Wild Booster Slot Review
A classic fruit machine stands alone on a lit stage, crimson banner arched between gold stars, the whole cabinet glowing on its golden podium while purple rays fan out behind it. Wild Booster hides its sharpest maths inside its oldest symbol: the wild, which can carry a random multiplier of up to 100x in the base game, not just the bonus. Strip that away and the fruit paytable beneath is almost shy.
Pragmatic Play run it at 96.47% RTP, high volatility, a 5,000x win ceiling and bets from 0.20 to 240 per spin, on a 5×3 grid with 20 paylines. Sister releases include Wild Wild Joker and 6 Jokers, two games that work the same glossy retro seam. The boost meter climbs every time you look away.
Base Game & Features
Wild Booster plays on a 5×3 grid with 20 fixed paylines. All symbols pay from left to right on selected paylines, starting from the leftmost reel on adjacent reels. Only the highest win counts per line, and wins on multiple lines add together.
It’s standard line-pay construction with no surprises in the plumbing. Values are expressed as wins in coins, with all wins multiplied by the bet per line, and the display can be switched between coins and cash. Here’s what each symbol pays as a multiple of the total bet:
- 7 – 2.5x, 5x, 30x for three, four, five
- Lemon – 1.25x, 2.5x, 15x
- Strawberry – 1x, 2x, 10x
- Orange – 0.6x, 1.25x, 7.5x
- Cherry – 0.5x, 1x, 5x
- Spade / Heart – 0.3x, 0.6x, 3x
- Diamond / Club – 0.25x, 0.5x, 2.5x
The symbol set is pure fruit machine: lucky 7s up top, then lemons, strawberries, oranges and cherries, with the four card suits filling the low end. The gap between the top symbol and everything else is wide, and the premium symbol does the heavy lifting on any sizable line win.
The wild appears on all reels and substitutes for every symbol except the scatter. That’s its whole job on paper. What makes it matter is what it triggers.
Wild Boost
On any spin where at least one wild lands, there’s a chance the WILD BOOST fires. When it does, a random multiplier is selected, and it applies to the win of every combination containing at least one wild. Combinations without a wild pay at face value. The twelve possible values are:
- x2, x3, x4, x5, x6 – the lower rungs
- x8, x10, x12, x15 – the middle of the ladder
- x25, x50, x100 – the top of the range
Because it can trigger in the base game, a single wild on a paying line carries far more weight than the paytable alone suggests. That’s the game’s whole pitch in one sentence. The scatter appears on all reels too, and three or more anywhere triggers the free spins round.
Wild Booster Super Boost Free Spins
Hit three or more scatters anywhere on the screen and the SUPER BOOST FREE SPINS round begins with five spins. Before it starts, you pick one of two options: MEGA BOOST or ULTRA BOOST. Both run a progressive feature that starts from a WILD BOOST multiplier and climbs three times by collecting scatters during the round, with special reels in play throughout.
The scatter count that triggered the round carries over as a head start on the collection meter, so a five-scatter trigger begins the round already close to the first tier. Free spins wins are added to the payline win, and the round’s total is awarded once it completes.
There’s a hard stop on top of it all. If the round’s total win reaches the 5,000x cap, it ends immediately, the win is paid, and any remaining free spins are forfeited.
Mega Boost
MEGA BOOST starts with five free spins and a x2 wild multiplier. Fewer scatters sit on the reels here, so the multiplier climbs more slowly. The ladder works like this:
- Start – x2 multiplier, five free spins
- 5th scatter – multiplier rises to x5, five more spins awarded
- 10th scatter – x10, five more spins
- 15th scatter – x100, five more spins, and the round can’t retrigger again
Retriggered spins are played after the previous batch ends, with the new multiplier applied to them. Once x100 is reached the round is done climbing.
Ultra Boost
ULTRA BOOST also starts with five free spins but opens at x3. More scatters are present on the reels, so the ladder climbs more readily, though it tops out lower:
- Start – x3 multiplier, five free spins
- 5th scatter – x6, five more spins awarded
- 10th scatter – x12, five more spins
- 15th scatter – x50, five more spins, and the round can’t retrigger again
The same rules on batches apply: retriggered spins queue behind the current set and run at the new multiplier. It’s a clean choice between the x100 ceiling through a sparser reel set and the more reachable x50 climb.
Buy Free Spins
The round can be bought straight from the base game for 75x the current total bet, with your choice of either boost option included. The number of scatters that hit on the buy is random, from three to five.
That scatter draw matters more than it sounds. A three-scatter buy starts the meter at three, while a five-scatter buy lands you one step from the first multiplier tier before a single spin has played.
There’s no mathematical premium for skipping the wait, either: the RTP on the buy is the same 96.47% as the base game. Patience and purchase are priced identically.
Our Honest Verdict
Overall Rating: 7.7/10
Every spin of Wild Booster is a bet on one symbol. The wild doesn’t just complete lines here, it multiplies them by up to 100x without warning, and that tension is the entertainment. For a high volatility game built on a single mechanic, it’s a tight, honest pitch.
Its best idea is the free spins fork: two genuinely different rounds, one betting on scarcity for x100, one paying in reachability. That’s a real choice, and it’s rarer than it should be. The weakness is the ceiling. 5,000x is a modest cap for a game this volatile, and the raw fruit pays underneath are thin enough that the boost isn’t topping anything up, it’s carrying the whole payout.
This is for players who like one mechanic done properly and don’t measure a slot by its maximum win alone. Anyone hunting four-figure ceilings will find it small. For everyone else, the show on that purple stage is worth a look.

What is the RTP of Wild Booster?
The RTP is 96.47%, and it’s the same figure whether you play the base game or use the Buy Free Spins option. -

Mega Boost starts at a x2 multiplier and climbs to x5, x10 and x100, with fewer scatters on the reels. Ultra Boost starts at x3 and climbs to x6, x12 and x50, with more scatters, so the ladder rises more easily but tops out lower. -

Can free spins be retriggered in Wild Booster?
Yes. Every time the multiplier ladder reaches a new tier, five more free spins are awarded. These are played after the current batch ends, at the new multiplier. Once the top multiplier is reached – x100 in Mega Boost, x50 in Ultra Boost – the round can’t retrigger again.
