123 Boom Review

Look and Feel

123 Boom is an online slot game released in November 2020 by Relax Gaming, although the slot was created by their associate 4ThePlayer. This is a pirate-themed slot with plenty of swashbuckling, timbers being shivered and mainbraces being spliced … whatever all that means.

This game has a feature called ‘Slot Slider’. This is like the avalanche feature that has been used in a countless number of slot games. Here the symbols ‘explode’ when they feature in a win and the remaining symbols then slide along to the left. New symbols then slide in from the right to fill in the gaps. This can trigger new wins and according to the game’s instructions you can ‘win up to 107 explosive wins!’ – we have no idea why this maximum limit has been set at such an odd number.

The game also has the ‘all ways pay’ feature and because it has a bonus row (four rows as opposed to the habitual three) it has a total of 1,024 possible paylines. If you’re ready to take to the high seas and fancy the chance of winning a few pieces of eight then keep reading our 123 Boom review.


Alas, me hearties! If you go hunting around the seven seas in 123 Boom for a progressive jackpot you will not be unearthing much in the way of treasure for the game does not have one! You can still win up to 14,827 times the size of your bet though if you are fortunate enough.

Play for Real Money

The UKGC doesn’t take too kindly to pirates or slots offered for free or for play money at online casinos that are licensed by them. You can play 123 Boom for real money though at plenty of places, including Video Slots. This site has all the games you could possibly want to play, plus some decent bonuses too, so make sure you pay them a visit.


The explosive fun with 123 Boom starts as soon as you select the size of your bet. The can be as low as £0.10, or as high as £20.00. Wins are paid in relation to your bet size in line with the table below. Wins must consist of at least three consecutive identical symbols on the reels commencing with the left-hand reel. The position of the symbols on each reel does not matter.

Three or more cannon bonus scatter symbols will trigger this game’s bonus feature. Every exploding win now increases the value of a win multiplier by one. The scatters will also fire ‘Cannonball Wild’ symbols onto the reels to increase the chances of winning. Explosive wins can continue up to a maximum of 107. Once the scatters have been used and explosive wins end then the feature comes to an end.

If you do not land a win there is always the chance of Cannonball Wilds sliding in to create one. All wilds substitute for all other symbols aside from the cannon bonus scatter symbol.

The ‘Slot Slider’ aspect as mentioned above is optional as there are two modes:

Slide Spin – reels spin from right to left and pay left to right

Top Spin – reels spin from top to bottom and pay bottom to top

The game starts in slide spin mode but you can change the mode whenever you wish.

Graphics and Sounds

There’s a ‘retro slot’ feel to this game and we don’t know if this is intentional or not. This slot looks like one a bigger studio might have put out about a decade ago, but as the appearance of the game doesn’t affect the gameplay that doesn’t really matter. If you play slots for ‘eye candy’ appeal though doesn’t expect this slot to thrill you.

When resting you can hear the sounds of a pirate boat creaking and the waves rolling. Once you start the reels rolling a musical pirate theme erupts and adds to the pirate-y atmosphere. Winning symbols also explode with some gusto!


Okay, so when it comes to new online slots in 2020 this is not the most advanced slot we have ever seen, but it’s certainly worth a few spins if only for the ‘side spin’ feature. Things do warm up considerably though if you manage to trigger the bonus feature, although then it’s a little hard to figure out what exactly is going on.

That’s our view, anyhow. If you want to make your own mind up try 123 Boom at one of our many recommended casinos.


Q. If this online slots game is by 4ThePlayer, why is it released by Relax Gaming?

A. Relax Gaming is an aggregator as well as a software company. This means other companies, like 4ThePlayer, sign up with them so that their games are distributed among all casinos already supplied with Relax Gaming’s games.

Q. Ahhhh – I loves pirate slots! Any more you can recommend?

A. Hold on to your parrot as there are dozens of pirate-themed slots all over the internet. You might like to try Hook’s Heroes from NetEnt, Kingdom’s Rise Captain’s Treasure by Playtech or Blackbeard’s Bounty by Habanero.

Q. Not heard much about 4ThePlayer. Any other decent titles from them?

A. 4ThePlayer have a theme where all their slotting titles contain numbers. You could give 1 Left Alive, 2 Gods Zeus v Thor, 6 Wild Sharks or 9k Yeti a few spins if you’d like.
