Boom Time Slot RTP, Details & Wager Limits
The Boom Time slot is played on 5 reels and has 1,125 ways to win. Wins are calculated by counting the number of consecutive reels starting from the leftmost reel with matching symbols. You need at least 3 matching symbols to form a winning combination.
Stakes range from just 10p up to £50 per spin, which is typical of a lot of Iron Dog Studio slots and caters to most bankrolls. Simply use the coins icon below the reels to adjust your total bet. You can also set up to 99 autospins if you’re outside the UK.
The Boom Time RTP is 96%, which is the industry average for an online slot. The provider has actually created 94% and 88% versions, so just double check you’re playing the right one when you load it up. You’ll find the RTP details in the paytable. In terms of volatility, it’s in the medium to high range.
The maximum win is 9,689 x your stake. The Free Spins feature will be your best chance of landing the top prize due to the multipliers in play and the Boom Time feature that fills the reels with gold bars.
Theme – a jazzy heist
The theme in the Boom Time slot game is all about a bank heist. The reels are set just outside a vault, which looks ready to be raided. The vault’s design reminded me of the film The Vault as it looks identical. The visuals are pretty simple, with symbols exploding from the reels when they are part of a winning combination.
When the Free Spins feature lands, you head inside the vault, with gold bars in the background to signal the riches on offer here. In terms of the soundtrack, it’s very jazzy, which I really enjoyed. It is quite repetitive though, so if you’re not a fan of jazz then you may be reaching for the mute button after a while.
On the reels, the A-10 Royals are the lower-paying symbols. These are joined by higher-paying banknotes and coins as well as 3 different bank robbers. The blue bank robber symbol is the most rewarding, paying 0.8, 1.5 or 5 x your stake for 3, 4 or 5 in combination.
The game has 2 wilds. A standard wild with a grenade as the symbol and an enhanced wild with TNT. Both substitute for all standard symbols.

Boom Time Mobile
Produced by Iron Dog Studio using the latest HTML5 technology, Boom Time has been optimised to be played on all devices including iOS and Android devices. I really like the way it plays in portrait mode on smaller screens and this is my preferred choice.
Boom Time Bonus Features
There are 5 bonus features in the Boom Time slot game. From tumbles, wilds and sticky wilds, to free spins and an exciting Boom Time feature, there’s a lot to take in. Let’s run you through everything, starting with how the tumbles work.
Tumble feature
When you get a winning combination, the Tumble feature applies. The winning symbols are destroyed and the remaining symbols tumble down to replace them. The destroyed symbols are replaced with random symbols. If the new symbols also form a wintering combination, they too will be removed from the reels to make way for new symbols. This continues until no new winners are formed.
Sticky Wilds
Sticky Wilds can appear anywhere on reels 2, 3, 4 and 5 as well as the Horizontal Reels during the base game or Free Spins feature. At the end of a tumble, it will explode alongside 2-5 symbols on the centre reels. This could lead to new winning combinations falling into place. This is what happens if 1 Sticky Wild appears. If 2 land, those symbols are converted to Wilds instead of exploding.
Free Spins feature
This feature will trigger if you land 3 or more Bonus Scatters in the base game. These symbols will appear on reels 2, 3, 4 or 5 only and not on the Horizontal Reels. Here’s how many free spins you could get initially:
| Bonus Scatters | Free Spins Awarded |
| 3 | 10 |
| 4 | 15 |
| 5 | 20 |
Enhanced Wilds come into play during this bonus round, and they substitute for all paying symbols. When the Enhanced Wild is part of a win, it can increase the multiplier by 1x or 2x or award up to 2 additional free spins.
What’s also important to note here is the Boom Time counter above the reels. Each consecutive tumble will move you along the progress bar, awarding multiplier increases and extra free spins as you progress.
Making it all the way to the end will award Boom Time. This will trigger the reels to fill with gold bars. Each gold bar will have a multiplier attached to it. This will pay and get added to your total win. Once Boom Time ends, the free spins will continue if you have any left.
Finally, there’s a Buy Bonus feature. Not available in the UK, you have 2 options:
- Buy 10 free spins for 76 x your stake.
- Buy 15 free spins for 144 x your stake.
Boom Time Review Summary – a well-rounded slot
Overall, I was pretty impressed with the Boom Time slot. It’s a very well-rounded game, with a fun Free Spins feature that includes wilds to boost the multiplier or award extra free spins. It’s not easy to fill the progressive bar in the Free Spins feature, but when you do, all hell breaks loose (in a good way) with gold bars filling the reels with multipliers for potentially huge wins.
While the soundtrack is a little bit like marmite, the max win potential of 9,689 x your stake is pretty good when you couple that with a 96% RTP and medium to high volatility. Some of the best UK slots tend to be maxed out in terms of volatility, so it’s nice to see that’s not the case here. For lovers of heist-related slots, this is certainly one to try. A job well done by Iron Dog Studio.
