HEAT Double

HEAT Double Overview

HEAT Double is a compact fruit slot from the Redstone studio, released on 5 June 2023 and listed on our site under Foxi (Fazi), like the other Redstone games. It runs on a 3x3 grid with 5 paylines. SlotCatalog lists a 96.33% RTP and stakes from 0.50 to 50; it does not publish a volatility rating or a maximum win.

The Paytable

We played at a stake of 10.00, which means 2.00 per line. For three of a kind the game’s symbol page shows:

• red 7s: 1,500 (150x the stake);
• golden bells: 500 (50x);
• BAR: 150 (15x);
• plums, watermelons, lemons and cherries: 70 each (7x);
• the X symbol: 10 (1x).

Three Jackpots

Above the reels sit three jackpot meters marked with a diamond, a gold bar and a silver bar. In our session they stood at 5,880.40, 980.50 and 138.10. SlotCatalog lists the jackpot as progressive, which fits the odd, growing amounts. The game rules add two details: after every jackpot win the pot restarts from a base value greater than zero, and each jackpot has its own minimum bet – a casino can also switch individual jackpots off, in which case they are marked on the meter.

The x2 Fruits

The row of icons above the jackpots shows watermelons, plums, lemons and cherries, each marked x2. The game’s own rules explain the rule behind them: “Fill all reels with the same fruit symbol and get a 2x multiplier.” A screen of nine cherries or nine plums therefore pays double. Our screenshots show the fruit lines bursting into flames when they pay, which is where the HEAT in the name comes from.

How the Lines Pay

The rules state that all pays are left to right, beginning with the leftmost reel, except scatter symbols, and that the scatter pays on any position. With only three reels, a win always needs the full row: there are no two-symbol pays, even for the 7s. Five fixed lines run across the three rows and the two diagonals, and the line numbers are marked on both sides of the reel frame.

Our Wins

• 140.00 (14x) – two lines of cherries, 70.00 each.
• 210.00 (21x) – a Big Win: three lines of plums across the grid, 70.00 each.

Reading the Numbers

With only one way to hit each line, the paytable is easy to read against the stake. Three 7s on a single line return 150x, and a full screen of one fruit covers all five lines at 7x each before the x2 is applied. The four fruit symbols all pay the same 70, so the x2 panel is what separates a good fruit hit from an ordinary one. The jackpots sit on top of this: the diamond pot was worth almost 590x our 10.00 stake when we played.

Who It Is For

HEAT Double is for players who want an old-school three-reel fruit machine with only five lines to follow and three jackpots ticking above it.
