Decentralized applications (DApps)
A software that communicates with a blockchain and integrates with them through smart contracts. These applications can look like ordinary applications, and can take the form of web applications, desktop applications or mobile apps.
When they store the information on a blockchain and perform calculations with smart contracts, they are also unstoppable. If someone finds them inconvenient, it is not possible to take down any servers to get rid of them. There are also no middlemen and they do not require you to trust the organization or company behind the applications.
Today, decentralized apps are still somewhat limited as most are based on Ethereum, which can only handle about 15 transactions / events per second. This has not significantly hindered development, and will be resolved with Ethereum's transition to Proof of Stake and newer, more modern blockchains.
See a top list of decentralized applications on DappRadar and State of the Dapps.
Games
Alien Worlds
A NFT-based game on the WAX blockchain. You can buy, sell, trade NFTs and participate in planitary organizations (DAOs).
SpliterLands
A card game where you collect cards, where some are more or less unique. These cards can then be exchanged between players in a marketplace, or played with. The game can be seen as a mix between pokemon playing cards and World of Warcraft. The game runs on the blockchain Hive.
My Crypto Heroes
A turn-based RPG game that runs on both mobile platforms and desktops. It is about finding, saving and training heroes from history. A hero is stored on the blockchain and can of course not be copied.
CryptoKitties
Perhaps the most famous DAPP, although it is not the most popular anymore. Here you collect cats - decentralized cats, that is, stored on the Ethereum chain. Cats are mated with other cats and since each cat has a simple DNA, the offspring will be a result of this DNA. Every cat is unique.
