Casino operators aren't the only ones cashing in on expanding gaming around the world. Gaming equipment makers have had a great year on the back of gaming growth as well.

As operators from Asia to Kansas City grow casinos, their floors need to be filled with tables, slot machines, and chips. Casinos like the one recently opened at Kansas Speedway by Penn National Gaming (Nasdaq: PENN) have been popping up around the country, and innovative games are how they get consumers to play.

A quarterly overview
At slot maker Bally Technologies (NYSE: BYI), calendar fourth-quarter revenue grew 15% to $210 million on strong growth from gaming equipment, operations, and systems. Adjusted EBITDA increased 18% to $67 million, which helped drive a 10% increase in earnings per share to $0.54.

Table game and shuffler maker Shuffle Master's (Nasdaq: SHFL) revenue increased 12% to $65.7 million and earnings increased 80% to $0.18 per share. The company's leasing, royalty, and service revenue now account for 42% of revenue after some tough years making a strategic change to push these products.

International Game Technology (NYSE: IGT) saw revenue decline 1% overall to $446 million in the most recent quarter but international sales are starting to pick up. International revenues jumped 24% from last year to $123 million due in part to increased leases in Latin America.

WMS Industries (NYSE: WMS) was the one player that saw its results decline. In the last quarter, revenue fell 23.3% to $97.5 million. But the company experienced a $10.4 million increase in revenue on a sequential basis as shipments improved from the previous quarter.

The best bet from here
I think Shuffle Master is the best pick among these stocks because some of its products have less fierce competition than slot makers. The company has also been successful at increasing recurring revenue consistently over the last two years. With gaming expansion continuing to take place in Asia, where table games are more prevalent, the company should continue to profit.
