Slot machines were banned by the government in late 2012, leading to speculation that the government was planning to sell lucrative gambling concessions. Only seven concessions were granted. The other two went to another well-connected businessman, who operates outside the Budapest region.

Vajna owns Las Vegas Casinos Kft, which reported turnover of 3.9 billion HUF in 2012. The law establishing the basis for concessions was introduced on a Sunday at the end of 2013 and quickly passed the next day. The concessions are expected to add 1 billion in VAT revenues to the national budget. The concessions cover a ten-year period. Critical news sources have questioned the opaque structure of both the process of granting the concessions and the ownership structure of Las Vegas Casinos Kft.
