What Is Deep Blue Jackbomb?
Deep Blue Jackbomb is Felix Gaming’s take on the underwater slot, and it commits fully to its theme. The 4×4 grid sits inside what looks like a deep-sea observation window, surrounded by bioluminescent creatures, coral, and drifting debris. Every UI element has been designed to feel submerged — the paytable is tucked inside a clamshell, buttons resemble bubbles. It’s a cohesive aesthetic for a 2020 release from a studio founded in 2016.
The gameplay is deliberately stripped back. Felix Gaming built this game around two things: a wild multiplier that rewards clustered wilds with exponential payouts, and four progressive jackpots sitting at the top of the screen, ticking upward with every spin across the network. There are no free spins. No bonus rounds. No pick-and-click features. Just base game wins, wild multiplier combinations, and the random chance that a Jackbomb fires.
Deep Blue Jackbomb suits players who prefer uncomplicated mechanics and are drawn to progressive jackpot potential. It is not a game for anyone who needs frequent feature triggers to stay engaged — the base game can be quiet for stretches, and the jackpots are entirely chance-based. If you enjoy watching multipliers stack and you understand the appeal of chasing a random progressive prize, this is worth your time.
Open the paytable via the clamshell icon before you start and note that all values displayed reflect your current bet size.
RTP and Volatility
Deep Blue Jackbomb carries an RTP of 95.78%, which sits slightly below the online slot average of around 96%. Felix Gaming has rated the game’s volatility at 3 out of 5 — medium — which aligns with what players report in practice: wins arrive with moderate frequency, but the big numbers depend on wild multiplier combinations or a jackpot trigger.
One important caveat with progressive jackpot pokies: a portion of every bet feeds the jackpot pools rather than returning to players via standard base game wins. This is standard for the genre, but it means the 95.78% RTP figure encompasses both the jackpot contributions and normal gameplay returns. In practical terms, the base game alone will feel slightly tighter than a comparable non-jackpot pokie at the same RTP.
Think of it this way: over millions of spins across all players, the game returns roughly $95.78 per $100 wagered in total, including jackpot payouts. Your individual session depends heavily on whether the wild multipliers fire well and, less predictably, whether any of the four jackpots drop during your play.
Budget for medium-length sessions rather than short sharp bursts — this game rewards patience over impulsive stake adjustments.
Betting Range
Deep Blue Jackbomb runs from $0.20 to $60.00 per spin. Bets are adjusted via the + and − buttons at the bottom of the screen. The paytable updates automatically to reflect your current stake, so always set your bet before reviewing symbol values.
A higher bet increases your contribution to the jackpot pools and, according to Felix Gaming, raises your chances of a jackpot trigger — though the exact mechanism is not published and the result remains random. You do not need to bet the maximum to be eligible for any of the four jackpots.
Autoplay is available for players who prefer continuous spins without manual input. Set your stake first, then activate Autoplay via the dedicated button at the bottom of the screen.
How to Play Deep Blue Jackbomb — Step by Step
- Set your bet. Use the + and − buttons to choose your total wager per spin. All paytable values update in real time to reflect your chosen amount.
- Open the paytable. Click or tap the clamshell icon at the bottom left. Review symbol values, the wild multiplier scale, and the four jackpot meters displayed above the reels.
- Spin the reels. Hit the spin button. Wins form when matching symbols land on adjacent reels starting from the leftmost reel — this is a ways-to-win setup, not traditional paylines. You need at least two matching symbols on consecutive reels from reel 1 to register a payout.
- Watch the wilds. The gold skull coin wild appears on all four reels. When it lands and contributes to a winning combination, it applies a multiplier to that win. One wild doubles the payout. Two wilds quadruple it. Three wilds multiply it by 8x.
- Monitor the jackpot meters. The four progressive jackpots are displayed above the reels at all times. They can trigger randomly on any spin. Higher bets increase your odds of a trigger, but no specific combination or condition is required.
- Collect your win. After each spin, any winning combinations and multipliers are calculated and credited. There are no additional decisions to make during base game play.
Try this: Set a session budget of $20 at $0.20 per spin. That’s 100 spins to get a feel for how often the wilds land and stack. Raise your stake only once you’ve seen the game’s rhythm.
Symbols
Deep Blue Jackbomb uses nine regular paying symbols split across two tiers, plus the wild.
The three low-paying symbols are marine life: a jellyfish, a starfish, and a seahorse. These fill winning combinations frequently but return modest amounts.
The six high-paying symbols are pirate-themed relics: a message in a bottle, a skull, a sabre, a cannon, and a gold coin. These drive the meaningful base game returns, particularly when a wild multiplier amplifies them.
The wild is a gold coin embossed with a skull pattern. It appears on all four reels, substitutes for every regular symbol, and carries the game’s core multiplier mechanic. A wild that completes a winning combination doesn’t just help — it doubles the payout at minimum, with exponential scaling when multiple wilds land together.
Exact multiplier values per symbol combination are displayed in the in-game paytable. Check them at your specific stake before playing.
Bonus Features
Wild Multipliers
The skull-coin wild is the engine of this game. It appears across all four reels and activates a multiplier whenever it contributes to a winning combination. One wild in a win doubles the payout. Two wilds in the same win quadruple it. Three wilds multiply the win by 8x.
This stacking multiplier is what produces the game’s larger base game wins. A high-value symbol line completed by two or three wilds can return substantially more than the base paytable value suggests. The multipliers apply per winning combination, not per spin — so if multiple wins trigger in the same spin and each involves wilds, each win receives its own multiplier.
There is no condition required to activate the wild — it behaves as a standard wild in terms of substitution and triggers its multiplier automatically whenever it plays a role in a payout.
Four Progressive Jackpots (Jackbomb)
Deep Blue Jackbomb features four progressive jackpots displayed permanently above the reels. All four grow with every spin played across the network. They trigger randomly — there is no specific symbol combination or bonus round required. Any spin, on any bet, can produce a jackpot trigger.
Higher bets increase your probability of triggering a jackpot on a given spin. Felix Gaming has not published the exact odds or contribution rates, which is standard practice for progressive titles. The jackpot values are not fixed and fluctuate based on network activity at the time you play.
The four tiers range from a smaller, more frequently paid prize at the bottom to a larger, rarer top jackpot. Because the jackpots are progressive and network-funded, the top prize in particular can grow significantly before it is won. Once a jackpot is claimed, it resets to a seed value and begins accumulating again.
No published maximum win for the jackpot tiers exists for this game — the 500x stated max win refers to non-jackpot base game payouts only. Treat any jackpot win as a bonus on top of your base game session, not something to budget around.
Is Deep Blue Jackbomb Worth Playing?
Pros:
- The 256 ways-to-win setup on a 4×4 grid produces more frequent hit combinations than a traditional 9-payline layout
- Wild multipliers scale well — three wilds in one win at 8x can produce genuinely strong base game returns
- Four progressive jackpots add an element of session unpredictability; the chance of a random trigger on any spin is a legitimate draw
- Clean, focused design with no feature bloat — easy to understand in under two minutes
- $0.20 minimum bet makes it accessible without forcing large session budgets
Cons:
- No free spins and no standard bonus rounds; base game is the entire experience, which will frustrate players who want triggered features
- 95.78% RTP is below average for a non-jackpot pokie — part of every bet funds the jackpot pool, making the base game feel slightly tighter than the headline figure implies
- Jackpot trigger conditions and odds are not published by the developer, which makes informed bankroll planning difficult
- The game has limited distribution — it’s available in relatively few markets and casino lobbies compared to NetEnt or Pragmatic Play titles of the same era
Deep Blue Jackbomb is a solid, unfussy pokie for players who are comfortable with a feature-light experience and enjoy having progressive jackpots in the background of every session. The wild multiplier system does real work and keeps individual spins interesting. Go in knowing the RTP runs slightly below average and that the jackpots, while genuinely random, are the exception rather than the expectation.
Responsible Gambling
Deep Blue Jackbomb uses a certified random number generator (RNG). Every spin is an independent event — progressive jackpots, wild multipliers, and all base game outcomes are determined randomly and cannot be predicted or influenced. Set a budget before playing and stop when you reach it. If gambling stops being enjoyable, support is available through your local responsible gambling service.
