The leading American facing software provider Realtime Gaming (RTG) has introduced a new and innovative jackpot feature which is appropriately termed Boiling Point Jackpots. As water is heated at first there is no visible sensation. But as the temperature approaches boiling point, the activity erupts and the water is seen to bubble with fast increasing ferocity. Exactly the same thing happens with the RTG Boiling Point Jackpots.

The online slot game in which this feature has been introduced is Spirit of the Inca. The player can play up to five independent jackpots. If he plays with maximum bet then he will be eligible for all five jackpots. At lower bets only some of the jackpots will be enabled in proportion to the bet. The five jackpots are displayed above the reels and in order of increasing amount are Mini, Minor, Major, Maxi and Grand. Below each jackpot are given two figures. The one in bold is the present value of the jackpots, which are akin to the present temperatures. These keep increasing with each wager just like the current value of progressive jackpot online slots. The bottom numbers are the boiling points. A jackpot is hit when its current value reaches the boiling point. The player whose spin takes the jackpot to its boiling point will win the amount given in the boiling point for that jackpot. Players can win more than one jackpot per spin if they reach the boiling points of more than one jackpot in that spin.

The Boiling Point Jackpots are not the only feature in the RTG Spirit of the Inca online slot game. The Incan Spirit is the wild symbol and it also offers the highest line payout of 2,000 coins. It expands to cover the entire reel before payouts are awarded. The Incan Spirit can appear on more than one reel at the same time. The priestess is the scatter symbol. The other symbols are mostly artifacts from the Inca culture. There is another innovative feature introduced by RTG in the Spirit of the Inca slot game. The feature is triggered when the Incan Spirit appears at the same time on reels 1 and 5. 15 bonus symbols are displayed on the screen and the player is asked to pick 5 of them. The first three picks will award up to 25 free spins each. The fourth pick will award a multiplier ranging from 1 to 10. The fifth pick is very interesting. It may award a wild reel or an extra wild symbol on each reel during the free spins or it may award nothing at all. Spirit of the Inca can be played at all RTG online casinos like Club World, Slots Jungle and Win Palace.
