Prismwar — Six-Color Card Battler

Prismwar is an offline six-colour card game you play against a computer rival — no account, no sign-in, and no network connection of any kind. HOW IT WORKS Pick one of eight ready-built starter decks and play a guided first match. Winning matches, finishing daily and weekly quests and hitting achievements earn packs; packs add cards to a 250-card set called Refraction. Once you own cards you can build your own 40-card decks, either by hand or by pressing Quick build and letting the game assemble a legal deck from what you actually own. Duplicates past the third copy turn into shards automatically, and shards craft any card you are still missing. Every match is deterministic from its seed, so a finished game can be saved as a short replay code and stepped through turn by turn. WHAT IS IN IT • Play a full match against a rival with three difficulty settings and eight rival decks. • Collect 240 cards across six colours — Order, Current, Ledger, Spark, Root and the Undertow — plus ten Ascendants that only a signed code unlocks. • Build decks with a live mana curve, a legality check and suggestions that catch a deck whose colour pips no Wellspring can pay. • Earn packs from six daily quests, three weekly quests, achievements and your first win each day. • Draft and seal from generated packs, or run a gauntlet against three rivals on one deck. • Send a challenge code to a friend: they play the same seed with the same decks and compare results. • Watch a replay of any of your last ten matches, or post a ledger card of your collection. • Read every card in a full-set browser with keyboard navigation, screen-reader labels and a reduce-motion setting. PRIVACY Prismwar makes no network requests. There is no analytics, no telemetry, no account and no remote code. Your profile — cards, decks, quests and replays — is stored only in this browser's extension storage, and nothing is synced anywhere. You can export it to a JSON file and import it back at any time, and that file never leaves your machine unless you move it yourself. PERMISSIONS • Storage — keeps your collection, decks, quest progress and settings on this device. It is the only permission the extension asks for, and without it nothing you do is saved. SUPPORT AND CHANGELOG Problems, ideas and bug reports: dhseadev.online/projects/prismwar/ New in 0.6.0: a colour letter and coloured edge on every card so colour is never the only cue; a First Steps guide after the tutorial; Quick build for one-click legal decks with plain-language deck suggestions; an explanation of why a duplicate pack card becomes shards; a "coming from another card game" section in the rules; the Rival's key moments in the match summary; and a visible mark when a save has been edited outside the game.
