What you can do here
Create a private table, invite friends with a room code, or add computer opponents to practise. The website also publishes rules explanations, worked strategy examples, and instructions for using its browser interface. Reading guides does not require an account. Playing uses a browser-held seat credential rather than an email login.
Classic, Duel, and the other editions have different rules. Each edition page explains its own player count and actions. Our guides distinguish physical-game rules from conveniences of this implementation, such as the host controls and browser-based room recovery.
Who operates the website
The operator is Leo Hunter. For support, privacy requests, corrections, or rights-related questions, use the email address below or the Contact page. Gem Merchant is the website name; it is not a claim to be an incorporated company, a publisher, or an official representative of a game brand.
Independent status and third-party rights
Gem Merchant is an unofficial fan project. It is not affiliated with or endorsed by Space Cowboys, Asmodee, Marvel, The Pokémon Company, or the other owners of referenced game and character brands. Names identify the games being discussed; they do not imply a partnership.
The interface, explanations, and individual assets have different sources. We do not claim that all underlying game designs, names, character images, or music are original to Gem Merchant. Attribution is not permission. A rights holder can contact the operator with the specific page or asset and supporting details so the use can be reviewed.
How we write and correct guides
Rules articles link to publisher references where relevant. Strategy articles are our own explanations of decisions, with stated assumptions and worked examples. A hypothetical position is labelled as an example; it is not presented as a recorded match or evidence of a win rate. Calculated card statistics describe the card data shipped by this implementation, not an independent audit of every physical printing.
Computer opponents use programmed heuristics. Results against them are useful for learning the interface but do not establish tournament-level strategy. If you find an error, send the article URL, the relevant paragraph, and the rule or reproducible example that contradicts it. We can then investigate and update the explanation.
Cost and advertising
The website is free to use and uses Adsterra advertising on content pages and game pages. Trust pages such as About, Contact, Privacy, and Terms are not ad-monetized. There are no paid stakes or cash prizes. Website analytics and advertising providers are described in the Privacy Policy.
