Gacha Machines
A gacha machine is a randomized distribution mechanism, often used in gaming and collectibles, where players spend currency or points for a chance to receive a random item
1. The concept is similar to opening a pack of trading cards, where the specific contents are unknown until the "gacha ball" or pack is opened

Core Mechanics
- Randomization: Outcomes are determined by chance and are not influenced by player skill .
- Acquisition: Players typically purchase spins or "balls" using in-game tokens, points, or staked assets 1.
- Rewards: Machines are loaded with a set of items, such as NFTs, cosmetic items, or power-ups, which vary in rarity 15.
- Supply Constraints: In some ecosystems, gacha machines have limited inventory. High demand can lead to "supply exhaustion," where the machine stops functioning until more items are added 6.
On-Chain Gacha and Web3 Integration
The use of gacha mechanics has expanded significantly within blockchain gaming and NFT marketplaces.
Market Growth
On-chain gacha volumes experienced explosive growth in 2025, with projections reaching $600 million for the year

Implementation Examples
- Fren Pet: Players acquire points through staking tokens or winning battles to unlock Gacha Machine spins . These spins can result in earning or losing points (AP/DP) .
- Doki Doki: This platform allows users to deploy their own "Gacha Factory" machines without coding, loading them with NFTs for others to play 1.
- Faraland: Uses a gacha machine to distribute limited-edition items of special rarities, often available only during specific events 5.
Spending Patterns
Data from platforms like Collector Crypt shows that players often favor higher-tier options, such as "Legendary Packs," over cheaper "Elite Packs," leading to massive spikes in spending when supply is available
