123 Boom! is a 4thePlayer 1024 fixed betways, High volatility product, which has a RTP of 96.4 % and x14827 as the maximum possible win (released on Nov. 18, 2020). Those are the special features of this slot machine: Free spins, Wild, Scatter, Multiplier, Avalanche reels.
Pirate Wars On The Grid
123 Boom! by 4thePlayer is set on the open sea, highlighting two battling ships that sandwich the 5 reels and 4 rows. Each spin can land a prize from left to right across 1024 paylines. I think the pirate look is easy to spot: maps, flintlock pistols, and grinning skull flags fill the reels, while the soundtrack features creaking wood and cannon blasts. The entire setup has a bit of an old-school flair, which might appeal to players who like a more straightforward design.
As soon as you load it, you’ll see the reel layout is flexible enough for mobile screens. In my opinion, spinning in portrait mode feels natural, but some might prefer rotating their device. The visuals aren’t too cluttered, so even smaller screens can display all symbols pretty well. The two highest paying icons here are a cunning pirate lady and a bearded captain, awarding up to 20x your stake on the right combination. The maximum win can push up to x14,827 your wager if you manage a strong chain reaction. Betting starts as low as 0.10 EUR and stretches up to 50 EUR, so most bankrolls should find a comfortable zone.
Climbing The Crow’s Nest
The overall theme is undoubtedly pirates, and it sets a slightly dramatic but fun atmosphere. Cannons line the battle-ready ships, swirling seas are in the background, and the music tries to hype you up. In my opinion, it’s a decent mix of lively visuals and a playful audio track, though it’s not the flashiest production out there.
I do like that it pays left to right consistently, giving me a traditional approach. The bet mechanics let you toggle between 0.10 EUR and 50 EUR, so casual bettors and bigger risk-takers can find their sweet spot. 123 Boom! dropped back on Nov. 18, 2020, and it’s powered by 4thePlayer, a developer that’s usually transparent about game stats. If you appreciate quick sessions, you can set up auto mode with your own stop limits. Personally, I prefer controlling each spin, but auto spins can be handy if you’re looking to keep momentum going without constant clicking.
Why RTP And Volatility Matter
In my view, the RTP rating of 96.4% is quite solid, meaning you won’t face a huge edge from the house. Some studios give casinos the option to lower or raise that number, but that doesn’t apply here, so you’re unlikely to stumble into a secret downgrade. If you want a slot that is above average in theoretical return, 123 Boom! offers that cushion.
The volatility is pegged as high volatility, so big hits won’t necessarily appear every other spin. For me, high risk can be thrilling when chasing that x14,827 top payout, yet it can also drain a bankroll if you’re unlucky. If you’re new to bigger-swing games, I would suggest having at least 500 bets set aside. That amount can help you ride out losing streaks and still stand a chance of tapping into the more substantial prize chains.
Free Spins With Explosive Gains
You can set off the Free Spins when you gather three or more Scatter symbols (depicted by cannons) after a sequence of Cascading Reels finishes. As soon as the free round begins, your multiplier jumps to x2, then climbs by 1 with each explosive cascade you trigger. There’s no hard cap on how high it can go, so you might see it soar if your luck stays hot.
I believe the real kicker is the way each scatter fires a cannonball Wild onto the grid, potentially blowing up adjacent symbols to form new combos. After your chain of wins finishes, the next scatter in line fires again, dropping another wild. The extended chain reactions can feel pretty satisfying, especially if multiple scatters keep popping in. In my experience, that’s when the progressive multiplier can jump to impressive heights. Once you run out of collected scatters, the feature ends, which can be a bit abrupt if you only gathered a few of them.
Other Surprises On Deck
• Sliding Cannonball Wild: If you spin and don’t see any immediate win, a cannonball wild might slide into place and blow up symbols one by one, hopefully creating a payout. This can reverse a losing spin into something more positive.
• Cascading Reels: Each time you land a winning combination, the contributing icons explode off the board, letting fresh symbols slide in. This can keep chaining, leading to multiple wins on a single paid spin.
• Scatter symbol: Represented by a big cannon image, it’s key to triggering the free spins. A batch of three or more sets you on the path to that bonus round.
• Multiplier Potential: In base play, you won’t see a large multiplier, but in free spins, it starts at x2 and rises with every chain reaction. You can rack up some good returns if it climbs enough.
