This week’s sweepstakes casino slot pick undoubtedly packs a punch — literally. Dynamite Trio by Booming Games is an explosive ride through gold-filled canyons, cartoon chaos, and one of the most entertaining Hold and Win features we've seen in quite a while. It’s sharp, fast, and full of big win potential and that’s what we love about this game.
If you like slots with escalating features, cheeky characters, and the ability to cash in big time, you’ll want to meet the trio behind the boom.
Dynamite Trio drops you into a sun-drenched canyon, with dynamite-laden reels and a scrappy prospector guiding the way. It’s everything you could imagine about miners looking for the riches.
The cartoon visuals strike a nice balance — clean and modern without going over the top in either direction. There’s a twangy, upbeat soundtrack rolling in the background to get your senses going, plus plenty of bangs every time something explodes on the reels.
It’s got a classic gold mining theme, sure, but this one feels fresh thanks to slick animations and a focus on chaotic, feature-rich gameplay.
Of course, everything’s wrapped in a playful style, but don’t let that fool you — this game can deliver serious wins that you can’t find in any other game.
Dynamite Trio uses a typical 5x3 reel layout with 20 fixed pay lines. You’re looking for matching symbols on adjacent reels from left to right, which is standard in most classic slot games. The base game wins come at a steady pace, with a hit frequency of around 1 in 4 spins, which we feel keeps the action moving.
As far as the symbols go, they stick to the western theme. The low-payers are your standard card royals such as the 10 through A, jazzed up to match the frontier vibe of the game.
The premium symbols, however, are what you’d expect to see in a miner’s toolkit. These include hatchets, lanterns, helmets, and gold nuggets. The prospector himself is the top-paying regular symbol, dishing out 20x your bet for a five-of-a-kind, which is surprisingly easier to get than you’d imagine.
You’ll also spot wilds on reels 2, 3, and 4. These fill in for anything except the scatters and do their job well — especially when they land alongside other high-paying symbols such as the lanterns or the prospector.
So far, so good. But we haven’t yet even talked about what makes this game shine.
The real action comes from the three scatter symbols you’ll want to collect — each one a stick of dynamite with a twist.
Boost (green). This symbol increases the value of all visible cash symbols on the grid. It can push base amounts up to 15x their original values which makes even small setups worthwhile.
Expand (red). Ready to expand the win area? This enlarges the grid to a 6x5 layout, giving you more room to land value symbols and boost your total payout.
Collect (blue). This one is a lot of fun as it sucks in every visible cash value on the reels and locks them in as a combined total, locking that number down before other features play out.
These scatters are used to trigger the game’s headline feature — Hold and Win. And depending on the combo of scatters you land on the reels, the bonus round plays out in 1 of 7 different ways.
This is where the game really explodes. Here’s the gist of this feature — land any one of the 3 3catters — or any combination — and the Hold and Win feature begins and you’re set for a wild ride.
The grid shifts focus and you get 3 bonus spins to start. Land any value symbol or new scatter during those spins, and the count resets to three. Every winning symbol locks in place as the rest of the reels continue to spin.
Remember the scatter symbols we mentioned? This is where those gems really matter—
Boost only? Every new symbol that lands can get juiced up for bigger payouts.
Expand only? You’ll get more room for bigger setups and land more and better symbols.
Collect only? Everything you see gets banked super fast.
Now, if you land all 3 of the scatters together, you trigger the Mega Bonus which is simply insane. This is the full package where the Boost, Expand, and Collect scatters work together, giving you more grid space, higher values, and a locked-in total that builds faster than ever. The screen clears at the start, and every symbol from that point is a chance to rack up serious GC or SC.
The feature ends when spins run out or the grid fills, whichever comes first. If you fill the whole thing, you’ll walk away with something truly big — especially with jackpots in play. Hopefully, you’re playing with SC when this happens.
The Hold and Win is the heart of the game where we found the biggest wins come at you; however, jackpots are just as fun and you'll see why.
During the Hold and Win feature, you’ll sometimes land fixed jackpot symbols which are the classic Mini, Minor, Major, and Grand. If you've played sweepstakes games before, there's a good chance you've seen these. The values vary based on your current bet, but they’re still always solid.
The max win for Dynamite Trio is a whopping 10,000x your stake. That’s more than enough to make a few fireworks feel worth the chase and definitely worthy of a screenshot.
And while hitting the Mega Bonus or Grand Jackpot isn’t exactly easy to land, the setup keeps you coming back for more with more chances at those bonuses.
Don’t worry, as even the smaller rounds can add up, and the range of bonus combinations adds some welcome unpredictability. When you keep spinning, you'll be amazed at what can rack up.
If you want to jump into the best part of the game, Dynamite Trio includes Bonus Buy options, which let you jump straight into the Hold and Win mode. There are 2 choices to select from—
Mystery Choice. You pay a set amount and get dropped into a random version of the feature. It could be a simple single scatter bonus or the full Mega Bonus if luck's on your side.
Mega Bonus Buy. Don’t want to see if luck is on your side? This costs more but guarantees all 3 scatters are in play. You’ll start with Boost, Expand, and Collect fully active—no waiting around and no funny business. It’s time to win.
These options are great if you’re more into the feature play and don’t want to grind the base game for a handful of Gold Coins. But they do happen come at a hefty price, and with the game’s volatility, returns aren’t guaranteed, either. So, buy the bonus with caution.
We all know that there’s no shortage of mining-themed slots out there. In fact, the theme is one of the more common ones because, after all, we're all hunting for that gold. But Dynamite Trio does enough differently to make it stand out from the rest of the crowd.
1. The Hold and Win variety is one of the best. You don’t just get one version of the feature — you get 7 and they're all great. That kind of flexibility makes the game feel fresh every time you trigger a bonus.
2. The Mega Bonus is genuinely exciting. When you land all 3 scatters, it feels like a big deal — and it is. That combo turns the game into a high-stakes grid-clearing contest where the payouts can go through the roof and that’s where it gets intense.
3. It’s fast and fun. You’re not stuck watching long animations or waiting for one rare trigger. Sure, those are fun when you want them, but not necessary. With a hit frequency of around 1 in 4 spins, something’s always happening, even between big bonuses.
4. The style works. The visuals are sharp, the theme is cohesive, and the sound design sells the setting without getting a bit annoying. It’s familiar, sure—but it’s polished, and that counts when we’re picking our game of the week.
Of course, there's plenty more to love about this game than just those, but you get the idea. We think you're going to find your groove and fall in love with Dynamite Trio as well.
Looking to strike gold this week? We are and that's why we're pinning this game as the game of the week.
Dynamite Trio gives you everything you want in a modern sweepstakes slot. From it's smart features, escalating payouts, and the kind of gameplay that makes each session feel different, this game is undeniably loaded to the brim with the good stuff.
If you're looking for something that's a little more on a the wild side, give it a spin, load up that dynamite, and see if the canyon’s got gold waiting for you.
