If noted, Jackpot size in slot machines is indicated without currency. This is done because players make bets in their currency, and accordingly, gain winnings in this currency.
Suppose Mega MoolAh accumulates in pounds, and the player won in dollars. The difference is significant, especially if we consider millions. 10 million in pounds are now equal to about 12.71 million in dollars.
In this case, If a player breaks off a jackpot in dollars, then the remaining difference in 2.71 million dollars added to the initial amount of jackpot. Therefore, initially no 1,000,000 appears on the balance sheet, and more. That is why immediately after breakdown, the jackpot there can be condicted incredible amount.
In fact, I do not know what currency Moolah, pounds and dollars are copied only for example.
