Koi Princess was to be released on 24th November but was released by William Hill Vegas on 10th November. Although exclusive releases are nothing new, this was the first time Net Entertainment had released a game early via William Hill.  Koi Princess is available on desktop, mobile and tablet devices and is by far one of Net Entertainment’s largest endeavors so far. There are four randomly triggered features and four bonus features. koi princess william hill
