Bid King is an auction and collection game built for World App. Enter auction rooms, compete for sealed crates, reveal collectible items and grow a collection spanning cities and cultures.

Auctions
Every auction requires one ticket. Location and time determine the loot pool, bidder behavior and pacing; auction mode determines the bid currency.
Standard Auction
Bids use Coins and a 5% auction fee. Intended as the primary progression loop.
Advanced Auction
Bids use bidWLD. Each crate has a fixed average EV of 1.000 bidWLD, with bids from 0.100 to 2.000 bidWLD and no auction fee.
Fast Auction
Optional mode that reduces the crate timer from 30 seconds to 15 seconds. It changes pacing only and does not improve item odds.
Items, Rarity & Condition
The catalog contains 480 items. Each has a base value, category, rarity and condition. Rarity tiers are White, Green, Blue, Purple, Gold and Red. Conditions are Worn, Good and Mint and affect true value. Every Location has one exclusive Red item outside Collection Sets. Red items cannot be sold directly from Inventory: they must be appraised and sold through Dark Market, with values and offers displayed in bidWLD. Cosmetic rewards never increase drop rates or bidding odds.
Collections
Discover every required item to complete a themed set. The current build contains 17 sets: 13 Standard and 4 Advanced. Standard sets award Coins, while Advanced Red-item sets award bidWLD. Both can unlock the listed profile cosmetic, title, avatar or frame.
Market
System Store
Four White–Gold items rotate each UTC day. Prices range from 70% to 160% of base value, and each slot can be purchased once per account per day.
