CHOOMDECK is a free, browser-based Cyberpunk 2077 TCG simulator for the official Cyberpunk Trading Card Game — the tabletop TCG set in the world of Cyberpunk 2077. Play full rules-enforced matches against real opponents or the AI, build decks from every card in the Welcome to Night City set, and test them before the retail launch on November 6, 2026. No download, no install — it runs on a phone.
Quick-match into a public room, open a private table with a room code, or hand the phone across the table for hot-seat. The engine automates the whole game — Gigs, Legends, Eddies, combat, steals, and every card's printed effect — and online matches run both clients in lockstep, so the two boards can never disagree. NETWATCH mode plays you against an AI that genuinely tries to win; BRAINDANCE coaches your first matches with advice read from your own cards.
Build from all 150 cards — 26 Legends, 73 Units, 34 Programs and 17 Gear across Red, Yellow, Blue and Green. The builder enforces the real deckbuilding rules as you click: 40–50 main-deck cards, exactly three unique Legends, copy limits, and each color's RAM ceiling from your Legends, with an AVAILABLE RAM readout and a fits-my-Legends filter. The analyzer reads your curve, RAM budget and true draw odds; saved replays let you scrub back through any match.
FIRST GIG is a guided first match that teaches the turn structure hands-on. The in-app rules glossary covers every keyword — {Blocker}, {Go Solo}, {Adrenaline}, {Quick}, {Call} — with the official wording. Card data and market prices come from CHOOMDEX, the Cyberpunk TCG card database and collectibles price guide.
