Slot machine makers often look at the latest popular topics to get ideas for the themes of their new slot games. With Poker being so hot these days it was only a matter of time to see a slot game based on the World Series od Poker.

Harrah's Entertainment Inc. licensed the World Series of Poker brand to slot machine maker WMS Industries Inc. for use in video poker and slot machines.

The machines will be introduced at Harrah's casinos starting in the third quarter, the companies said in a statement. The games will be available later at other casinos, the companies said.
