On Wednesday, casino gaming equipment maker SHFL entertainment (UNKNOWN:SHFL.DL) announced that it has acquired Chinese electronic gaming maker ProTec Games for an undisclosed sum.

In a statement on the acquisition, SHFL Chief Executive Officer Gavin Isaacs noted that SHFL has worked with ProTec over the past year, hiring the company to develop software for is slot machines and other electronic games, and has "been very happy with their work."

Happy enough to buy the whole company, apparently -- and investors seem happy as well. In response to SHFL's announcement, they bid up the company's shares 3.7% to close at $16.01.
