This paper reports the results of a user trial with a slot machine equipped with a stereoscopic display. The main research
question was to find out what kind of added value does stereoscopic 3D (S-3D) bring to slot games? After a thorough
literature survey, a novel gaming platform was designed and implemented. Existing multi-game slot machine "Nova"
was converted to "3DNova" by replacing the monitor with an S-3D display and converting six original games to S-3D
format. To evaluate the system, several 3DNova machines were put available for players for four months. Both
qualitative and quantitative analysis was carried out from statistical values, questionnaires and observations. According
to the results, people find the S-3D concept interesting but the technology is not optimal yet. Young adults and adults
were fascinated by the system, older people were more cautious. Especially the need to wear stereoscopic glasses
provide a challenge; ultimate system would probably use autostereoscopic technology. Also the games should be
designed to utilize its full power. The main contributions of this paper are lessons learned from creating an S-3D slot
machine platform and novel information about human factors related to stereoscopic slot machine gaming.
