Boost It Slot: Demo Play, Review, Casinos List

Boost It has been made by STHLM (published on Feb. 20, 2018), which is a Medium volatility, 243 betlines (fixed) slot. The maximum win equivalents x2000 and the RTP equivalents 97.0 %. When it comes to the bonus features, this game has these: Wild, Multiplier.

Art‑Deco Jewels On A 5×3 Grid

Boost It greets me with polished gold frames, black lacquer, and a reel set that feels lifted from a 1930s ballroom. STHLM Gaming released the slot on 20 February 2018, so it is not brand‑new, yet the look still pops. Under the sheen sits a classic 5‑reel, 3‑row engine that pays left to right across 243 Ways rather than fixed lines, a format I usually like because it removes payline confusion. The theme leans hard into Jewels and Gems; top symbols are a large white diamond, a red “7”, and a lucky green clover, all drawn with bright facets that stand out against the dark backdrop.

Stakes, Symbols, And Jazz‑Tinged Flair

Bets begin at €0.25 and climb to €100, so casual spinners and high‑limit fans both find a spot. The maximum hit reaches x2,000 the stake, which lands in the mid‑tier for modern games but still enough to pull a decent cashout if the grid cooperates. A lively jazz loop hums behind every spin; it is smooth, maybe too gentle for adrenaline chasers, though personally I leave it on because it matches the Art‑Deco vibe. I tested Boost It on desktop and two phones, portrait and landscape, and the interface resized without odd gaps, so the mobile version feels solid.

Payback And Risk Factor Reality

The posted RTP clocks in at 97 %, which slides nicely into the A‑bracket of my scale and beats many releases by a full point. STHLM never offered those sneaky variable RTP settings that plague some bigger studios, so the figure you read is the figure you get—still, I always double‑check the help file before real‑money spins. Officially the game sits in the medium bracket; in my sessions I’d say it leans medium‑low, but numbers don’t lie, it is medium volatility. That means wins drip in often enough to keep balance alive, yet a bankroll of roughly 200 bets remains wise if you want a steady shot at that x2,000 ceiling.

Wild Reels Light Up The Board

Every spin carries an extra horizontal “Booster Reel” above the main grid. When its pointer lands on Wild Reels, one full reel on the main set turns into an expanding Wild. The reel locks for that spin, substitutes for all paying symbols, and, in my experience, can single‑handedly rescue hopeless boards. More interesting, I’ve seen two Wild reels drop together; that is when the game suddenly feels high‑risk because six or seven medium icons can land at once. It does not trigger often, but when it does, even modest stakes can return tidy sums, so I always perk up the second I see the gold “W” banner glide into view.

Multipliers That Can Spike A Spin

The Booster Reel has two other stops, and both relate to raw winning power. Symbol Multiplier picks one random picture on the current board and multiplies any wins from that icon by x5—great when it targets diamonds, underwhelming when it chooses card ranks. Win Multiplier instead boosts the entire outcome by x2 through x10; snagging x10 alongside a five‑of‑a‑kind diamond line is pretty much the dream ticket here. What I like is that the slot lets these modifiers stack; I have witnessed Wild Reels plus a Win Multiplier together, and the math gets spicy fast. Because the feature fires right inside the base game, there is no need to wait for a bonus; every spin carries genuine head‑turning potential, and that keeps me seated longer than I planned more than once.

Extra Touches Worth Knowing

• Wild symbol: the regular red‑gold “W” substitutes in the usual fashion; if the Booster Reel calls for Wild Reels it stretches to fill the column, otherwise it stays single‑cell.

• Multiplier: the Win Multiplier from the Booster Reel adds x2‑x10 on top of any successful spin, and sometimes that single roll is all you need for a session’s profit.

• 243 Ways: Boost It counts every left‑to‑right icon path, so lining up hits is simpler than old 20‑line models, and I feel that lowers frustration.
