What This Dice Roller Does Better
Fast single-click rolling
Quick enough for casual use, clean enough for repeat use, and smart enough to stay out of your way.
Advanced dice language
Exploding dice, rerolls, keep/drop logic, Success Mode, and d20 advantage handling without the usual headache.
Real session utility
D&D helpers, MTG Commander tracking, history, sharing, and presets make it feel like an actual tool, not just a novelty button.
Roll Anything
Tip: We’ll sort from highest to lowest and show ability modifiers automatically.
We follow the 5e formula: 8 + proficiency + ability modifier + misc.
A natural 20 = regain 1 HP. A natural 1 = 2 failures.
Use Shuffle Order after adding players to randomize seating.
London Mulligan Helper
London Mulligan: draw your full hand size, then put one card per mulligan on the bottom of your library.
Advanced options
Advantage/Disadvantage only affects a single d20 term (auto-expands to 2d20 keep highest/lowest).

Frequently Asked Questions
How do I roll dice or build a custom expression?
Tap any die to roll instantly. Type a recipe like 2d6+3 or 4d6kh3 + 1d8 in the box and press Roll or Enter. Shift+Click a die to append it to the box without rolling.
What dice syntax is supported?
NdM (e.g., 3d8), arithmetic (+ -), explode !, reroll rN (reroll ≤ N), keep/drop (khX, klX, dhX, dlX), and success mode (counts dice ≥ target). Example: 8d6!r1kh6 + 2.
How do Advantage and Disadvantage work?
Toggle Advantage or Disadvantage above the box. The first d20 in your expression is expanded to 2d20kh1 or 2d20kl1. Other dice are unchanged unless you write them explicitly.
What does explode ! do?
When a die rolls its maximum value it “explodes”—roll it again and add. Explosions can chain if you hit the max again. Good for swingy effects like 1d6! or 8d6!.
How do rerolls work (rN)?
r1 rerolls any result ≤ 1; r2 rerolls 1s and 2s, and so on. The die is rolled again until it beats the threshold, with a sensible safety cap to avoid infinite loops.
What is Success mode?
Enable Success mode in Advanced options, set a target, then roll. The total becomes “number of dice ≥ target”. Example: 10d10 with target 8 counts how many are 8, 9, or 10.
Can I share or repeat a roll?
Yes. Click Share to copy a link that auto-loads your expression (and can auto-roll). The History list lets you repeat past rolls with one click.
Is the randomness fair?
The roller uses your browser’s RNG (Math.random()). It’s suitable for tabletop play but not for cryptographic/security use. Results aren’t biased by the app.
Does this work offline?
Yes. Once the page is loaded, all rolling happens in your browser.
What browsers and devices are supported?
Modern Chromium, Firefox, and Safari on desktop and mobile. If something looks off, update your browser and disable aggressive content blockers for the page.
How do I turn on sound or fix audio?
Use the Sound toggle under History. If you don’t hear anything, click once on the page to grant audio, then roll. Some browsers block autoplay until a user gesture.
Is any personal data stored?
No account is required. Rolls happen in your browser. If you click Share you copy a URL containing your expression; no server-side history is stored by this tool.
D&D Tools
How do I generate ability scores?
Open the D&D tab → Ability Scores. Choose a method (4d6kh3, 3d6, 5d4kh3), optionally enable Reroll 1s, then Roll ×6. We sort high→low and show mods automatically.
How do I calculate Spell Save DC?
Go to D&D → Save DC. Pick your Proficiency, enter your casting Ability Mod and any Misc bonus. We display 8 + prof + mod + misc and the current result.
How do Death Saves work in the app?
In D&D → Death Saves, use the + pills to mark successes/failures or click Roll Death Save. A nat 20 stabilizes at 1 HP; a nat 1 is two failures. Use Stabilize/Reset as needed.
MTG Tools
How do I add players and set starting life?
Open the MTG tab → Life & Counters. Select 20/30/40, then Add Player as needed. Life buttons are color-coded (−5/−1 red, +1/+5 white).
Can I track Poison, Energy, and Experience?
Yes. Each player card has ± controls for Poison, Energy, and Experience. Values are shown per player.
What are Monarch and Initiative toggles?
They’re per-player flags you can switch on/off to track those game states in Commander and related formats.
How does the Turn Tracker work?
In MTG → Turn Tracker, click Shuffle Order to randomize seating after you’ve added players, Pick First Player to start, then use Prev/Next. The banner shows Turn # and Active player.
What does the London Mulligan helper do?
In MTG → Randomizers, set Hand Size and Mulligans Taken. We show “Draw N, then put M on bottom” according to the London Mulligan rules.
WordPress & Customization
How do I embed the roller on a page?
Add the shortcode [ssa_dice_roller] to any post/page. Optional attributes: title, examples, sound (mp3 URL), and presets (CSV of labels/expressions).
Can I customize the preset chips?
Yes. Example: [ssa_dice_roller presets="Attack:1d20+5, Fireball:8d6, Stats:4d6kh3"]. Unlabeled items use their expression as the label.
Can I hide tabs I don’t need?
Use CSS to hide .ssa-mode [data-mode="dd"] or [data-mode="mtg"]. (A shortcode flag isn’t exposed yet.)
Can I export my roll history?
Not yet. For now, use Share links for specific expressions or copy the breakdown text.
Why is some text hard to read with my theme?
The plugin ships with defensive CSS to keep text legible on dark backgrounds. If your theme still overrides it, enqueue the plugin last or add a tiny CSS rule with higher specificity to force the desired colors.
