To open the GamBonus review of the best slots on BitStarz, we thought we would start with one of the all-time classic slots – Big Bass Bonanza by Reel Kingdom. Although many people associate Big Bass Bonanza with Pragmatic Play, make no mistake, it was Reel Kingdom that created it, but it is available. It’s purely down to the fact that Reel Kingdom has an exclusive partnership with Pragmatic, who has the sole rights to distribute their games.

Originally launched in 2020, Big Bass Bonanza has since spawned 15 titles in the Big Bass series. It’s a measure of the original’s huge success story. The team at Reel Kingdom hooked onto the idea of the peacefulness of fishing being shattered by the excitement of a fisherman hauling in his catch, and they decided to incorporate it as the theme for a slot mach
ine, and boy, what a great idea it proved. It’s not only still one of the best slots on BitStarz, it remains popular with many other online casinos, too.
Game Design
It’s not easy to explain why Big Bass Bonanza became as popular as it did. It just seemed to grab the attention of online slot payers at the time and strike a chord with them. The design of the game had a lot to do with it.
The central character is the bearded Fisherman, and players seem to have taken a shine to him. He’s well drawn, and his infectious smile draws you in. All of the other symbols are simply but beautifully drawn. They and their values are shown in the paytable below.
The Paytable
The card symbols 10, J, Q, K, and A are the low payers, and the highest payer is the Bobbing Float. The fact that there aren’t too many symbols and that their win values are the same in many instances also helps with the simplicity of understanding the gameplay. It’s what makes Big Bass Bonanza one of the best games to play on BitStarz, especially for newbies to online slots.
The Bearded Fisherman Wild
The Wild is the Bearded Fisherman, or Angler, to use the correct term. He smiles amicably as he shows off his catch.
As is usual with most online slots these days, the Wild take the place of all other symbols except the Scatter. The Bearded Angler also plays a significant role in the Free Spins feature. In fact, he only appears during the FS feature. But more of that a little later.
The Big Bass Scatter
The game’s Scatter is the Big Bass, which, as you can see, has been hooked and is fighting to try and avoid being reeled in by our Bearded Angler friend.
You must land Scatters to initiate the Free Spins feature, which is where the fun starts. One of the things that contributes to BBB being one of the best slots on BitStarz 2025 is the progressive nature of its features. The more Scatters you can land anywhere on the grid, the more Free Spins you will be awarded. It goes like this:
- Land 3 Scatters and you’re awarded 10 Free Spins.
- Land 4 Scatters and you’re awarded 15 Free Spins.
- Land 5 Scatters and you’re awarded 20 Free Spins.
The Free Spins Feature
The Free Spins feature is the other reason why Big Bass Bonanza is still one of the best games on BitStarz 2025, several years after its launch. Yes, many slots have free spins rounds, but Big Bass was one of the first games to have a progressive Free Slots Feature.
Each time you land the cheerful Fisherman, he will collect any money showing on visible Fish Cash symbols that have landed anywhere on the grid. If you’re lucky enough to land more than one Fisherman, each one you’ve landed will hook and accumulate the money. The more Anglers you land, the more money you potentially collect. But that’s not all.
When a Bearded Fisherman symbol lands in this feature round, it will register on the progression meter (shown above) that sits at the top of the grid. For every 4 that is collected, you’re awarded 10 more Free Spins. But it gets even better. Progressive multipliers also come into play:
- 1st 4 Fisherman symbols – x2 multiplier activated
- 2nd 4 Fisherman symbols – x3 multiplier activated
- 3rd 4 Fisherman symbols – x10 multiplier activated
As you can see, we are talking some serious multipliers here. As one of the best slots on BitStarz Casino, the maximum you can win is 2,100x your stake, and with a max stake of $250 per spin, that would equate to $525,000.
GamBonus’s Concluding Thoughts on Big Bass Bonanza by Reel Kingdom/Pragmatic Play
No one is absolutely sure why the Big Bass Bonanza slot has become as successful as it has. It’s a standard 5×5, 10 fixed payline slot, with a medium volatility rating and 96.71% RTP. However, its beautiful design, simplicity of gameplay, and progressive features have resonated with players big time. Not only is it still one of the best slots on BitStarz, but it also remains hugely popular with online casinos and players all over the planet.
Maya Lock by 3 Oaks

Maya Lock is a cheeky little slot from software providers, 3 Oaks, and we here at GamBonus believe that, in our expert opinion, it is one of the best slots on BitStarz Casino. It’s fun gameplay, with its mischievous Mayan King who, when he lands on the 5×3 grid, flicks gold coins into 1 of the 2 fat little Piggies that sit on either side of his throne, will keep you amused while you search for Mayan gold. Let’s start our review of the game by taking a look at its paytable.
The Paytable
| Symbol | 3 of a Kind | 4 of a Kind | 5 of a Kind |
| 9 or10 | 0.05 | 0.15 | 0.30 |
| J or Q | 0.10 | 0.15 | 0.30 |
| K | 0.10 | 0.20 | 0.50 |
| A | 0.10 | 0.25 | 0.50 |
| Sapphire Collar | 0.75 | 1.50 | 4.00 |
| Emerald Goblet | 0.75 | 2.00 | 5.00 |
| Ruby Headdress | 1.50 | 4.00 | 8.00 |
| Gold Crown | 3.00 | 6.00 | 20.00 |
Special Feature Symbols
There are several special symbols in the Maya Lock slot by 3 Oaks.
The Wild
The Wild is the Mayan King. In the base game, he only appears on the 2nd row of reel 3, and he will flick a gold coin into 1 of the 2 Piggies, or sometimes into both. He substitutes for all other symbols of the game except the Bonus Symbols.
Bonus Symbols
The Bonus symbols exist on reels 1, 2, 4, and 5. They can also appear on reel 3, but not on row 2. However, they only pay their value during the Free Spins Feature. If you land any Bonus Symbols on any spin together with the Wild, it triggers the Collect Feature, whereby the total shown on any Bonus Coins or Jackpot symbols will be collected.
How to Play the Maya Lock Slot by 3 Oaks
Before you begin spinning the reels, you need to select the amount you want to bet per spin. You’ll see a symbol representing a stack of coins. Click in the bottom RH corner of the screen which, when clicked, will reveal the bet values available. The bet range runs from 0.30 to 90.0 coins. This is a 4o fixed payline slot, so once you’ve set your bet, you can start spinning the reels.
Maya Lock is one of the best games to play on BitStarz because you don’t have to activate the Free Spins round to win big money. You’ll collect money automatically for any wins you land according to the paytable shown above. Furthermore, if you land the Wild and any of the Money Coins or Bonus Symbols, that money too will be automatically collected.
The Free Spins Feature
As already mentioned, Maya Lock has a Free Spins round, as do all of the best slots on BitStarz.
Each time the Mayan King lands, he flips a gold coin into one or both Piggy Collectors. At some stage, one or both Piggy Collectors will, at random, trigger the Free Spins round. This round consists of 6 Free Spins, during which the normal rules of the base game gameplay, apply.
Other Features of the Maya Lock Slot
3 Oaks also included some extra features when they designed this game. It’s another reason that the team here at GamBonus rates this game as one of the best slots on BitStarz 2025.
- The Wild Rewind Feature: This is activated at random during the base game. The edges of the centre cell in the grid will shimmer, and all reels will respin. A wild is guaranteed to land, creating the potential to land one or more winning combos.
- The Bonus Rewind Feature: Unlike the Wild Rewind, the Bonus Rewind can be activated at random during the base game and the Free Spins round. Landing a Bonus Symbol is guaranteed.
GamBonus’s Concluding Thoughts on the Maya Lock Slot Game by 3 Oaks
There is no doubt in our team’s estimation, that Maya Lock is one of the best slots on BitStarz, and we recommend you should try it. It’s a medium volatility slot, so you can expect to land a blend of small to medium money prizes without too much of a wait, but the bigger money wins will come eventually if you persevere. It’s already one of the best games to play on BitStarz, and given that it was only released in July 2025, we don’t think it will be very long before it becomes a world favourite. The RTP is 96.01%.
Pirots 4 by Elk Studios

If you are a fan of fun, Sci-Fi slots with cool characters and amazing animated graphics, you’re going to love Pirots 4 by Elk Studios. We’ve chosen it as one of the best slots on BitStarz Casino for all of the reasons just described, plus the fact that it also offers some terrific features for you to try out, and the fact that you can win up to €20,000.
For the uninitiated, Pirots is the name given to parrots that once belonged to the captains of pirate ships. No longer content to sit on their masters’ shoulders, they revolted, outsmarting and outwitting their former masters. The Fearful Four became the scourge of the 7 seas, and the Pirots slot became one of the best games to play on BitStarz Casino. That was back in 2023, when Elk Studios launched the original Pirots slot with its new CollectR™ mechanic. 2 years and 4 slots later, with the launch of Pirots 4, our feathered felons take to outer space as space bandits.
We begin our exploration of this extraordinary new slot with its paytable.
The Pirots 4 Paytable
In addition to the Gem Symbols shown above, Pirots 4 also has a host of Special Feature symbols, which we discuss individually below the gameplay section.
How to Play Pirots 4 by Elk Studios
During the base game of what is one of the best slots on BitStarz 2025, the 4 Pirots move around the 7×7 grid collecting Gem Stones (which can be upgraded to payout level 7) that match the colour of their plumage. They also collect any available Feature Symbols that are available. The Gems can have their levels upgraded by Upgrade Symbols, raising their values by 1, 2, or 3 levels. Once all of the symbols have been collected, new Pirots and symbols cascade down, and so long as one of the Pirots is active, the ‘spin’ continues.
Each time a Gem or Wild symbol is collected, it adds to the Collector Meter above the grid. If the Pirot stops, so, too, does the Meter, and it then resets. Pirots 4 is definitely one of the best slots on BitStarz, as it’s full of action. If 2 adjacent Pirots can’t collect more symbols, they can pull off a ‘Swtcheroo.’ If 3 or more adjacent Pirots can’t collect any more symbols, it triggers a ‘Power Clash,’ clearing gems in a 5×5 area surrounding the Pirots. The birds then flee the scene, collecting any Corner bombs, Alien Invasion, Black Holes, coins, or Scatter/Super Scatters symbols that lie in their path.
Special Feature Symbols
The Black Hole symbol sucks in all Pirots and symbols and redistributes them into random positions. It has the power to remove and reposition up to 3 Pirots.
The Wild symbols can substitute for any Gem symbols of the same colour and will do so at the same level of payout value.
The Coin Symbol. There are 5 different Coin Symbols. Their value are: 5x, 10x, 100x, 500x, and 1000x. The symbols increase the payout by multiplying the stake by the coin’s face value.
The Many Features of Pirots 4
The best games on BitStarz 2025 are crammed full of exciting features, none more so than Pirots 4. They include:
- Alien Invasion: This is activated when a Pirot collects an Alien Invasion symbol, and it can’t collect any more symbols. It triggers a battle between a Space Bandit and a Pirot.
- Lost in Space: The Lost in Space feature plays on an expanded 8×8 grid, beginning with 3 Free Spins.
- Charlie’s Xtra Chance: When no more symbols can be collected, this feature is triggered at random. It exploded one of the Corner Bombs, causing new symbols to cascade down.
- Free Spins: Activated when you land 3 or more Scatters. You are awarded 5 Free Spins. If one of the Scatters is a Super Scatter, the round plays out on an 8×8 grid.
- X-citer: When this feature activates, it enables you to win some extra cash and access some shortcuts, including an ante-bet.
GamBonus’s Concluding Thoughts on the Pirots 4 Slots by Elk Studios
With so many great, original features, it comes as no surprise that the team here at GamBonus has rated Pirots 4 as one of the best slots on BitStarz. It’s so feature-rich that newbies might find it something of a challenge to get to grips with them all, but once you do, it’s certainly one of the most entertaining slots you’ll come across anywhere. Pirot 4’s RTP is 94% and it has a medium volatility rating.
You can play all 5 of the Pirots slot series on BitStarz Casino either for real money (minimum bet size $0.20) or in free, demo mode, so any one of them can qualify as being the cheapest slot on BitStarz.
