DiceCalc is a TTRPG dice managmeent system for players and GMs. Here's what it does: Roll all of a character's dice simultaneously — see every attack, save, skill, and modifier roll all at once via the Roll All mode with character tabs. Still reroll per macro — long-press any single roll to edit or reroll just that macro without rerolling the rest, even in Roll All mode. In-depth macro inspection — Roll Macro mode focuses on macro options, allowing players to inspect rolls, rename, edit, and sort the macro list. Sort order here is also preserved in Roll All mode. Cryptographically secure random number generation — higher unpredictability, more randomer. Sortable character tabs with up to 100 macros each — whether you're running or playing a campaign, organize by character, encounter, monster, game system, or any other way you like. Every major TTRPG dice mechanic in one app — keep high/low, target numbers (successes), botches, exploding dice, crit detection, multi-roll comma separation for staged (verification) rolls, and yes... push dice! Constraint validation with red-highlighted error feedback — pathological expressions are caught before they run, no infinite loops or broken math. Persistent 300-roll history with timestamps — every roll logged with full roll breakdown and no truncation. Tap-and-hold context menus throughout — edit, duplicate, delete, rename, reroll wherever it makes sense. Localized in 7 languages — English, Spanish, Portuguese, German, French, Italian, Polish, with complete in-app manuals for each. 14-page in-app user manual — every feature documented with examples, no need to leave the app. Supports Android 8.0 and above — runs on devices going back a decade. Custom QWERTY keyboard for macro names — with locale-specific diacritics via long-press. Independent horizontal scroll per output row — nerd out inspecting long expressions, results, and roll details without truncation. Also... I'm giving it away for free till 09/31/2026 11:59:59 (JST).

Old Gold is a tabletop roleplaying game of daring exploration, creative problem-solving, and fast-paced tactical combat, in which you play as adventurers brave (or foolish) enough to delve into ruins and monster-haunted wilds for the old gold that awaits there. I hope you'll find as much joy with it as I have. Description Tabletop roleplaying games, such as Old Gold, follow a simple game loop: the Referee (or yourself, if playing solo) sets a scene, players say or do what their characters would, and the dice settle whatever is uncertain. Being a good Referee. You are a neutral arbiter. When a situation isn't covered by the rules, you make common-sense rulings. You let the story emerge from what the players do, and let the dice fall where they may. You are the eyes, ears, and nose of the players. You telegraph danger, and you reward clever thinking. Being a good Player. You ask lots of questions, take notes, draw maps. You ask what you would do, not only what your character would. You plan and work with your party. You play to win, but you're ready to lose.

Basic Roleplaying is the venerable "D100" engine that has powered Chaosium’s greatest hits for over four decades. Originally appearing as a slim booklet in 1980, it was most recently revitalized as the Basic Roleplaying: Universal Game Engine in 2023. In 2026, it stands as one of the industry's most important open-source platforms, released under the ORC License, allowing independent creators to build and sell their own games using its legendary, time-tested mechanics. Description BRP is a "genre-neutral" toolkit that discards character levels and rigid classes in favor of a pure skill-based system. Whether you are playing a Bronze Age warrior, a 1920s detective, or a futuristic mech pilot, the core experience remains the same: your character is defined by what they can do. Because it uses percentages (e.g., "I have a 65% chance to climb this wall"), it is widely considered the most intuitive and "transparent" RPG system for new players to understand at a glance. System Overview & Key Features The Universal D100 Engine Every action is resolved by rolling two ten-sided (d10) dice to get a result from 1 to 100. If you roll is equal to or under your skill rating, the action is deemed a success. This approach simplifies the mechanical process of the game, as there are no complex tables to keep track of and compare to decypher whether it is a success or failure. Organic Character Growth There is no "Experience Points" system in the traditional sense. Instead, when you succeed in using a skill, you mark a "Skill Check" on your character sheet. At certain stops in the game/story, the player rolls to see if the character improves in those skills, meaning your character evolves based specifically on the actions they performed (and succeeded at) during the game. Modular Rule Design The Universal Game Engine is designed with variations and systems to choose from. GMs can choose whether they prefer to just use "Hit Points" or add a more detailed wound system with "Hit Locations" for more realistic tactical consequences. Systems for Magic, Sorcery, Mutations, or Superpowers (depending on the setting) can be added, instead of being baked in the core mechanics, ensuring the mechanics always fit the theme of the game. Deadly and Tactical Combat BRP combat is grounded and dangerous. Unlike high-fantasy games where adventurers have a vast health pool, a single strike of a sword or bullet in BRP can be fatal. This encourages players to think creatively and use mechanics and terrain to their advantage. Talking their way out of situations is often seen as more reasonable (and survivable), than just treating every conflict as a forced combat situation. The ORC License Revolution By introducing to the Open RPG Creative (ORC) license, BRP started a wave of third-party "Powered by BRP". This has expanded the system into new genres like Cyberpunk, Wuxia, and Cozy Fantasy, all supported by a single, unified ruleset and system, compatible with most themes. Compatibility with "The Big Three" Because the core mechanics have remained the same since the beginning, a monster or spell from a 1980s supplement is almost always compatible with the modern 2026 engine. This gives GMs access to one of the largest libraries of pre-written adventures in tabletop gaming, spanning Call of Cthulhu, RuneQuest, and Pendragon.
