Johannesburg - SA had the fastest-growing casino market in 2010 with a 3.5% increase, PwC said in its Global Gaming Outlook to 2012 released on Monday.
"Going forward, casino upgrades and a new casino licence will enhance the South African casino market, but compared with the prior decade - when a number of new casinos opened - there will be relatively little growth from new casinos during the forecast period."
A new 15% tax on winnings of R25 000 or higher, provisionally scheduled to go into effect in 2012, was expected to have an adverse impact on the market.
However, there were currently no details available on how the proposed tax was to be calculated or collected, the survey found.
