Groundbreaking gameplay with IGT & Ultrahaptics

In November 2017 the SPHINX 4D™ game on the CrystalCurveTM TRUE 4DTM cabinet from IGT was deployed at Seminole Hard Rock Tampa, Florida – the first casino in the U.S. to launch the ground-breaking haptic gaming experience. In it, mid-air haptics was combined with glasses-free TRUE 3D™ and gesture recognition technologies to empower players to experience casino entertainment in completely new ways.

The search for pioneering player experiences

With over 12,000 employees, and customers in more than 100 countries, IGT is the world’s leading end-to-end gaming company. The company has a deep history of creating ground-breaking player experiences using pioneering technologies.

One of IGT’s many noteworthy product introductions came in 2013 with the launch of its TRUE 3D™ product line – a slot experience that brought glasses-free TRUE 3D™ gaming to the casino floor in its award-winning AXXIS™  3D video slot machines. Initially envisaged as a niche product, today there are over 3,000 TRUE 3D units in operation worldwide.

Design and development – creating a proof of concept

IGT’s R&D team and Ultrahaptics designed two possible scenarios integrating mid-air haptics with an IGT slot machine, and installed four demo units to present to IGT’s internal decision-makers. The demos proved that IGT’s existing TRUE 3D cabinets could be integrated with gesture recognition and Ultrahaptics’ technology to realize irresistible glasses-free TRUE 3D™ visuals that players can touch and interact with.

IGT’s TRUE 4D™ haptic video slot machines immerse players in the game like never before. Players can trace a sparkling butterfly shape in mid-air, feel the sparkles tingling their fingertips and then watch the butterfly come to life and fly away – just one of many gesture-controlled “secrets” within the game.


Once the project was greenlit, Ultrahaptics and IGT meticulously refined the technology integration. To achieve truly immersive gameplay, the glasses-free TRUE 3D™ graphics, haptic feedback, gesture recognition and content all needed to be seamlessly integrated.

Ultrahaptics’ ultrasonic transducer array was also adapted to ensure it was optimized for a casino environment, and the technology was customized to integrate it into IGT’s CrystalCurve™ TRUE 4D™  hardware and software platform.

Market launch

IGT’s Sphinx 4D game on the CrystalCurve TRUE 4D™ cabinet was first unveiled at the 2016 Global Gaming Expo (G2E). At G2E 2017, IGT unveiled additional TRUE 4D games, including globally celebrated licensed themes.

In November 2017, Seminole Hard Rock Tampa became the first casino in the US to have the SPHINX 4D™ game on its casino floor. IGT is now actively introducing the TRUE 4D™ gaming experience in markets around the world.

Awards and reactions

SPHINX TRUE 4D™ won the Global Gaming Award’s “Land-based Gaming Innovation of the Year” award in 2017 and widespread industry acclaim.

IGT’s collaboration with Ultrahaptics resulted in a unique multi-sensory experience that was not only new in casinos, but leveraged technology that is not yet commercialized in the consumer electronics space. The positive reception demonstrated the power of industry leaders, such as IGT, incorporating haptics into their products.
