About FeeBay Simulator
FeeBay Simulator drops you into a parody online marketplace where you start with $500, a folding table, and a lot of confidence. The core loop is buying low‑priced cards, selling them at higher prices, and gradually expanding your reselling empire while navigating quirky listings and market trends.
The game features a living marketplace feed, seven unlockable markets, three grading houses, and a custom 1339‑card TCG collection. You can run your own storefront, open mystery lots, and use upgrades, achievements, and automation to streamline the grind, all while enjoying light and dark UI modes.
01 / THE GUIDE
Living Marketplace Feed
The main screen scrolls a feed of parody listings where sellers may misprice cards, claim false authenticity, or hype common items. Each entry includes details like centering, condition, and price, letting you read between the lines to spot hidden value.
Market dynamics shift over time: trend events can boost prices, conventions can cause spikes, and reprints can crash values. Observing these fluctuations helps you decide when to buy, hold, or sell for profit.
- Compare listed prices with known card values before purchasing.
- Watch for trend events that temporarily inflate specific sets.
02 / THE GUIDE
Three Grading Companies
Cards you think might be gems can be shipped to one of three grading houses: speedy ZAG, prestigious PZA, or unpredictable Bucket Grading. Each imposes its own fees, turnaround times, and randomness in final grades.
After grading, you receive a slab that may reach Gem Mint 10, especially with Bucket’s occasional special grades. The grading outcome directly influences resale value, making the choice of house a strategic consideration.
- Use ZAG for faster turnaround when you need cash quickly.
- Consider Bucket for a chance at a special grade despite higher risk.

Running Your Own Storefront
You can list cards at prices you set, watching buyers either purchase instantly, wait, or bail. Funds accumulate in a storefront wallet and are subject to a 14% FeeBay cut before withdrawal.
Upgrades exist to streamline this workflow, though specifics are not detailed. Managing listings efficiently can improve cash flow and reduce idle inventory.
- Set competitive prices to attract instant buyers.
- Monitor the 14% cut to price items profitably.

Steam Workshop Modding
FeeBay includes a full suite for the modding community, accessible via Steam Workshop. Mods can add new cards, alter grading company names, adjust balance, or introduce meme content. Community‑created mods carry their own responsibilities.
While the base game’s art is by AaronSprites, mods may contain AI‑generated images, which are not reflective of the official game. This openness encourages continual content expansion.
- Check mod descriptions for any AI‑generated assets if you prefer hand‑drawn art.
- Back up your collection before installing large content mods.

Business Levels, Upgrades, and Automation
The game features business levels, upgrades, achievements, automation, and employees. These tools help streamline buying, grading, and selling processes, reducing manual micromanagement.
Automation can handle repetitive tasks, and the goblin‑run auction house offers bidding with auto‑snipe, allowing you to focus on strategic market decisions.
- Prioritize upgrades that reduce manual listing time.
- Use automation to stay competitive in fast‑moving auctions.
