Background: Duro Dogs is the first game on the NFTY Jigs Platform, where each dog is a unique NFT. Players can train, level up, and collect rewards, with every dog and item being tradable assets.

Problem: Because NFT assets often come in many variations, players found it difficult to recognize rarity tiers. This lack of clarity led to confusion, reduced engagement, and a weaker perception of value, ultimately impacting sales.

Solution: Working with the Design Lead, I developed a color-coding system that mapped dog tiers to distinct visual palettes. Common, rare, and ultra-rare dogs were defined by clear dominant and secondary color rules, making each tier instantly recognizable. This system streamlined player understanding, improved categorization, and enhanced the marketability of NFT assets, while also strengthening retention by making rarity feel more rewarding and collectible.
