About this app

**Know your odds before you roll — and invent dice nobody has rolled before.**
Dice Prophet computes the exact probability of any dice combination — no
simulations, no approximations — and shows it as a beautiful interactive
graph.

🎨 **Built for custom dice.** Define any die you can imagine by listing its
faces: 1,1,2,2,3,5 — duplicate faces, skipped numbers, even negative faces
(-1,0,1). Mix custom dice with standard d4–d100 in one pool and see exactly
how your invention behaves.

🧙 **Made for game designers and dungeon masters.** Balancing a homebrew
weapon? Designing a board game's combat dice? Testing whether your special
house-rule die breaks the game? Dice Prophet shows the true distribution of
any mechanic before your players ever roll it — compare designs side by side
and tune them with real numbers instead of gut feeling.

🎲 **Any rule you can think of:** exploding dice, rerolls, keep/drop the
highest or lowest, success counting for dice pools, target numbers,
cumulative "at least" odds.

🪜 **Chain steps without formulas:** roll a d6 and a d4, keep the highest,
add another d4 — build any multi-stage mechanic step by step, no math
notation needed.

⚔️ **Attack calculator:** d20 + bonus vs armor class with criticals — see
real damage-per-attack including misses.

📊 **Compare builds:** overlay distributions (d12 vs 2d6?), check your
chance to beat a target, see what you'll roll 90% of the time.
