Booming Seven Deluxe Review
I’ve played Booming Seven Deluxe for years. It’s a super charged classic with a 3x3 layout and 10 paylines that can pay both ways. The game builds on the original with diamond encrusted x7 multipliers and a clean fruit machine set. Hits land often enough to keep the balance moving, yet the slot still throws punchy bursts when features line up. The focus is simple spins, clear payouts, and fast rounds, which suits short sessions and longer grinds when features chain.

Booming Seven Deluxe Attributes
I rate the maths model as friendly. RTP sits at 96.55% and variance is Low-Med, backed by a hit frequency around 41 percent. The max win is x2422, which is fair for a 3-reel machine. Bets stretch from 0.01 to 500, so I can test lines or ramp up. Layout is 3-3 with 10 lines. With three Wild symbols anywhere, the 2-Way Pay can activate, turning lines into Bothway and paying from left to right and right to left.
Feature set stays classic. Bothway, Free Spins, a Multiplier, a Risk or Gamble double game, Scatter symbols, and Wilds. Themes stick to Bell, Cherry, Diamond, Fruit, Gold bars, Lemon, Orange, Pineapple, and a violet backdrop with sparks. It’s HTML5, light on load, and snappy. Release date was 15 December 2016 and the latest update refreshed assets. I keep returning because the feature mix works on a compact grid without clutter or gimmicks that slow the cycle.
Special Symbols in Booming Seven Deluxe
In Booming Seven Deluxe, the red lucky number 7s act as the Scatter. Two icons serve as Wilds, the golden bar and the diamond x7 multiplier. Both can complete a winning combination by substituting for any icon except the red lucky number 7s. The diamond x7 multiplier Wild only appears on reel 3, and when it lands in the right spot it spikes line wins. I watch that centre reel because it changes the tone of a round. Those subs keep lines tidy when small gaps appear.
The golden bar Wild can by itself trigger the 2 ways pay feature for up to 10 spins when three land on an active payline. That flip makes every line pay from both directions, which stacks nicely with the x7 diamond when it drops on reel 3. Substitutions exclude Scatters, so the red 7s still drive the free spins. I like setups where bars stack on reels one and two, then the centre diamond arrives to tidy the line.

Bonus Rounds in Booming Seven Deluxe
The free spins bonus round awards 10 free spins when I land three red lucky number 7s on an active payline. It can retrigger for 10 more whenever another set of three or more red 7s hit. During free spins, it’s also possible to trigger the 2 ways pay feature, so combinations pay both from right to left and from left to right. That overlap is where most of my streaky wins appear, especially with multipliers in view.
The gamble feature lets me try doubling the previous prize after any win. Pick the same card suits or the colour to double the amount; pick wrong and the win is lost. It’s quick and direct, so I use it only on tidy small hits to pace variance. There aren’t any jackpots in Booming Seven Deluxe, which suits a compact 3x3 as the value is instead spread across retriggers, Bothway windows, and those x7 spikes on reel 3.
Tips to Win in Booming Seven Deluxe
In Booming Seven Deluxe casino slot online, there are no fixed payouts because returns depend on the bet amount and the number of paylines in play. All symbols carry multipliers that apply to the current line bet when three or more of the same kind match. I keep all 10 lines active when hunting features, then nudge stake size, as the multipliers scale cleanly. Bars and red 7s set the tone, while bells and fruits fill gaps and steady the flow.
Top Winning Combinations (Base Game) in Booming Seven Deluxe
Three or more golden bars Wild symbols award the game’s highest prize in the base game. Three golden bars carry a 77x multiplier applied to the current line bet, which is chunky on a full-line hit. Because bars also substitute, I often see them setting up Bothway stretches when stacked. The sweet spot is lining bars across an active payline with the diamond x7 sitting on reel 3 to lift any connected line, though that timing needs patience.
Three or more red lucky number 7s award the second highest prize, a 7x multiplier on the line bet, while still acting as Scatters to trigger free spins when they land as a set. That dual role keeps them busy across sessions. I like to keep stake steady until the first batch drops, as retriggers are frequent enough to plan around, and 7x top-ups during base spins help pad the balance between feature entries.
Golden bells and all fruit symbols, including pineapples, cherries, lemons, and oranges, deliver the lower tier payouts. Multipliers range from 3x up to 20x, applied to the line bet. On a 10-line 3x3, these fills keep spin-to-spin flow alive and are the bridge to better rounds. I see most sessions shaped by steady bell and fruit returns, Bothway windows lifting the totals, then a push when either bars or red 7s string together.
Top Winning Combinations (Bonus Rounds) in Booming Seven Deluxe
During bonus rounds, base game symbols keep the same payout values, so the prize ladder does not shift. The difference is that free spins can overlap with the 2 ways pay feature, which means more lines count and more routes to the same multipliers. I treat the round as a volume play where the board pays both directions and the diamond x7 on reel 3 becomes a focus. Retriggers are the lever that stretches that window for longer.
