Ghost Booster Slot Review
Down to the last respin. Several empty spaces still on the grid. Then a new Coin dropped in, the counter reset to three, and Wispy the ghost floated across and collected the values already showing – pushing the Hold & Spin comfortably past the 50x guaranteed minimum. That one recovery gave the session its shape, and it’s that moment that best captures what Ghost Booster does differently to most coin-collect slots: the outcome was never going to be zero.
Play’n GO’s haunted casino slot runs the familiar Hold & Spin format through a filter that changes its risk profile. The GO Guaranteed Meter builds a minimum bonus payout before Hold & Spin even triggers, so every feature starts with a floor rather than a blank page. That idea – visible progress toward a protected minimum – gives the base game a longer-term purpose that most coin-collect titles skip entirely. Medium volatility and a hit frequency of around one in two make the overall pace accessible rather than punishing.
Ghost Booster Base Game
Ghost Booster plays on a 5-reel, 4-row grid with 20 fixed paylines. The visual design leans into a cartoonish haunted casino aesthetic: neon greens and purples, grinning pumpkins, cobwebs, and cheerful ghost characters. It’s more Halloween party than horror film, with a light spooky audio bed during standard spins that strengthens noticeably when Coin collections or feature activations occur.

Wild symbols substitute for all standard paying symbols. Coins and the Collector Bag sit outside the Wild’s substitution range, which keeps the bonus-focused symbols distinct and easy to track on the reels.
Standard spin activity feels genuinely active even when payouts are modest. Wins arrive regularly enough that sessions don’t stall, though the emphasis is clearly on the Coin and Collector Bag symbols rather than payline combinations. Quieter stretches exist, but the base-game hit frequency keeps them from becoming extended dry runs.
Coin Symbols
Coin symbols carry individual multiplier values ranging from 0.25x to 1,000x the total bet. The full value range is:
0.25x, 0.5x, 0.75x, 1x, 1.25x, 1.5x, 1.75x, 2x, 2.5x, 3x, 4x, 5x, 7.5x, 10x, 12.5x, 15x, 20x, 25x, 37.5x, 50x, 75x, 100x, 1,000x.
Landing one to five Coin symbols alongside the Collector Bag in the base game pays the combined total of all visible Coin values immediately, with no feature round required.
Wispy the Ghost and the Collector Bag
When one to five Coin symbols land without the Collector Bag present, Wispy the ghost collects the stray Coins. Each collection feeds the GO Guaranteed Meter (see below) and carries a small chance of activating the Wheel of Spooks. Watching for that secondary activation gives the base game an additional layer of attention.


Ghost Booster Bonus Features
GO Guaranteed Meter
The GO Guaranteed Meter represents the minimum payout from any Hold & Spin feature. It starts at 20x the total bet and increases by one level (plus 5x) every time two Collector Bag symbols are collected in the base game. The meter climbs in steps – 20x, 25x, 30x, 35x – up to a maximum of 100x the total bet.
When a Hold & Spin feature completes, if the total Coin value accumulated during the feature falls below the current Meter level, the Meter value is paid instead. After a payout, the Meter resets to 20x. Changing bet size during base-game play also resets the Meter to the new stake’s starting level, so the progression is stake-linked.
Hold and Spin
The Hold & Spin feature triggers when six or more Coin symbols land anywhere on the reels simultaneously. The feature begins with three respins. Only Coin symbols and the Collector Bag can land during Hold & Spin – standard paying symbols and Wilds don’t appear. All Coins that triggered the feature remain locked on the grid.
Each time a new Coin or Collector Bag lands during the respins, the counter resets to three. Coins accumulate until the counter runs out. Filling the entire grid with Coins awards a 250x total bet bonus on top of all visible Coin values.
If the Collector Bag appears during Hold & Spin, it collects the values of all Coins currently locked on the reels. After collection, the locked Coins remain in place and the counter continues. This can meaningfully extend the value of a session if the Bag appears late in the feature when Coin values have had time to accumulate.

Wheel of Spooks
When Wispy collects one to five Coin symbols without the Collector Bag landing, there’s a small chance the Wheel of Spooks activates. The player spins the wheel to win one of four instant prizes:
- Mini: 10x total bet
- Minor: 25x total bet
- Major: 100x total bet
- Grand: 1,000x total bet
The number of Coins that Wispy collected doesn’t influence activation probability or which prize segment the wheel lands on. After the Wheel resolves, Wispy returns to the base state and normal spins resume.

Our Honest Verdict
The base game keeps things moving without asking for much patience. Payline wins arrive at a fair clip, and there’s enough happening with Wispy’s collections and the climbing Meter to prevent sessions feeling empty between features. What Ghost Booster doesn’t deliver is a rich base game in its own right – when Wispy, the Wheel of Spooks, and the Meter all stay quiet, those 20 paylines feel fairly plain.
Hold & Spin carries the game, and the Collector Bag is what makes the feature interesting rather than just mechanical. Landing one mid-feature – collecting the accumulated Coin values and letting the counter run on – is the moment Ghost Booster builds toward. The Wheel of Spooks is the lighter attraction: infrequent, low control, and liable to land the Minor when the Major and Grand segments are clearly in view.
The GO Guaranteed Meter is the genuinely distinctive piece. Raising it to 50x or above before Hold & Spin triggers changes the feel of the feature entirely – the early weak respins don’t carry the same sting when there’s a minimum floor already established. It’s a more accessible take on the Hold & Win loop than something like the Money Train series, where a disappointing feature outcome has nowhere to land. Here, the minimum absorbs some of that disappointment by design.
At 96.25% in its default configuration – though operators can run lower variants down to 84.25% – the RTP is around industry average. The 5,000x maximum win is a comfortable ceiling for a medium-volatility title: not a standout headline number, but meaningful when the 1,000x Coin or Grand Wheel prize lands. Play’n GO haven’t tried to make Ghost Booster into something it isn’t. It’s a focused, accessible coin-collect slot that suits players who want visible progression and a safety net under the bonus, rather than raw volatility and a theoretical extreme payout.
The cartoonish haunted casino identity holds up independently of any seasonal association – the GO Guaranteed system, Wispy’s interactions, and the Wheel of Spooks are strong enough to work outside Halloween. Ghost Booster scores 7.5 out of 10. The GO Guaranteed Meter earns it, even if the standard payline gameplay doesn’t always hold the room on its own.
