Sell mystery boxes, blind boxes, gacha & bundle box campaigns that gamify shopping. Pick a product pool with auto-calculated odds, or group items into rarity tiers with set drop rates and turn overstock or bestsellers into surprise boxes. Customers see tier odds, then unbox online with animations, solo or in batches. Stand out with buyback: shoppers resell unboxed items at a trading price, driving repeat purchases. Track results with built-in analytics. Perfect for TCG, toys & seasonal sales.
