# Markets

One of the key differences between Tetris and other casual games is that nearly all the assets you earn from the game belong to you.&#x20;

Assets in Tetris mean almost everything you get in the game, Tetris, TETs, VSYS, tickets, etc.&#x20;

Players have full rights over their assets, such as trading them with other players, gifting them to friends or even destroying them without permission from the game or the development team. The market is the center for users to trade assets.&#x20;

Players can freely purchase game assets such as NFT cube people from other players, and can also sell their own NFT cube people.&#x20;

The Tetris market smart contract automatically collects service fees and royalties (collected in the form of TET tokens) from buyers and sellers who purchase NFTs in the market.
