabletop RPGs.

Probability Basics

Single Die Distribution: Each face on fair die has equal probability. D6 has 16.7% chance per number. D20 has 5% chance per number.
Multiple Dice Curves: Rolling multiple dice creates bell curve—middle results more common. 2d6: rolling 7 appears 17% of time vs 2 or 12 only 3%.

Advanced Strategies — RPG applications

Gaming Mechanics

Critical Hits: Rolling maximum number (20 on D20) often means automatic success or double damage in game systems.
Advantage/Disadvantage: Roll two D20s, take higher (advantage) or lower (disadvantage) result. Changes probability significantly—17% vs 10% for rolling 15+ with advantage.
