RollSpawn turns character creation into a game. Roll real 3D physics dice to randomly generate complete, rules-legal fifth edition characters - from species and class to ability scores and spells. ROLL YOUR DESTINY Swipe to throw beautifully rendered 3D dice powered by real physics simulation. Each roll determines a different part of your character: species, class, subclass, background, ability scores, and more. Watch your hero take shape one throw at a time. Every character is a surprise. That's the point. HOW IT WORKS - Roll a d10 for species (9 options from the 2024 Systems Reference Document) - Roll a d12 for class (all 12 core classes) - Roll for subclass, background, and alignment - Roll 4d6 drop lowest for each ability score - six satisfying throws - Pick spells your way: random, strategic presets, or manual selection PLAY YOUR WAY Lock any choice before rolling if you already know what you want. Reroll any step once for free. The randomness inspires - it never traps you. THREE WAYS TO PICK SPELLS - Random: Let fate decide. Spells flip over one by one. - Strategic: Choose a preset (Powerful, Creative, Survivor, Balanced, Unique) and let the app optimize your loadout. - Manual: Browse every available spell with plain-English descriptions, category filters, and new-player recommendations. BUILT FOR EVERYONE Whether you're a veteran player looking for creative constraints, a new player overwhelmed by choices, or a game master who needs a quick NPC, RollSpawn delivers a complete character sheet in under two minutes. YOUR CHARACTER VAULT Save characters to your local vault. Review full character sheets with ability scores, modifiers, proficiencies, spells, and equipment. Export as text or JSON to share with your group. PREMIUM UPGRADE ($4.99, one-time) - Unlimited saved characters (free tier: 5) - PDF character sheet export - Support independent development NO ADS.

It all starts with a message. Behind it: a 1954 nuclear test, a frequency we're all hearing without knowing it, and a silent colonization that has been advancing for decades with no one to stop it. A CONSPIRACY THRILLER IN YOUR MESSENGER Castle Bravo is an interactive story where characters text you, send you voice messages, photos, and files. The story combines declassified nuclear test records with interactive fiction. YOU WRITE IN YOUR OWN WORDS You write freely to the characters instead of choosing preset responses. They react to what you say, and each conversation builds a different relationship: who you trust, what you share, how far you go. An authentic, immersive experience where the way you talk is part of the game. FEATURES - Mystery and conspiracy game told through messages - Open-ended responses: real conversations with the characters - Voice messages, photos, files, and documents sent straight to your phone - Based on real events
