G5 Electronic Roulette (Diamond Generation)
Double-sided overhead signage and “00” wheels · confirm quantities available
A fully automated wheel ringed by player stations, with no dealer needed. Compressed air launches the ball onto the rim and three sensors read where it lands, so results come back quickly, and the wheel changes its own balls from a magazine of ten. The rim is carbon fiber that will not flex, and Interblock builds in protection against simultaneous betting and against phone apps that try to predict the wheel. Diamond Roulette comes with single- or double-zero wheels; one of the systems we listed is a double-zero unit with two-sided overhead signage.

About Interblock
Joc Pečečnik got started in 1989 in Mengeš, a town just north of Ljubljana, assembling PCs and then point-of-sale systems for bars and restaurants. In 1997 he and a team of five, working out of his garage, built Princess, an automated roulette that let several players bet at their own stations around one wheel, and took it to the ICE show in London.
Interblock grew one generation at a time. Queen and Supernova followed in 2000, Stardust in 2001 with a touchscreen at each seat, and later lines added crystal-trimmed cabinets, a mechanical card generator for blackjack and the Organic range. The fifth generation, marketed as Diamond and shown at ICE in 2014, is the G5 family sold today. GGB credits the company with helping to bring automated roulette to European casinos in the 1990s.
In June 2022 funds managed by Oaktree Capital bought the company. Chief executive John Connelly, who joined in 2015 after 11 years at Bally Technologies, stayed on. Interblock is still headquartered in Mengeš and has a U.S. office in Las Vegas.
