EOS Fancy Guessing Game Suspected of Stolen Hundreds of EOS

Last night (January 1) at 21:30, the EOS fancy guessing game was suspected to have been stolen by the EOS account liuliangyi22 with hundreds of EOS. The hacker won every time he bet. The game contract used two delays and took the block hash as the seed, and there was no rollback. The game contract has been frozen and the reason is being investigated. Game developers and game players need to be vigilant about security risks. (IMEOS)
