TCG Card Shop Simulator — tools & guides Community-sourced

You run a trading-card shop: buy stock, set prices, serve customers, hire staff and grow the store. This section gives you the numbers side of that job — an unofficial player-made resource for OPNeon Games' sim on Steam.

Section status: every guide below carries sourced content — each number links its source, and pages say plainly where public data doesn't exist (exact refusal thresholds, pack odds). Built against game version 1.0 (2026-09-15); see the changelog for version coverage and every correction.

What this section is not

It's not a wiki, not a news feed, and not affiliated with OPNeon Games. It covers the questions players actually ask — starting with pricing — and labels everything we haven't verified ourselves. If something here is wrong or outdated, please tell us.
