About Slab City
BUY LOW. SELL HIGH. GET GRADED.
Slab City is a free browser-based card trading simulator. Over 30 in-game days, you buy, sell, grade, and collect cards across 10 unique locations — chasing market swings, hunting grails, and building the most valuable portfolio you can.
Think of it as a retro terminal game meets the real thrill of the collectibles hobby: sports cards, TCG, vintage video games, coins, and more — all wrapped in a CRT aesthetic with chiptune audio and zero pay-to-win mechanics.
Every skin plays identically — same mechanics, different universe. Start free with Sports, TCG, or Combined. PRO members unlock:
Slab City is an indie project built with Next.js and Supabase by a solo developer who loves both retro games and the card hobby. No ads, no loot boxes, no pay-to-win. A one-time PRO upgrade unlocks the full experience if you want it.
