Good news for Gundam Card Game fans — a brand-new Gundam Card Game Simulator is now live, and it looks and feels very similar to the popular One Piece Card Game Simulator (OPTCG Sim). Best of all, it’s free to play and web-based, meaning you don’t need to install anything.

How to Access the Gundam Card Game Simulator
Getting started is simple:
- Head over to ZumboSim.
- Log in using your Discord account (required).
- Import decks built with EXBurst, gundams.dev, or Egman’s deckbuilder.
- Start dueling against other players or invite a friend for a private match.
Key Features Players Will Love
The simulator was created with both casual and competitive players in mind, offering features that make matches smooth and fun:
- 🎥 Spectator Mode – Watch other games in real-time and learn new strategies.
- ⏪ Rewind Function – Fixes gameplay whenever lag causes issues.
- ⏩ Auto Pass Option – Skip phases where you don’t have skills or commands, keeping the game flowing.
- 💬 In-Game Chat – Say “GG” or “Good Game” at the end of your match.
- 🌍 Public & Private Hosting – Create open lobbies or invite only specific players and spectators.
Current Limitations
Like any new platform, ZumboSim has a few areas for improvement:
- ⚠️ Occasional Lag – While matches sometimes stutter, the rewind feature helps smooth things out.
- 🎴 No Alternate Art Recognition (Yet) – Currently, the system doesn’t recognize alternate art cards, but fans are hoping this will be added in future updates.
How It Compares to OPTCG Sim
Since ZumboSim is inspired by the One Piece Card Game Simulator (OPTCG Sim), many players will find the experience familiar. Both platforms share features such as:
- Web-based access (no downloads required).
- Deck importing from popular builders.
- Public and private lobbies for hosting games.
- Spectator and chat functions.
However, ZumboSim also brings its own twists:
- The rewind function is a lifesaver for fixing lag-related issues, something OPTCG Sim doesn’t emphasize as strongly.
- The platform is still in its early stages, meaning some features (like alternate art recognition) are missing, but updates are expected.
- Gundam-specific mechanics such as skill timing are supported with the auto pass feature, making games faster.
For players already used to OPTCG Sim, the learning curve is practically zero — you’ll feel right at home.
The Developer Behind the Project
This simulator was created by Dan Ugore, who deserves massive credit and, as fans say, a “3000x shout out” for bringing this dream project to life.
Why Fans Are Excited
With new sets of GD and ST coming soon, the community hopes ZumboSim will continue to receive updates to support the latest releases. If development keeps moving forward, this platform could become the go-to hub for online Gundam Card Game battles.
Whether you’re testing decks, playing with friends, or just spectating matches, ZumboSim is an exciting new tool for the Gundam community.
