According to WeChat public account @DappReview, on October 14, the blockchain game Cheeze Wizards was on the Ethereum main online line. In less than 24 hours, the player @samczsun told the official that there is a serious bug in the game contract, and using this bug can make the player invincible. Cheeze Wizards then decided to use a forked solution to protect the user's rights. Cheeze Wizards has now fixed this bug and deployed a new smart contract. The 178 ETH lost in the prize pool has also been added, but Cheeze Wizards has not closed the problematic game, but has made it a hacker.
