BALLY TECHNOLOGIES’ SYSTEMS SOLUTIONS TO POWER ‘WORLD’S LARGEST SLOT TOURNAMENT’ RECORD ATTEMPT AT MOHEGAN SUN APRIL 27

LAS VEGAS, April  23, 2013 — Bally Technologies, Inc. (NYSE: BYI), a leader in slots, video machines, casino-management, interactive applications, and networked and server-based systems for the global gaming industry, today announced  the innovative and award-winning iVIEW Display Manager™ (DM) with Elite Bonusing Suite™ (EBS) will power the quest for a pair of GUINNESS WORLD RECORDS® achievements at Mohegan Sun in Uncasville, Conn., Saturday, April 27.

Bally and Mohegan Sun have partnered to pursue world records for “Largest Slot Tournament” and the “Most Slot Machines Running the Same Game Simultaneously.”  More than 5,000 people are estimated to participate in the event

The tournament will include two heats  --  9 a.m. and 10 a.m. − throughout Mohegan Sun’s three casinos: Casino of the Earth, Casino of the Sky, and Casino of the Wind. Prizes will be awarded to the top 200 winners with $100,000 up for grabs and the first-place winner walking away with $50,000 cash. Guests can register that morning beginning at 7 a.m. in The Wolf Den club located in Mohegan Sun’s Casino of the Earth.

“This is another huge moment for Bally Technologies,” said President and Chief Executive Officer Ramesh Srinivasan. “The GUINNESS WORLD RECORDS events showcase our ability to deliver a tremendous return-on-investment to our casino partners. Similar EBS events have been proven to increase coin-in, time on device, carded play, and new player’s card signups. Working with a world-class casino like Mohegan Sun only further displays the power of iVIEW DM with EBS to create electrifying levels of anticipation and excitement across the casino floor and drive thousands of people to the casino resort.”

With Bally’s iVIEW DM and DM Tournaments, any machine with the technology installed, anywhere on the floor, can be turned into a tournament game and then turned back to normal game-play mode right afterwards. The technology enables casino operators to remove under-performing games from the floor, rather than retaining them just for tournaments. During The World’s Largest Slot Tournament attempt at Mohegan Sun, more than 3,000 games will be switched from normal playing mode to tournament mode and back within moments.

“This is going to be a great day for our property,” said Mohegan Sun President and Chief Executive Officer Bobby Soper. “We are thrilled to be working with Bally Technologies to provide our valued guests a one-of-a-kind event that will certainly bring a tremendous amount of entertainment to our players and excitement to the casino.”

Representatives from GUINNESS WORLD RECORDS will be at Mohegan Sun to validate the records.

Bally and Pechanga Resort & Casino in Temecula, Calif. previously set these records when 2,885 players competed in a slot tournament at the Southern California property in February 2012.
