Stacked Fire 7s

Stacked Fire 7s is a classic retro-style slot that captures the essence of traditional Las Vegas casino gaming. The game features a fiery theme, with the reels set against a blazing background dominated by red and orange hues. This creates an atmosphere of excitement and intensity, reminiscent of the thrilling experience found on casino floors.

Stacked Fire 7s appears to be part of a “Fire 7's” series by Inspired Gaming. It shares similarities with Super Fire 7's, released in 2018, including identical symbols, reels, and logo design. This suggests that Inspired Gaming has created a series of slots centered around the “Fire 7's” theme, offering players variations on a familiar and popular concept.

Core Game Mechanics

Stacked Fire 7s is played on a 5×4 reel grid with 40 fixed paylines. The game uses a left-to-right payout system, requiring a minimum of three matching symbols on consecutive reels, starting from the leftmost reel, to form a winning combination.

The slot features eight regular paying symbols, including three types of 7s (Fiery, Red, and Blue) as high-value symbols, and classic fruit machine icons like Golden Bells, Watermelons, Oranges, Grapes, and Plums as lower-value symbols. All symbols appear stacked on the reels, increasing the potential for multiple wins on a single spin.

A Wild symbol is present in the game, appearing stacked on reels 2, 3, and 4. It substitutes for all regular paying symbols to help create winning combinations. The game also includes a Scatter symbol, which appears on reels 1, 3, and 5 in the base game and is key to triggering the bonus features.

The betting range starts at 0.20 coins and can go up to 100 coins per spin, depending on the casino's set limits. This wide range caters to both casual players and high rollers.

Bonus Features

1. Free Spins Bonus: The Free Spins feature is triggered when three Scatter symbols land on reels 1, 3, and 5 simultaneously in the base game. Upon activation, players are awarded 8 free spins. During this bonus round, only the Wild symbol and the high-paying 7s symbols appear on the reels. This significantly increases the potential for high-value wins, as all low-paying fruit symbols are removed. The stacked Wild symbols continue to appear on reels 2, 3, and 4 during free spins, further enhancing win potential.
2. Gamble Feature: After any win of 5x the bet or higher, players have the option to enter the Gamble Feature. This bonus presents two wheels, the left (where players can double or triple the current win) and the right (where players get an opportunity to win free spins). Players can adjust the values on the wheels, which affects the odds of a successful gamble. The maximum number of free spins that can be won through this feature is 30. It's worth noting that this feature can be toggled on or off according to player preference and may not be available in all jurisdictions.
3. Stacked Symbols: While not a separate bonus feature, the stacked nature of all symbols in both the base game and free spins is a key element of the game's mechanics. This stacking can lead to multiple payline wins on a single spin, particularly when combined with the stacked Wild symbols on the middle three reels.

Interesting Feature

A standout aspect of Stacked Fire 7s is its Free Spins bonus round. By removing all low-paying symbols during this feature, the game creates a high-volatility environment where only premium wins are possible. This design choice significantly ramps up the excitement and win potential, offering players the chance for substantial payouts during the bonus round. The combination of this feature with the stacked symbols and Wilds creates a uniquely thrilling gaming experience that sets Stacked Fire 7s apart from many other retro-styled slots.
