About the Game
Mystery Egg Shop Simulator is a simulation game where you manage every aspect of a shop that sells collectible mystery eggs.
Open Eggs, Find Figures
The core of your business offers a strategic choice:
Sell Sealed: Sell mystery eggs directly to customers for a consistent, reliable income.
Open for Profit: Open the eggs yourself. Inside are collectible action figures with different rarities (Common, Uncommon, Rare, Legendary). A rare figure is worth far more than the sealed egg.
Expand Customize Manage Your Shop
You are in full control. Start with an empty space and build it out.
Physical Stocking: Order inventory using your in-store computer and physically place the eggs on your shelves.
Price Control: Set the price for each type of egg and adjust based on supply and demand.
Checkout & Operations: Scan items, take cash and card payments, and keep your store clean to attract more customers.
Expansion: Use your profits to expand your store's physical space, buy more shelving, and upgrade your point-of-sale system.
Craft and Sell Dioramas
Don't just sell loose figures. Maximize their value with the crafting system.
Themed Sets: Collect figures that belong to the same theme, like "Space," "Fantasy," or "Dinosaurs."
Build Dioramas: Place a complete set of themed figures onto the corresponding diorama base.
Sell for High Value: A finished diorama is a premium product that sells for a significantly higher price than the sum of its parts. This is the key to making big money.
Grow Your Business in New Ways
Earn more than the usual market price by exploring several ways to buy, sell, and trade:
In-Store Auctions – Put valuable figures up for auction and let customers compete with higher bids.
Black Market Merchant – Meet a mysterious merchant offering a rotating selection of limited themed eggs and exclusive dioramas.
Online Orders – Fulfil simulated customer orders for specific items and earn premium payouts above their standard market value.
KEY FEATURES
First-Person Shop Management: Physically run your store, from stocking shelves to operating the cash register.
Inventory and Price Management: Order stock via a computer and set your own prices for all products.
Unbox and Collect: Open mystery eggs to find hundreds of different action figures across multiple themed sets.
Figure Rarity System: Figures range from common to Epic, directly impacting their value.
Diorama Crafting System: Combine figures of the same theme on a diorama base to create high-value collector's items.
Store Expansion and Upgrades: Grow your store's physical size, improve your equipment, and customize its appearance.
Online Marketplace: Real Player to Player online marketplace, where you can sell your rare findings to other players or buy the items you need to complete your collection
Online Order System: Besides in-store customers, you can receive in-game online orders, which you can fulfill for extra cash
Day/Night Cycle & Customer AI: Manage your shop during open hours and prepare for the next day after closing.

Version Information
Steam Patch Notes
Official update history
- We’ve fixed an issue that could prevent some players’ saves from appearing after the Steam Cloud update and block them from starting a new game.
- Older save entries with missing files will no longer block the import of other saves. Those entries will remain unavailable, while their existing save information is preserved.
Your shop can now travel with you! Autosaves and manual save slots sync through Steam Cloud, so you can pick up where you left off on another computer using the same Steam account.
Your existing saves are preserved. Let Steam finish syncing after you close the game before switching devices.
Happy shopkeeping!
Improved customer shopping behavior!
- Customers now find and select stocked products more reliably.
- Customers can choose an alternative product when their original choice is unavailable.
- Customers briefly wait for busy shelves.
- Fixed misleading “product not found” complaints when stock is still available.
Delivery Pickup Fix
- Fixed an issue where a delivery box could become stuck on the truck after loading a save, preventing both players and sorter staff from picking it up.
- Stocker Improvements
- Fixed an issue where stockers returned mostly full boxes to storage after placing only a few eggs. Stockers can now continue restocking while customers shop, reducing repeated trips between shelves and the warehouse.
Other Fixes
- The game now keeps running in the background when you Alt+Tab, so your shop can continue operating while you switch to another window.
- Fixed an issue where UI animations could continue running after switching scenes, causing errors when loading a game.
Stock App Fix
- Fixed an issue where products delivered through online orders weren’t deducted from the stock tracker. Stock counts now update correctly when an order is successfully delivered.
Staff Storage & Diorama Fixes
- Stockers now return boxes with leftover products to storage racks.
- Sorters now collect loose boxes from warehouse floors.
- Improved staff recovery when racks are full or unreachable. Staff try another rack, then use the delivery area if needed.
UI Fixes
- Fixed errors when diorama filters have no matching results.
- Fixed diorama inventory controls after changing filters or closing the viewer.
- Fixed an issue where eggs returned from a shelf to a box could prevent a stocked storage rack from being placed after moving it.
- Fixed an issue where taking a box while moving a storage rack could leave the rack stuck in moving mode. Box pickup is now disabled during furniture movement.
- Fixed an issue where the “Add to Inventory” prompt could disappear after opening an egg while staff restocked dioramas or customers returned unpaid items to shelves, leaving players unable to collect their figure.
- Fixed an issue where loading a save made at the end of the day could charge daily expenses again.The fix also applies to existing saves, preventing further duplicate charges.
- Fixed an issue where the Re-Box (Q) action stayed active after taking a box from a storage rack, allowing an empty rack to be reboxed while facing away or out of range.
Bank App
Reward for loan repayment on time and loanable amounts for lower tiers increased
Sorter Staff Improvement
Sorters now unload product and furniture boxes directly from delivery trucks and carry them to available storage racks. When racks are full, they leave boxes at the delivery point for storage later.
Stockers now automatically fill compatible empty shelves using products from storage racks.
After topping up a shelf, they carry remaining products to other available shelves instead of dropping the box.
Stockers prioritize restocking existing products before filling unassigned empty shelves.
Open Products Directly from Boxes
You can now take mystery eggs and boxed dioramas directly from an open box on the ground—no shelf needed! Look at the box and right-click to take a product into your hands, then open it as usual. Controller players can use X / Square.
- Added Quick Open for Mystery Eggs, allowing players to skip the egg-opening animation.
- Standard opening remains available
- Fixed an issue where placing a figure on a Rare or Epic Kitty-Kitty diorama triggered an exception.

- Decreased the poster prices
- Adjusted drop rates for figures in later themes to ensure a more balanced distribution.
Staff Storage Improvements

- Both employees can now be hired before the warehouse is unlocked.
- Storage racks placed in the warehouse continue to work as before.
- Staff hire requirement levels are decreased
- Fixed an occasional error when loading a save and opening the shop.
- Fixed an error that could occur when returning to the main menu or closing the game.
- Improved general stability during scene transitions.
- Fixed an issue that could show a nonexistent save named “Emporium” in the save menu.

- Fixed an issue where the online marketplace backend capped the viewable listing count to 100. This allows the marketplace to display a much larger selection of active listings when browsing.

- Game progress and save-slot information are now saved together to prevent mismatched or inaccessible saves.
- Improved backup recovery and corruption handling.

Customer Shopping Improvements
- Customers now have budgets that better match the products they intend to buy, which will present a better price tolerance. Also price analysis UI is adjusted better reflect the customer price tolerance.
Fixed an issue where newly completed dioramas would not appear in the Marketplace listing picker until the next in-game day. They can now be listed immediately after completion.
Fixed an issue where empty dioramas could become stuck on product shelves and could not be picked up. Dioramas already affected should work correctly after reloading your save.
Fixed an exploit that allowed players to repeatedly increase their credit score by taking and immediately repaying a $0 loan.
Added safeguards to ensure only valid loans can improve credit score and loan-related achievement progress.
Fixed an issue where customers could stop recognizing stocked dioramas and other products. This could prevent customers from entering the shop or purchasing certain items until the game was reloaded.
Fixed an issue that could let empty or incomplete dioramas be placed on shelves after switching dioramas in the inventory. Dioramas must now be complete before they can be displayed.
Save Recovery Improvements
Improved save protection to reduce the risk of progress loss during interrupted saves.
The game can now automatically recover from a valid backup when the primary save is damaged.
Corrupted save slots no longer prevent other healthy slots from loading.
Damaged files are preserved for possible support or manual recovery.
Added clearer messages when a save is recovered or cannot be loaded safely.
Fixed backup detection and cleanup issues.
These improvements cannot restore saves that were already completely corrupted, but they should make future save failures safer and more recoverable.

Figures to become unavailable or behave incorrectly in the inventory.
Fixed an issue where the Money, Tasks, Day, and Time displays could disappear after opening the first diorama and remain hidden until the game was reloaded.
