Extreme Heat 7s OverviewExtreme Heat 7s is a fiery classic fruit slot from Foxi (Fazi), released on 3 September 2026. It plays on 5 reels and 4 rows with 40 fixed paylines, and bets range from 0.08 to 180 per spin. The look is pure old-school – lucky 7s, BARs and fruit – but the feature list is much longer than in a typical fruit machine. The RTP is 96.46%, the volatility is medium and the maximum win is 1,616x the bet. The game offers a Wild on the middle reels, a paying Star Scatter, a Respin Feature triggered by just two Scatters, up to 30 Free Spins that can be retriggered, a Buy Bonus menu with three options and a red-or-black Gamble. Theme and GraphicsAs the name suggests, everything in Extreme Heat 7s is on fire. The reels sit in a gold frame on a dark red background, surrounded by orange flames that flicker across the whole screen. The golden "Extreme Heat 7s" logo with a red 7 shines in the top left corner. The symbols are drawn in a clean, glossy style: shiny red 7s, golden BAR tiles, watermelons, grapes, bananas, apples, oranges and cherries. Winning symbols and the Wilds burst into flames when they land, which gives the classic layout a modern, energetic feel. PaytableWins pay left to right on adjacent reels, starting from the leftmost reel, and wins on several lines are added together. With the maximum bet of 180, the paytable shows:
The red 7 is the only symbol that pays for just two in a row, and the five-Scatter prize is the biggest single payout on the paytable. The Wild SymbolThe Wild is a golden "WILD" text that catches fire when it lands. It appears only on reels 2, 3 and 4 and substitutes for all symbols except the Scatter. Because it lands on the middle reels, it is the key to connecting lines between the first and last reels. In the free spins, several Wilds can land together and complete many of the 40 lines at the same time. Star Scatter and the Respin FeatureThe Scatter is a golden star with the word "SCATTER" on it. It pays anywhere on the screen, and it also triggers two features. The first one is the Respin Feature, which starts with only 2, 3 or 4 Scatters:
The feature continues until no new Scatter appears or all five reels hold a Scatter. Line wins are paid before the respins begin, while the Scatter wins are paid at the end – so the respins can turn two Scatters into a much bigger Scatter prize, or even into the free spins. The Respin Feature can also be triggered during the free spins. Free Spins FeatureThree, four or five Scatters award 10, 20 or 30 Free Spins. During the feature, every new Scatter combination awards extra free spins in the same way – 10 for three, 20 for four and 30 for five – and they are added to the remaining total. All free spins are played with the same bet and lines as the triggering spin. In our demo session, a spin with five Scatters spread across the reels awarded the full 30 Free Spins. The round was full of Wilds: one spin with three Wilds and stacked BARs paid 4,657.50, another one with five Wilds and a column of apples paid 3,960, and the free spins total climbed above 12,000 on a 180 bet. Buy BonusThe Buy Bonus button next to the reels opens a menu with three options. The price is your total bet multiplied by a fixed coefficient:
At a 180 bet, that means 7,200, 14,400 or 27,000. After pressing Buy, a confirmation screen appears, and the feature starts once you confirm. The average RTP of the Buy Bonus is 96.44%, almost the same as in the base game. Bonus buys are not available in every casino or jurisdiction. Gamble FeatureAfter a win, you can press the x2 button to enter the Gamble. A card is drawn, and you choose red or black: a correct guess doubles the amount, a wrong one loses it. The previous cards are shown in a row at the top, and the Collect button moves the current win to your balance at any time. The gamble win limit is 100,000. Game ControlsThe balance is shown at the bottom left and the bet at the bottom right, where you set it with the plus and minus buttons. On the right side of the reels you will find the Buy Bonus button, autoplay, the large green spin button and the turbo switch. The menu and the "i" button at the bottom left open the settings, the rules and the paytable. RTP and VolatilityAn RTP of 96.46% is slightly above the industry average, and the medium volatility fits the game well. The base game pays regularly thanks to the many lines and the Respin Feature, while the bigger wins come from the free spins and the Scatter pays. The 1,616x maximum win is reached mainly in the bonus round. Who Should Play ItExtreme Heat 7s is for players who like the classic 7s-and-fruit style but want more action than in a simple fruit machine. The respins, the retriggering free spins and the Buy Bonus add plenty of variety. Try the free demo first to see how often the Scatters show up.
