The useful answer

Start official: opneon.com and the Steam page carry the news and support. Two community wikis — wiki.gg and Fandom — hold the card data, and two subreddits, r/TCGCardShopSim and r/TCGCardShopSimulator, hold the crowd knowledge. Always check a page's version date before trusting a number.

Official channels

OPNeon Games' site lists their projects, including TCG Card Shop Simulator and the standalone Tetramon Duel Master mobile game. The Steam page remains the practical hub: release announcements, patch notes, the discussions board and the link to the official Discord. When a claim matters — a release date, a feature, a fix — land here first.

Two wikis, both community-run

tcgcardshopsimulator.wiki.gg organizes card lists by rarity, expansions, the in-game phone apps and patch notes, and is open for anyone registered to edit. The Fandom wiki covers similar ground; its card pages catalogued the 1,452-card set at our check. Neither is official — both are volunteer work, and both contain pages written mid-Early-Access that no longer match 1.0. Cross-check any number against your own build before spending in-game money on it.

Two subreddits

The community splits across r/TCGCardShopSim and r/TCGCardShopSimulator — both active, both self-described as unofficial. They are at their best for exactly the things wikis handle worst: “is anyone else seeing this bug after the patch”, “which of these mods still work together”, and shop-showcase posts. The mod-troubleshooting crowd-diagnosis our post-update checklist draws on lives largely there.

Videos, with version notes

YouTube carries the walkthroughs, and our video desk curates the useful ones with an unusual discipline: every video is labelled with the version it was recorded on, because Early Access footage is a historical document, not a current guide. The same rule applies to everything on this page — the newer the patch, the more older answers drift.

How this site uses community information

Cardshop Fieldguide is itself an independent fan resource, and our rule is simple: official statements for facts, community sources for experiences, and every claim labelled with what it is and when it was checked. That policy — including what we refuse to publish — is on the about page. If you find a claim here that a current build contradicts, the underlying sources are linked on every guide.

Sources & scope

Official facts and editorial suggestions are identified in the text. No current-build gameplay benchmark was performed for this guide. Old video results are not treated as 1.0 measurements.
