Open packs, collect absurd Grombos, and build your own card shop. Hunt rare and shiny cards, complete your collection, and decide which treasures to keep or sell. Decorate your store, deal with peculiar customers, and hire staff to keep business running.
Turn a little card shop into your own collector's paradise. Open packs of hand-drawn creatures, hunt for the card your collection is missing, and decide which prized pulls to keep or put up for sale.
Your next sale could pay for your next box. Unless you open all the stock yourself first.

A Grombodex to complete
Some packs will make you rich. Others will contain yet another copy of the Grombo you already own seventeen times.
Start with a cramped little store and work your way towards larger locations with more room, more customers, and considerably more things to worry about.
Buy furniture and place it wherever you want. Arrange shelves, showcases, tables, decorations, and products to create a shop that feels like yours.
There is no single perfect layout. Build an efficient card-selling machine, a cosy collector's paradise, or a complete retail disaster.
Running a card shop involves more than opening everything yourself.
Order packs, boxes, and accessories
Restock shelves before customers complain
Set prices for the cards in your showcases
Sell unwanted cards in bulk
Balance your profits with your own collection
Complete requests and deal with themed days
The cards you desperately want to keep are usually the ones worth the most money. Funny how that works.
Customers visit your store to browse, buy products, open packs, and spend time in the shop.
Their experiences can become reviews on Grooble Maps. Stock, prices, and the state of your business all influence what people think of the store.
Try to earn glowing reviews. Or proudly become the worst-rated card shop in the neighbourhood.
Invest your profits in the upgrade tree and automate part of the work to keep expanding your business. Every upgrade gives you another reason to open a pack.
Hire staff to help run the shop while you focus on your collection.
You can also use a compact window to keep the shop running in a corner of your desktop while you do other things.
It may not always be good business.
But there will be Grombos.
