Dynamite Boost Slot Demo
Gold galore in the Dynamite Boost slot
I headed down the shaft in Dynamite Boost and straightaway the gold mine setting pulled me in. The 5x3 grid sits deep underground, with mine carts rattling along behind and glittering nuggets wedged into the rock face. Every symbol sticks to the theme: TNT crates, pickaxes, sacks of gold and hard hats, plus card ranks handling the cheaper hits. Swintt use bright, clear graphics and a warm colour palette that suits the light-hearted mining mood.
The game area is framed by rock and rails, while a separate horizontal Booster Reel hangs above the main grid, hinting that something extra is going on. Instead of a full musical track you mostly hear clinks, bangs and machinery, which makes the slot feel more like a working mine. On both desktop and mobile I found the presentation sharp, with no clutter in the interface to distract from the action.

Dynamite Boost RTP & variance
From a numbers point of view, Dynamite Boost is not a generous slot. The official RTP sits around 93.74%, which is well below what I am used to seeing on modern releases. Swintt pitch it at high variance, so you can expect streaky sessions with spells of dead spins broken up by bigger hits when features line up. The maximum win is capped at 2,500x stake, which feels modest given the rather lean return rate.
How to play Dynamite Boost
Getting started with Dynamite Boost is straightforward. You have five reels, three rows and 243 ways to win, with prizes paid for three or more matching symbols on adjacent reels from the left. I set my stake using the plus and minus controls beneath the grid, with limits between 0.25 and 25 per spin in the version I played. There is a large central spin button, with quick access to autoplay and max bet nearby.
Tapping the information icon opens the paytable and rules, which scale the displayed values to your current stake level. I like checking this first so I know what the higher symbols are worth and how the modifiers work. A small speaker icon lets you toggle the sound effects if needed. As always, I prefer keeping stakes modest at first, especially with a volatile slot where the balance can swing around very quickly.
How to win with Dynamite Boost
Winning in Dynamite Boost comes from lining up symbols on the 243 ways, backed up by wilds and modifiers. The TNT crate is the premium symbol, paying up to 8x for five of a kind in the base paytable. Below that you have a miner’s helmet, bags of gold, pickaxes and carts, which give mid-range wins. Low-tier payouts come from the standard 9, 10, J, Q, K and A icons, which tend to hit more often but for smaller amounts.
TNT also acts as the regular wild. It can stand in for all standard symbols to finish or improve a winning way, and it becomes even more valuable when the Booster Reel turns a full reel into wilds or drops a 2x2 wild block. The scatter symbol is the miner. It does not pay in the usual way, but instead displays numbers that combine to award free spins when you land at least three of them in view.
Because the top line payouts are not huge on paper, much of the real potential comes from combining stacked or expanded wilds with multipliers across several reels. I found that decent wins often arrived when a mid-range symbol like the pickaxe filled multiple reels while a 2x, 3x or 5x multiplier from the Booster Reel landed on the same spin. On drier runs you will mostly see smaller hits from the low symbols keeping the balance ticking over.

Dynamite Boost bonuses
The key selling point of Dynamite Boost is the Booster Reel feature above the main grid. On every spin this horizontal reel cycles through special icons that can affect one symbol, a single reel or the full layout. You can land Full Respin, single Respin, Expanding Wild, regular Wild and Multiplier icons. Full Respin can award up to five extra spins with the active modifiers locked in, while single Respin focuses on one reel for up to five attempts.
Expanding Wild turns the reel beneath its position fully wild, which can set up some heavy hits when paired with premium symbols. The regular Wild icon on the Booster Reel creates a 2x2 wild block in the central area, again great when ways line up. Multiplier icons add 2x, 3x or 5x to your total win for that spin. Free spins arrive when three or more miner scatters land; each shows a number between 3 and 20, and the sum decides how many spins you get. There is also a bonus buy, priced at 100x stake where permitted, which gave me quick access to the free spins during testing.

Dynamite Boost review summary
After a run of sessions on Dynamite Boost, I came away with mixed feelings. On the positive side, the Booster Reel fires very often and keeps the base game far more engaging than a standard 243-ways slot. I even hit a streak of 21 free spins from one trigger, which made for a lively bonus round. On the downside, the low RTP and limited 2,500x cap make it hard for me to treat this as a serious long-term option, though it can still be good fun for short, feature-chasing bursts if you manage your stakes carefully.
