Type 2d6+1d8+3 adv and watch every die break out on its own — crits flagged, modifier added once. Presets and roll stats keep your whole session at hand.
PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase.
Roll every polyhedral die your table needs — d4, d6, d8, d10, d12, d20 and d100 — with advantage, modifiers and full dice notation. Built for D&D, Pathfinder and any tabletop RPG session where the dice bag stayed at home.
Most dice apps stop at a random number. RPG Dice Roller understands how tabletop rolls actually work: type 2d6+1d8+3 adv into the formula bar and it parses the whole thing, rolls each group, keeps the higher of two dice, adds the modifier exactly once, and flags a natural 20 the instant it lands.
WHAT YOU GET
• A d20 with advantage in two taps — roll twice, keep the higher, with a haptic celebration the moment a crit hits
• Full dice notation: type 2d6+1d8+3 or 4d6 dis and get every die broken out per group, not just a total
• Up to 50 dice in one throw with a live per-die breakdown — an 8d6 Fireball shows all eight dice, then the sum
• Saved presets like "Longsword d20+5" that reorder by how often you use them, so your main attack is always the first chip
• A statistics dashboard that answers "are my dice cursed?" — face-by-face distribution, crit and fumble counters, average per die
• A complete roll history with timestamps, modifiers and advantage tags, so "you never rolled that" arguments end with receipts
PERFECT FOR
• D&D and Pathfinder players who left the dice bag at home
• Dungeon masters resolving NPC attacks fast behind the screen
• Board game nights where the dice keep rolling off the table
• New players learning the rules — the built-in dice guide explains ranges, averages and how advantage changes the odds
WHY NOT JUST USE PHYSICAL DICE?
Real dice can't tell you your average d20 across the whole campaign, re-roll an 8d6 in one tap, or prove the natural 20 happened at 9:42 pm. This keeps the ritual — one big tap, a tumble, a result — and adds the memory.
PRIVATE BY DEFAULT
Every roll stays on your device. No account, no ads, no tracking, no internet required.
PREMIUM (PURCHASE REQUIRED)
Pro unlocks unlimited saved presets, your complete roll history beyond the latest 100 rolls, and a shareable session log export. Choose a weekly plan, a yearly plan, or a one-time lifetime purchase.
Download RPG Dice Roller and have the d20 ready before the dice bag is even open.
