123 Boom! Slot Review

Introduction to 123 Boom!

123 Boom! is a 5 reel, 4 row pirate slot with 1,024 ways to win and a very odd mechanic called Slot Slider. Instead of the reels always spinning top to bottom, you choose Slide Spin or Top Spin so symbols either move across from the right or drop down the screen. At first the motion feels slightly dizzy, yet once your eyes settle it adds a fresh twist to standard ways gameplay.

As someone who likes odd mechanics, I stuck with 123 Boom! longer than I usually would and it paid off. The maths model feels tight, with medium to high volatility and a hit rate around one in 3.5 spins, while the bonus tends to appear roughly every couple of hundred spins. With max wins of about 14,827 times stake on the table, the potential is there if the cannons behave.

Theme and Graphics in 123 Boom!

The theme in 123 Boom! hits you straight away, with transparent reels set over a top down view of rolling waves and two ships trading cannon fire around the grid. It is not clear who is pirate and who is navy, which suits the moody sea backdrop. Symbols carry that nautical feel and the soundtrack leans into swashbuckling territory, giving the whole slot a lively, slightly chaotic battle vibe.

Symbols and Paytable in 123 Boom!

Regular symbols in 123 Boom! cover all the pirate kit you would expect. On the lower side you see ship wheels, telescopes, maps, curved swords, pistols, piles of coins and treasure chests building the smaller wins. Premiums are the crew themselves, a fierce lady pirate and a bearded captain who pays up to twenty times stake for five of a kind when they line up across the reels in the right way.

Two special icons really matter in 123 Boom!. The cannonball acts as the wild, appearing on any reel and substituting for pay symbols. If a spin ends without a win and there is a cannonball on screen, it starts sliding in the direction the reels are moving, blowing away one symbol at a time until it either creates a combo or falls off the edge. The cannon scatter is your trigger for the main bonus.

How to Play 123 Boom!

Getting started with 123 Boom! is straightforward once you grasp the odd spin options. First pick your stake, from around ten pence up to twenty pounds per spin depending on operator settings. Then choose your preferred Slot Slider mode. In Slide Spin the reels move from right to left and wins count left to right, which feels closest to a conventional ways slot and was the mode I settled on for longer sessions.

Top Spin takes more adjustment, especially on mobile where the grid sits upright. Here the reels tumble from top to bottom but payouts count from the bottom row upwards, so at first you need to watch carefully to see what has landed. However, whichever mode you choose, payments still come from landing three or more matching symbols on adjacent reels anywhere on the layout, giving you the full 1,024 ways structure on each paid spin.

123 Boom RTP and Variance

In terms of stats, 123 Boom! sits in a comfortable band for regular play. Official RTP is around 96.4 percent, with medium to high volatility and over one thousand ways active on every spin. The hit rate of about one win in 3.5 spins matches what I felt during testing, with small chains popping quite often while the more explosive stretches, including long cascades and big multipliers, arrive less frequently but can reshape your balance.

The bonus does not arrive on every sitting, with the long term average roughly one trigger in a little over two hundred spins, yet the game keeps you involved through those sliding wilds and reaction wins. From a risk point of view 123 Boom! sits between grindy low volatility games and extreme high variance monsters, which suits me when I want shots at four figure times stake prizes without needing a bottomless session bankroll.

Free Spins and Bonuses in 123 Boom!

The key feature you see most often in 123 Boom! is the Sliding Cannonball Wild. When a cannonball lands and the spin ends without a win, the symbol starts moving in the direction the reels are sliding, blowing up one icon at a time and closing the gap behind it. Quite a few dead spins turned into tidy wins for me thanks to a last second explosion nudging a premium into place.

Every winning combination also triggers Explosive Wins, the game’s version of cascading reels. Winning symbols blow off the grid and the rest slide to fill the spaces, with new symbols entering from the side or top depending on your chosen mode. This can repeat many times from a single paid spin. During one session I had a chain of more than twenty reactions that started from a tiny four of a kind and escalated nicely.

The main bonus, often called the Cannon Bonus or Bonus Feature, triggers when you have at least three cannon scatters on screen at the end of an Explosive Wins sequence. Those scatters load a row of cannons which fire sliding wilds onto the reels one after another. Each explosion sequence increases an unlimited win multiplier that starts at x2, and with up to around fifty reactions per spin on the cards, hits approaching 14,827 times stake are possible.

123 Boom Review

Overall 123 Boom! feels like a slot that rewards a bit of patience and a taste for odd layouts. The Slot Slider modes and sliding wild bombs make it more engaging than a lot of generic pirate games, even if Top Spin can leave you slightly seasick at first. For me it works best in medium length sessions, hunting for those cannon driven bonus rounds that can swing your balance with one outrageous chain of wins.
