Summary
Steal a Card Pack is an 8-player Roblox game about collecting, opening and stealing trading-card packs, with original art for every card and pack, a full progression system, and its own advertising pipeline.
The pitch
Rip it. Guard it. Steal it.
Packs roll out of a factory on a conveyor. Buy one and it goes to a pedestal in your shop, earning cash while it stays sealed. Open it and the cards earn forever. Leave it unguarded and someone will grab it and run.
Owners catch thieves by touching them, everyone carries a Slap Glove, and every successful steal raises a bounty over your head.
Original card art








Every card and pack has its own artwork. Move across a card to catch the foil.
The loop
Seconds, minutes, hours, weeks
- Seconds
Grab, rip, slap
Card flips with mutations and NEW badges, flying cash, and a chunky Slap Glove with a swoosh on every swing.
- Minutes
Shiny packs and server events
Gold, Diamond and Rainbow packs, plus events like Pack Rain, Heist Hour and the Mythic Meteor every few minutes.
- Hours
Challenges and the Collector Pass
Daily and weekly challenges, a 30-tier pass, upgrades, Trade-Up and brand sets.
- Weeks
Rebirths and leaderboards
Rebirth milestones that unlock permanent perks, 66 achievements, 30 titles and God Pack hunting.
- Always
A next goal on screen
A slim card that always picks the most useful next thing to do, with a GO button that points at it in the world.
- Fair
Server-side checks
Guards against teleport and speed-hack steals, remote buying and fake pass purchases, and saves and purchases protected through DataStore outages.
Marketing
Thumbnails and ads
Ads made with a toolkit built for the job: real avatars posed and shot in Roblox Studio, cut out from white and black captures, then composited with outlined type and drawn faces.
Development highlights
Code first, place second
The whole game lives as source files. A build script writes the scripts into the place file and leaves map edits alone, so Studio and the repository stay in sync.
- Phone, tablet and desktop layouts that avoid the Roblox top bar, thumbstick and jump button
- Yearly Halloween event with its own shop, mutation and lighting
- SourceServer, client and shared Luau modules in src/
- BuildPython tools write scripts into the place and checksum Studio against source
- TestsThe real server and client code runs headlessly in a mock Roblox runtime
- EconomyA pacing simulator sets prices so a new pack tier unlocks about every five minutes
- NetworkTraffic cut by about 93% in the v3 pass
