Slab City is a free browser-based card trading simulation game. You have 30 in-game days to buy, sell, grade, and collect cards across 9 different locations to maximize your net worth.

How do I make money in Slab City?

Buy cards when prices are low, sell when prices rise, get valuable cards professionally graded to increase their value, open raw and graded packs for rare finds, and bid at auctions for underpriced items.

What is card grading in Slab City?

Card grading sends your card to a grading service. If the grade comes back high (Gem Mint 10), the card value increases significantly. Grading costs money and takes in-game days, so choose cards wisely.

What is the Daily Challenge?

The Daily Challenge is a seeded game where all players share the same market conditions and card prices. Complete it every day to climb the leaderboard and build your Total Haul.

Is Slab City free to play?

Yes! The Daily Challenge and Story Mode Act 1 are completely free. A one-time PRO upgrade unlocks unlimited free play, full story mode, friend challenges, price charts, and additional card skins.

How do Friend Challenges work?

Friend Challenges are 24-hour head-to-head games where you and a friend play the same seeded game. The player with the higher net worth at the end wins.

What card skins are available?

Slab City includes Sports, TCG, and Combined skins for free. PRO members can purchase additional skins: Video Games, LOTR, Unpocketable Monsters, Tennis, and Coins — each $2.99.

Story Mode is a 22-chapter campaign where you follow a narrative through the card trading world. Each chapter has unique objectives, choices that affect the story, and optional bonus objectives.

Grading costs scale with the card's value: standard is 10% (min $25), 3 days; express is 20% (min $50), 1 day. A grade can make or break a card — it's a gamble worth taking on your best pulls. (Some skins relabel the scale, but the math is identical.)

✍️ AUTOGRAPH

Once per game (unlocks at $150K) sign one raw card for a +80–120% boost. Stacks with grading.

🎯 SETS

Complete themed card sets for a +20–40% portfolio bonus.

⚠️ WATCH OUT

Counterfeits — cards from yard sales, storage, and online can be fakes. They're caught and confiscated during grading. Sealed and graded packs, the card shop, and already-graded slabs are always real.

Loans — you can borrow $10K or $20K, but interest compounds at 5% a day. Debt eats your net worth, so pay it back fast.

The market moves — news events swing whole categories up and down. Buy the dip, sell the spike.

🎮 WAYS TO PLAY

🕹️ Free Play — pick a skin and go. Choose Casual (relaxed: more cash, no fakes) or Normal (the standard ruleset).

🏁 The Chase — flip the toggle in Free Play to race for a full collection instead. Own every card in the skin; fewest days wins.

⚡ Daily Challenge — everyone plays the same seed plus a rotating daily twist. One attempt a day, ranked on the daily leaderboard.

📖 Story Mode — a narrative campaign across chapters, chasing your father's lost collection.

🎲 As you play, minigames pop up — pack gauntlets, haggling, casino blackjack, grading shifts. Practice any of them risk-free in the Arcade.

⭐ Every finished run feeds your lifetime Total Haul — leveling you up and unlocking 25 collectible persona titles. Play friends head-to-head with friend codes.

💡 FAST TIPS

🏷️ Buy at yard sales — prices are a fraction of market.

📦 Storage lots are a secret weapon for crazy pulls.

🏆 Grade your best cards — a SCG 10 can 3.5× your money.

📰 Ride the news — events create buy-low / sell-high windows.

💰 Don't let debt snowball — 5% daily compounds fast.
