Empowering Tabletop Gaming at the Speed of Thought

The Heritage of Pen, Paper & Pixel (2004–2026)

More than two decades ago, in the golden era of the D&D 3.5 edition and the rise of the Open Gaming License (OGL), game designer Jans Carton registered PenPaperPixel.org. His mission was revolutionary: to prove that computers and digital software should not replace the magic of sitting around a physical table with friends, but rather augment and accelerate it.

His original tools—the Java-based d20 Dice Bag, the pioneering d20 Encounter Calculator, and the widely cited Tabletop Projection Tutorial—earned prestigious recognition across the tabletop community, including an **ENnie Award** and permanent citations in academic works and the English Wikipedia’s foundational article on Computer-Assisted Gaming.

Today, Pen, Paper & Pixel continues that proud tradition. We have modernized every tool for modern web standards—rebuilt from scratch in 100% client-side HTML5, CSS Grid, and the Web Audio API. There are no tracking scripts, no paywalls, no mandatory account signups, and zero server lag.

Why 100% Client-Side Architecture Matters for Tabletop Gaming

When you are running a four-hour tabletop session in a basement, a local hobby shop, or a convention hall, internet connectivity is notoriously unreliable. Heavy commercial web apps like D&D Beyond or Roll20 require megabytes of JavaScript frameworks, constant server handshakes, and frequent authentication checks.

Pen, Paper & Pixel is architected with a different philosophy:

• Instant Execution: All calculations, dice physics, and spell searches happen locally inside your browser's V8 or WebKit JavaScript engine in under 5 milliseconds.
• Zero Data Tracking: Your character stats, party compositions, and roll histories are stored in your device's private localStorage. Nothing is sent to an external server.
• Edge-Cached Worldwide: Hosted across Cloudflare Pages' global edge network in 300+ cities, pages load in under 200 milliseconds globally.

Quick Combat Action Economy Cheat Sheet for 5e

To help Dungeon Masters and players maintain high-tempo combat rounds alongside our digital calculators, keep these core 5e action economy definitions at hand during your session:

• Action: Your main physical or magical effort on your turn. Standard actions include Attack, Cast a Spell (1 action casting time), Dash (double your movement speed for the turn), Disengage (your movement doesn't provoke opportunity attacks), Dodge (attacks against you have disadvantage, your Dexterity saves have advantage), Help (give an ally advantage on an attack or check), Hide (make a Dexterity Stealth check to become unseen), and Ready an Action (prepare a reaction trigger).
• Bonus Action: A swift, supplementary action granted by specific class abilities, spells, or feats. Examples include Rogues' Cunning Action (Dash, Disengage, or Hide as a bonus action), Barbarians' Rage, and quick spells such as Misty Step and Healing Word. You only have one bonus action per turn, regardless of how many abilities qualify.
• Reaction: An instant response to a trigger of another creature's turn or your own. Common reactions include Opportunity Attacks (triggered when an enemy moves out of your melee reach without disengaging), the Shield spell (triggered when you are hit by an attack), and Counterspell (triggered when you see a creature casting a spell within 60 feet). You only get one reaction per round, refreshing at the start of your turn.
• Free Object Interaction: You can interact with one object or feature of the environment for free during either your move or your action (such as drawing a sword, opening an unlocked door, or pulling a lever). Interacting with a second object on the same turn requires spending your Action.

Resting & Resource Recovery Guidelines

Balancing daily encounters requires pacing player resource expenditure between rests:

• Short Rest (At Least 1 Hour): Characters can spend one or more of their Hit Dice to regain lost hit points (rolling the die and adding their Constitution modifier). Warlocks regain all their Pact Magic spell slots, Fighters regain Action Surge and Second Wind, Monks regain Ki points, and Druids regain Wild Shape uses.
• Long Rest (At Least 8 Hours): Characters regain all lost hit points and up to half of their total maximum Hit Dice. Spellcasters regain all expended spell slots. A character can only benefit from one Long Rest in a 24-hour period, and must have at least 1 hit point at the start of the rest to gain its benefits.
