In traditional games, players purchased in-game items through microtransactions to enhance their experience. However, these items could only be used within the game and had no real-world economic value. Even fully priced titles often included in-game purchases for character or weapon customization, and such monetization models have historically created a market valued at up to $65 billion.
Free-to-play games issue in-game currencies for monetization. For example, Roblox—with 43 million daily users—uses Robux as its exclusive in-game currency. These virtual currencies have long enabled players to enrich their gameplay.
The rise of NFT games has fundamentally transformed gaming economies. In NFT games, in-game items are issued as NFTs (non-fungible tokens), allowing players to genuinely own, freely trade, and exchange these assets. This innovation introduces the potential for players to earn real economic rewards.
NFT game economies are built on two key components:
Use of NFTs (Non-Fungible Tokens)
In-Game Token Economy
NFT games are fundamentally distinct from traditional games. Players are no longer just consumers—they become “owners” within the game economy, contributing to the ecosystem and potentially earning tangible rewards. This new model is driving innovation in the gaming industry and reshaping relationships between players and developers.
“Play-to-Earn” (Play-to-Earn) and “Tap-to-Earn” are innovative earning models powered by blockchain and NFTs that have attracted significant attention in recent years. These models underpin new economic systems in NFT and blockchain games, making the previously unthinkable concept of “earning while playing” a reality.
Play-to-Earn enables users to earn cryptocurrency or NFTs by playing games. In this system, in-game items and characters can be traded as NFTs and converted into real-world currency.
Examples and Key Features
By contrast, Tap-to-Earn offers a simpler, more accessible earning model. Users receive rewards for simply tapping apps or performing easy actions.
Examples and Benefits
These new business models are creating “earning” ecosystems that go beyond traditional games and apps. The appeal of earning rewards while having fun has made Play-to-Earn and Tap-to-Earn popular across diverse demographics and regions. As key concepts in the digital economy, they are expected to see continued growth.
NFT games are fundamentally different from traditional games. Players don’t just play for fun—they have the potential to generate real economic returns through gameplay. This innovation has evolved games from pure entertainment into “income-generating activities.” There are three primary approaches to earning in NFT games:
1. Monetizing NFT Trades
Players can sell in-game NFTs on dedicated marketplaces to receive cryptocurrency or fiat. NFT values fluctuate based on rarity, in-game usefulness, and the game’s overall popularity.
2. Earning Gameplay Rewards
Players can steadily accumulate tokens or NFTs through daily gameplay, building assets while enjoying the experience.
3. Leveraging the Play-to-Earn (P2E) Model
Many NFT games adopt the Play-to-Earn model, directly linking gameplay with cryptocurrency rewards.
NFT games attract global attention as a new genre enabling players to earn while having fun. However, due to risks such as market volatility and upfront investment requirements, it’s critical for participants to thoroughly research and fully understand the landscape before getting involved.
Axie Infinity is a Play-to-Earn (P2E) game inspired by beloved Japanese franchises like Pokémon and Tamagotchi. The metaverse platform runs on the Ethereum blockchain, leveraging NFT technology to represent unique characters, land, and other assets.
Launched in March 2018, Axie Infinity is recognized as a trailblazer that propelled the NFT gaming industry. The Vietnam-based team, led by Trung Nguyen and Sky Mavis, blended addictive gameplay with a robust economic system, making the game a genuine income source for many players.
The core gameplay of Axie Infinity centers on tactical, skill-based battles. Players assemble three fantastical creatures called “Axies” and engage in strategy combat. These Axies are issued as NFTs and can be freely traded on the marketplace.
Winning battles grants players “Smooth Love Potion (SLP),” a vital in-game resource. SLP is a tradable token used to breed and evolve Axies and is available on external exchanges, giving it real-world value.
Axie Infinity’s multi-billion-dollar economy is underpinned by three main digital assets:
Smooth Love Potion (SLP)
Axie NFTs
Axie Infinity (AXS) Token
Staking works much like a bank deposit—by locking AXS in a liquidity pool, players earn additional AXS rewards and help stabilize the ecosystem.
The total supply of AXS tokens is capped at 270 million, with 21% held by Sky Mavis for fundraising. For Play-to-Earn rewards, 20% of AXS is allocated over 4.5 years.
The Sandbox is a user-driven metaverse game platform powered by blockchain. Players purchase virtual land called “LAND” and engage in activities such as game creation, avatar customization, and item sales—playing, creating, and earning in a dynamic ecosystem.
The vast metaverse includes 166,464 LAND parcels, allowing players to interact globally and embark on diverse adventures. LAND owners can create unique games, place avatars, and set up original items to fully express their creativity.
A standout feature is the “Game Maker” tool, which lets anyone build 3D games—no programming required. This has lowered the barrier to game development and empowered more creators to realize their visions in the metaverse.

As a governance token, SAND has several uses:
Buying In-Game Items and Avatars
Buying LAND
Using Game Creation Tools

Staking for Rewards
SAND is essential for all economic activities—playing, customizing avatars, acquiring land, or trading assets. The token economy underpins The Sandbox’s sustainable ecosystem.

Core Gameplay
New players start with four free Gas Heroes. These can be used to build a base and engage in battles. As the game advances, players collect more heroes to form stronger teams.

Global artists like Ariana Grande, Travis Scott, Marshmello, and Justin Bieber have held virtual concerts here, boosting Decentraland’s prominence and showcasing the potential of metaverse events.

Industry experts and market research organizations offer a positive forecast:
Market Growth
New Forms of Entertainment

Technology and Usability Advances
Legal and Regulatory Progress
Governments and regulators are establishing NFT and blockchain laws, improving transparency and safety. Legal frameworks will encourage investment and healthy market growth.
Overall, NFT games have a bright future, driven by technological evolution, market expansion, and innovative business models.
Play-to-Earn (P2E) NFT games let players monetize in-game achievements as crypto assets or NFTs. Players earn rewards with real value by completing missions or acquiring items.
Players earn by collecting tokens through Play-to-Earn models or selling in-game NFTs. Tokens and NFTs can be sold on marketplaces, with earnings tied directly to playtime and market demand.
Initial investment varies by game and platform. Most require at least several thousand to tens of thousands of yen, and in Axie Infinity, players can expect to earn about 4,500 yen per month. Some games are free to start, but meaningful earnings typically require an upfront investment.
Main income sources are in-game tokens and selling NFT assets. The Play-to-Earn model rewards players with tokens and NFTs that can be sold to others on marketplaces for profit.
Axie Infinity, The Sandbox, Decentraland, Splinterlands, and Alien Worlds are leading examples. Players profit by selling assets or earning staking rewards.
If a game shuts down, item value may be lost. Prices are volatile, and reliance on new players can cause token values to crash. Beware of scams and counterfeit NFTs. Legal ownership is limited to usage rights, not property rights.
Gods Unchained and Crypto Spells are recommended. Both are free-to-play trading card games, easy for newcomers, and allow players to profit from card trading.
NFT game earning can be sustainable. The Play-to-Earn model enables trading NFT items and characters for profit. As the market matures and major companies join, long-term growth looks promising.
NFT games give users direct control over in-game assets, while traditional games’ assets are lost if the service ends. Blockchain technology ensures secure transactions, resists cheating, and allows players to earn through gameplay.
With the right skills and effort, earning around 100,000 yen per month is realistic. Choosing the right games and managing playtime can further boost earnings.
