An online casino player is richer to the tune of $22,500 thanks to Liberty Slots and a session on its Cash Cow slot from developer Wager Gaming Technology Software.Known as ‘Rachel C’, the California resident tried Cash Cow soon after it was released in January and got lucky by entering the barnyard and hitting the game’s pick-me bonus game.“There's so much going on in this game [and] so many different ways to win [that] I wasn't really sure what happened,” said ‘Rachel C’, who listed games including Amanda Panda and Agent Cash as previous favorites.“All of a sudden I'm picking the milk jug option and then there are bells and lights and $22,500 extra in my account. This is definitely the best new game I've seen in a long time [and] so much fun. This windfall is going to come in really handy. We've always talked about a trip to Hawaii and this may finally make that dream come true.”
