Games using non-fungible tokens allow players to earn cryptocurrency on the gameplay by selling received game items, grown pets or digital collectibles through special exchanges. The market for tokenized objects is growing every day. Entire metaverses based on NFT technology are developing. Mark Zuckerberg renamed the Facebook corporation to Meta and plans to develop his virtual tokenized world. The launch of its own NFT marketplace in December 2021 was announced by the Ubisoft studio, a giant in the video gear industry. All this means that the topic of NFT in gaming is more relevant than ever.
In this article, we will look at the most interesting NFT games and talk about the industry as a whole.
A bit about Blockchain
NFTs are based on blockchain technology. To give a simple analogy, the blockchain is the lines in copies of the “account book” stored on different computers and containing information about transactions. Entries in these “lines”, or blocks, cannot be changed without the consent of other participants – the owners of the “book”. There is no “main controller” in the blockchain – all actions are performed in a decentralized manner. This approach provides security, because in a distributed network it is impossible to hack one specific computer to erase or change all information.
To control the correctness of new records in the network (that is, transactions made), large computing power is required. They are provided by the computers of the miners. With the help of special software, they solve cryptographic problems, thereby confirming transactions.
Blockchain game development is a more complex topic. It involves crypto exchanges and special “smart contracts”.
How smart contracts are used in NFTs
To put it simply, a smart contract is a piece of code that works under certain conditions, establishes the order of interactions between users and ensures the transparency of transactions in the blockchain network. Some smart contracts make it impossible to replace one original token with another, as if assigning it a “certificate” with a set number. Yes, the cryptocurrency also has a conditional “serial number”. However, it is interchangeable. In this regard, bitcoin is like a dollar (one piece of paper is equal to another), and an NFT token is like a collectible card or paper with ownership of a house (the value of each object is not equivalent, and ownership is officially assigned to the owner). Due to their properties, non-fungible tokens began to be used to sell digital works of art – paintings, photographs, sound recordings.
How NFTs are involved in games
Let’s get back to the main topic – NFT games for Android, iOS and PC. The use of new technologies has complemented the classic monetization schemes in the gaming industry and added new ones. Game-fi is based on cryptocurrency settlements and securing ownership of virtual items through NFT. Game projects on the blockchain allow users to earn income in several ways.

Play to earn. Users get items, develop characters, master game territories – just like in regular games. But when using NFT, a virtual helmet or a house becomes a unique object, a “single copy”, the ownership of which can be sold on a crypto exchange. Neither game developers nor other users will be able to take away the token without the consent of the owner. With this monetization model, the more time and effort a player spends, the more profit he gets. Most often, NFT games on iOS and Android are built according to the play-to-earn scheme.
Why NFT in games has become popular?
The possibilities of blockchain technology bring a number of advantages to games.
Now players are less dependent on the developer. An item protected by a token cannot be simply taken away or drastically reduced in price by stamping a hundred similar ones. The value of the conditional magic NFT sword is only lost if the game completely stops working.
In theory, one item with NFT can be used in different games and traded on all available crypto platforms, and not on special marketplaces. Many players would like to slash enemies in Skyrim with their favorite sword from Dark Souls.
Original use cases
Tokenization is not only about trading in virtual rarities. NFTs are already becoming part of the gameplay. In the CryptoKitties game, users are encouraged to raise crypto kittens by crossing the cats of the “parents”. Due to the NFT smart contract built into the code of the game objects, the offspring receive a unique appearance that depends on the “genome” of their ancestors.
