There are several factors to consider. Some online casino game titles like Mega Moolah come with 4 jackpots. One of the Mega Moolah counters is the ‘mini’, which pays out every 20 seconds, while the top counter ‘Major’ displays millions of Euros or Dollars and pays out a millionaire’s windfall every 30 to 40 days. This is because it is a networked jackpot system with multiple slots. On the other hand, stand-alone versions pay out their big wins far less often. Usually around 2 or 3 times per year.
