Yet another addition to the overflowing chest of pirate-themed slot games! Our Cannonball Riches slot review will cover this Playtech entry that tries to keep things interesting. Not dead in the water, after all! With a 6x5 layout, Scatter Pays system, and cascading wins, this game tries to ride the same stormy wave as titles like Gonzo’s Quest and Sweet Bonanza, but with cannonballs and multiplier bombs instead of ancient idols or candy. The setting is classic pirate cartoon fare: two galleons stare each other down across the reels, and every spin feels like a shot across the bow. Playtech Origins has packed in popular mechanics—sticky multipliers in free spins, random multiplier bombs, and a fairly priced feature buy. It plays fast, looks sharp, and offers enough explosions to keep casual players entertained. But is it enough to stand out in a genre already jammed with treasure maps and parrots?
Cannonball Riches drops anchor with a 6-reel, 5-row setup and uses the Scatter Pays system—meaning paylines do not matter. Instead, wins are formed by landing 8 or more matching symbols anywhere on the grid. It is clean, uncluttered, and ideal for cascading gameplay.
Bets start at £0.10 and go up to £100 per spin, giving it broad appeal. There is also an Extra Bet option that adds 20% to your stake in exchange for better odds of triggering the bonus feature—though Playtech keeps the exact boost percentage vague.
For those who prefer skipping the build-up, the Buy Feature is priced at 75x your stake and awards 4 to 6 scatters randomly.
The default RTP sits at a decent 96%, but operators may use lower versions too, so always check before spinning. This is a high-volatility slot with a hit frequency of 25.11%, which is fairly active for a slot game in this category. The top prize is 5,000x your base bet, with wins over 1,000x expected roughly once in every 230,965 spins. Solid potential, if you can weather the waves.

Cannonball Riches does not rewrite the rulebook, but it nails the presentation. You get a bright, cartoonish pirate world, complete with rival ships flanking the reels and cannons ready to fire multipliers at random. The sea is stormy, the soundtrack leans heavily on the “yo-ho-ho” vibe, and everything moves with the pace of a barrel rolling downhill.
It is a Scatter Pays slot, so symbols do not need to line up. Just hit 8 or more of the same icon anywhere on the grid to score a win. There are no Wilds here; everything is handled through symbol combinations and special bombs.
High-paying symbols include anchors, compasses, pirate coins, and spyglasses. Mid- to low-tier symbols feature treasure maps, hearts, diamonds, clubs, and spades. The highest-paying symbol is the Anchor, which pays up to 5x your stake for 12 or more. Mystery Bombs and Multiplier Bombs can land during spins and add random or fixed multipliers to your total win, but they are not symbols in the traditional sense.
Spades
8 = 0.4x stake / 10 = 0.2x stake / 12 = 0.1x stake
Clubs
8 = 0.5x stake / 10 = 0.4x stake / 12 = 0.2x stake
Diamonds
8 = 0.7x stake / 10 = 0.4x stake / 12 = 0.2x stake
Hearts
8 = 0.8x stake / 10 = 0.5x stake / 12 = 0.3x stake
Treasure Map
8 = 1x stake / 10 = 0.6x stake / 12 = 0.4x stake
Spyglass
8 = 1x stake / 10 = 0.6x stake / 12 = 0.4x stake
Pirate Coin
8 = 2.5x stake / 10 = 1x stake / 12 = 0.5x stake
Compass
8 = 2.5x stake / 10 = 1x stake / 12 = 0.5x stake
Anchor
8 = 5x stake / 10 = 2x stake / 12 = 1x stake
Cannonball Riches is built using HTML5, and it shows. Everything is crisp, clean, and responsive on mobile devices. The 6x5 grid fits comfortably on both portrait and landscape screens, with well-sized icons and intuitive controls that never feel cramped.
Whether you are adjusting your stake, toggling the Extra Bet, or activating the Buy Feature, every interaction is smooth and lag-free. The animations—like ships firing multiplier bombs or wins cascading down—play out flawlessly, even on smaller screens.
Playtech has clearly optimised this slot for mobile-first gameplay, and it holds up perfectly on any device.
Cannonball Riches may look playful on the surface, but beneath the cartoon visuals is a volatile, feature-rich slot packed with tumbling wins, multiplier bombs, and sticky free spin modifiers. Most of the action revolves around increasing multipliers and cascade sequences.
The base game has plenty of spice, but it is the Free Games feature that gives the best shot at big wins.
Triggering the bonus is simple: land 4, 5, or 6 FREE GAMES symbols anywhere on the reels to receive 10, 12, or 14 free spins, respectively. During the bonus round, the multiplier bar does not reset between spins. This is the big change.
Each win adds +1 to the multiplier, and it keeps growing as long as you keep landing hits. This makes late-stage free spins far more potent, especially with extra Bomb symbols boosting the count or dropping in extra multipliers.
You can also retrigger with more bonus symbols.
Like other Scatter Pays slots, Cannonball Riches uses a cascade mechanic. Whenever 8 or more of the same symbol land and pay out, they explode and make room for new symbols to drop from above. If new combinations are formed, the process continues.
Every cascade also increases your multiplier by +1, which is applied to the total win once the sequence ends.
At the top of the screen is a multiplier bar that starts at 0 and increases by +1 with every win in a cascade sequence. The final multiplier is applied at the end of the round to the total win. In Free Games mode, this multiplier does not reset between spins, allowing it to build over time.
Multiplier Bombs can land anywhere on the reels. When one lands and there is a win, the bomb’s multiplier value is added to the multiplier bar. These can drop during both the base game and Free Games. This, in turn, offers a sharp boost to potential payouts.
The Mystery Bomb is a wildcard. It behaves just like the regular bomb, but its multiplier is random (anywhere up to 500x). If it lands and a win occurs, it gets added to the multiplier bar.
Frankly speaking, yes, it is rare, but when it hits, it can change the tone of the session completely.
The ships on either side of the reels are not just background art! They occasionally fire a multiplier bomb directly onto the reels. This can happen at random and helps break up long dry spells with sudden surges in potential payout. And to be honest with you, it kind of gave me a jump scare the first time it happened all of a sudden.
Well, all the more reason to check out a detailed slot game review before playing it.
The Extra Bet option boosts your chance of triggering the Free Games feature. It costs 20% more per spin but could save you from waiting through hundreds of regular spins. Playtech does not say exactly how much it improves your odds, but the difference is noticeable over time.
For 75x your bet, you can buy straight into the Free Games bonus. You will randomly receive 4 to 6 FREE GAMES symbols, giving you between 10 and 14 spins. It is a good mid-tier price point—neither cheap nor outrageous—and gives players a way to skip straight to the action.
Cannonball Riches is one of those slots that feels light-hearted but hides some serious volatility under the surface. I liked the pirate aesthetic. It is cheerful without being corny. And the fact that Playtech added some nice touches like ship animations and multiplier bombs made it feel a bit more alive than your average Scatter Pays game.
Still, I found myself comparing it to Sweet Bonanza or Pirate Kingdom Megaways more than once. The bonus round can snowball beautifully with a growing multiplier, but the base game can drag if you hit a dead patch.
I did enjoy the pacing once things started clicking, especially when mystery bombs fired off or a lucky retrigger extended the free spins round. It is not groundbreaking, but it is polished, accessible, and delivers a decent mix of excitement and frustration—which is exactly what a good high-volatility slot should do.
Cannonball Riches gets the job done. It is a modern pirate-themed slot with plenty of action, a fair bonus buy, and a rewarding bonus mode. It will not do anything new as far as scatter slots are concerned, but it is fun, balanced, and full of clever little moments that keep you engaged.
