Booming Seven Deluxe: Design and Theme
🖼️ Graphics
Everything here is deliberately showroom-casino style: behind the reels you can see a slot hall with machines, a counter, and soft lighting, while the screen itself feels framed with bulbs. The main stage is filled with glossy fruits and sevens, and the interface changes colour depending on the situation: the base game is dominated by a purple panel, help screens use bright cards, and during the gamble round, the screen suddenly turns red, as if the machine is saying, “So, shall we test your nerves?”
🎶 Sound
The audio is a typical retro-slot package: short jingles on matches, a light casino-floor ambience underneath, and a simple melody looping in the background. That repetition can become genuinely tiring — during longer sessions, you may want to either turn the music down or leave only the win sounds on, just to avoid the feeling of the same record playing over and over again.

Special Symbols
To understand how to play Booming Seven Deluxe, it is enough to grasp the logic of the base paylines and a few symbols that periodically change how wins are calculated and affect the game pace.
- Wild (gold bars): substitutes for any symbols except the scatter. It also pays on its own — 3 wilds award x7.7 of the stake. In addition, it is required to trigger the 2-Way Pay mode.
- x7 Multiplier (diamond 7): appears only on the second reel, substitutes for any symbols except the scatter, and if it forms part of a winning line, it multiplies the payout by x7.
- Scatter (red 777): does not substitute other symbols, is used to trigger free spins, and also pays on its own — 3 scatters award x7 of the stake.
Bonus Game
Booming Seven Deluxe features several modes — free spins, 2-Way Pay, and the gamble game — each triggered under its own conditions.
- Free Spins: three scatters anywhere on the screen award 10 spins. If 3 scatters land again during the bonus, another 10 spins are added.
- 2-Way Pay: three or more wilds on the screen activate 2-Way Pay for 10 spins. During this mode, paylines are paid in both directions — left to right and right to left. If 3 or more wilds land again during 2-Way Pay, another 10 spins are added. If 3 scatters appear during 2-Way Pay, free spins are triggered, while the remaining 2-Way Pay spins are put on hold and resume afterwards.
- Gamble Game: after a win, you can choose one of two options to try to double the amount. The streak can continue for up to 10 successful attempts in a row. There are restrictions: wins obtained during free spins cannot be gambled.
RTP, Volatility, Max Win
RTP — 96.55%. Volatility is low to medium. The provider has not specified the maximum win.
Our Verdict
In Booming Seven Deluxe, the base game runs smoothly and calmly, while most of the excitement begins when bidirectional payouts are activated or when the rare x7 multiplier lands on the second reel. The gamble game adds pace, but it works more as a nerve-testing accelerator than a mandatory feature.
In terms of dynamics, the slot is better suited to short sessions and simple rules rather than long hunts for complex feature chains — and yes, the looped melody can start to feel oppressive over time, so sound settings genuinely help here.
If you want straightforward gameplay with an unusual win-direction mechanic, Jackpot 3x3 is worth a look. For a more modern option, Wild West Gold offers free spins with a guaranteed x10 if the bonus underdelivers.
