Yu-Gi-Oh Pack Playground
Custom Grev.dad pack opening mode powered by YGOPRODeck card/set data for art + card metadata, with Grev.dad controlling the economy: Grev Coins, pack prices, rarity odds, sell-back values, inventory, achievements, missions, and streak bonuses. No cash-out, no real-money trading, pure collection energy.
Open packs
Every pack has 5 cards with a guaranteed Rare slot. The other four slots use Grev.dad rarity tables.
Single-card opener
Pull one card from the full database for a fixed admin-set price.
Your collection
Collection-only inventory with Grev.dad sell-back values and foil labels.
Card pricing + rarity data
Estimated Grev Coins pricing generally mirrors online demand; if no dependable value is available, Grev.dad stores a fallback estimate.
Achievements, missions, and streaks
Grev.dad controls coin rewards so you can tune progression independently from card metadata.
