Xtreme Summer Hot is a 5x3, 20-payline video slot including re-spins, a gamble feature, and expanding sticky wilds.
The 7 is the wild symbol, while the star serves as the scatter. Wilds can land on any of the three middle reels, and expand to cover the entire three middle reels, then remain sticky for up to three re-spins. The reels without expanding wilds will re-spin and present a chance to land more expanding sticky wilds on the second, third and fourth reels, which will give an additional re-spin. The feature ends when no more wilds appear during the re-spin. Three to five scatters will award wins according to the pay table.
This slot includes a buy feature that players can use to buy expanding wilds, and a double-or-nothing gamble feature by which winnings can be gambled up to 5x.
