On October 30, it was reported that after Nintendo took action, an unlicensed game on 1Up, an NFT betting platform using the image of Super Mario, has been deleted from YouTube. It is understood that 1Up uses copyrighted materials, including the classic Mario Bros (Mario Elf), in a multiplayer platform game, which allows people to compete with their own NFT to obtain cash packs in the game. In a blog post in September 2021 (discovered by Kotaku), 1Up even claimed to “bring Mario and friends to the blockchain”, although it did not get the explicit participation or consent of Nintendo.
