What Is Play-to-Earn? How Blockchain Games Work
Play-to-earn games reward players with tokens and NFTs that can be traded. Learn how blockchain games work, where rewards come from and the risks involved.
For decades, the coins, skins and rare swords you earned in video games stayed locked inside those games. Play-to-earn (P2E) games changed the pitch: what if those items were yours, could be sold to other players and had real-world value? This guide explains what play-to-earn means, how it works and why it has been both exciting and controversial.
The basic idea
A play-to-earn game uses a blockchain to represent some in-game assets. Typically that includes:
- Fungible tokens — in-game currencies or rewards that can be traded on crypto exchanges.
- NFTs — unique items such as characters, land, weapons or cosmetics that players hold in their own wallets. See NFTs in games explained.
Players earn these assets by playing — completing quests, winning battles or breeding characters — and can sell them to other players. In theory, time spent playing turns into tradeable value.
How it differs from traditional games
| Traditional games | Play-to-earn games | |
|---|---|---|
| Item ownership | Licensed to you by the publisher | Held as tokens in your wallet |
| Trading | Often restricted or banned | Open marketplaces |
| Real-world value | Usually none officially | Market-driven, often volatile |
| Entry cost | Game price or free-to-play | Free, or upfront NFT purchase |
| Main risk | Losing time | Losing time and money |
A short history
Blockchain games appeared soon after Ethereum launched. CryptoKitties, a 2017 game about collecting and breeding digital cats, became so popular that it congested the Ethereum network. The play-to-earn label went mainstream in 2021 with Axie Infinity, where players battled and bred creatures called Axies. At its peak, some players in countries such as the Philippines reported earning more from the game than from local jobs.
That boom didn't last. Token prices fell sharply as the game's economy came under pressure, and in March 2022 the Ronin bridge connected to the game was hacked for roughly $600 million worth of crypto. The episode taught the industry hard lessons about sustainable game economies and security.
Where do the rewards come from?
This is the most important question to ask about any P2E game. Rewards usually come from:
- New players buying in — purchasing NFTs or tokens needed to play.
- Token issuance — the game creating new tokens as rewards.
- Spending by players — on upgrades, cosmetics or fees.
- Investors and treasury funds supporting the economy for a time.
If most rewards depend on new players arriving, the economy can behave like a pyramid: it works while growth continues and struggles when growth stops. We explain this in why play-to-earn rewards often fall.
What you need to play
- A crypto wallet compatible with the game's blockchain. Use a separate wallet, not your savings wallet.
- Sometimes, starter NFTs — characters or items you must buy or borrow.
- A small amount of the network token to pay transaction fees, unless the game covers them.
- Time — often more than you'd expect to earn anything meaningful.
The risks
- Falling token prices can make earnings shrink quickly.
- Upfront costs for NFTs may never be recovered.
- Security — fake game sites, malicious mints and wallet drainers are common. See crypto gaming scams.
- Project risk — developers can abandon games, leaving assets worthless.
- Regulation and taxes on earnings vary by country.
Warning: Be cautious of any game that requires a large upfront purchase and promises a fixed daily income. That combination has historically led to heavy losses.
Where the industry is heading
Many studios now describe their games as "play-and-earn" or simply as games with player-owned assets, putting fun first and earnings second. You can read more in play-and-earn vs play-to-earn.
Frequently asked questions
Do I need to buy crypto to play blockchain games?
Not always. Many newer games are free to start and some don't require a wallet until you want to trade. Older play-to-earn games often required buying NFTs first.
Are play-to-earn earnings taxable?
In many countries, tokens earned from games can be treated as income, and selling them may create capital gains. Keep records and check local rules.
Which blockchain do games use?
Games run on many networks, including Ethereum layer-2s and other chains chosen for low fees and speed. Always confirm the correct network before sending any tokens to a game wallet.
Key takeaway
Play-to-earn games let players own and trade in-game assets on a blockchain, which creates the possibility — not the promise — of earning. Ask where rewards come from, start without large upfront costs, use a separate wallet, and play games you'd enjoy even if the tokens were worth nothing.
