Exhibit 99.1

Email to Employees – BYI/SHFL Update

October 21, 2013

Dear SHFL Team,

In keeping with my commitment made to you during our Town Hall meeting, I want to update you as to the status and ongoing activities related to the pending acquisition of SHFL entertainment (SHFL) by Bally Technologies (Bally). Because of the many Securities and Exchange Commission (SEC) regulations we have to follow as a result of going through this process, there are many restrictions that affect what we can communicate – both internally and externally. I thank you all for being patient and diligent in light of these limitations, and I am especially appreciative of your tremendous efforts and hard work these last few months. I know it’s not easy to stay focused in the face of change and you all have done a terrific job continuing to make this company successful each and every day.

Together, SHFL and Bally are making significant progress toward planning for the closing of the acquisition and integrating the two companies. One of the important steps leading to the closing of the transaction is obtaining approval by the appropriate gaming regulatory authorities. On September 23, 2013, an amended preliminary proxy was filed with the SEC, which included an update on Bally’s progress in obtaining the requisite gaming approvals. At the time of that filing, and currently, Bally had obtained gaming approvals in 14 of the approximately 20 gaming jurisdictions required for closing. As a result, new timing was anticipated for closing of the deal. Previously, the timing was expected on or before June 2014. The amended filings presented a new anticipated close date on or before December 31, 2013, subject to the approvals of SHFL shareholders as well as other customary closing conditions.

The next significant milestone in this process is obtaining shareholder approval, which means we must receive a majority vote from our shareholders on approving the transaction. The voting window will officially close at a Special Meeting of Shareholders. On October 10, 2013, a notification was filed with the SEC stating that November 19, 2013, would be the date of the Special Meeting. On October 16, 2013, our definitive proxy statement was filed with the SEC and mailed to our shareholders. Attached you’ll find a timeline of the key acquisition milestones mentioned above. After the Special Meeting on the 19th, we will be having an Employee Appreciation Celebration at our campus to thank everyone for their contributions to SHFL’s success over the years. We will send an email with more details on this event in the coming weeks.

Over the past few weeks, you might have noticed Bally team members onsite at the SHFL campus, and vice versa. Integration-planning discussions between the management teams of SHFL and Bally are currently underway with the objective of building and implementing successful transition plans. In the last 30 days, there have been two offsite sessions led by the Integration Management Office (a team comprised of both Bally and SHFL representatives) where the departmental planning teams have come together to identify action items and provide status updates in their respective areas. These sessions focused on identifying key integration tasks pre and post closing, including a discussion of Day One (date of close) deliverables and preparing for near-term milestones for the first several months after close.

Ramesh Srinivasan, the CEO of Bally, and his team have been deeply engaged in learning about SHFL’s unique businesses and have expressed strong appreciation and respect of our people and our culture. We’ve invited Ramesh to make a Town Hall presentation to our team where he will provide more information about Bally’s business and culture, and discuss how SHFL is an exciting part of the story moving forward. We will email everyone with more information on this event this week.

Last, but certainly not least, I would like to thank you for another successful G2E; in my opinion, our best one yet and a shining example of why SHFL sets the bar so high. It was an emotional week for me compounded by the fact that the team put on the most exciting and high-energy presentation that we’ve ever delivered in our history. To watch our team in action – on top of their game and laser-focused on the customer and on each other – was truly inspiring and something I will never forget.

Thank you again for your diligence and focus during this busy time of transition. I ask that we continue executing at the highest level, ensuring that we are poised to succeed and keep the momentum going.

Kind Regards,

Gavin Isaacs
