Released on 1 October 2026, Ghost Booster! GO Guaranteed introduces a distinctive bonus system to Play’n GO’s collection of online slots. Set inside a haunted mansion, the game follows Wispy, a friendly ghost who gathers valuable Coins and activates special rewards. Its main attraction is the GO Guaranteed feature, which establishes a minimum payout for the next Hold & Spin round. Players can increase this amount during ordinary spins, potentially securing a higher guaranteed result when the bonus begins. Alongside this mechanic, the Wheel of Spooks offers four fixed jackpot prizes, including a Grand award worth 1,000 times the total stake. Understanding how these features interact helps players distinguish genuine guaranteed payouts from ordinary random rewards.
Ghost Booster! GO Guaranteed is a five-reel video slot with four rows and 20 fixed paylines. Its visual design combines a cartoon-style haunted mansion with colourful supernatural characters, floating Coins and animated collection effects. The game uses traditional paying symbols alongside special Coins and Collector symbols that control its most important features. Play’n GO released the title as part of its Halloween 2026 collection, giving it a lighter atmosphere than the darker horror themes commonly associated with seasonal casino games. The animations also serve a practical purpose: they help explain when Coins are collected, when the guaranteed amount increases and when a bonus has been activated.
The game supports a theoretical maximum win of 5,000 times the total stake. Published game information lists a betting range of 0.20 to 100 currency units, although the actual limits depend on the casino and available game configuration. At a stake of £0.20, for example, a 5,000x result would equal £1,000. At £1, the same multiplier represents £5,000. These figures describe potential payouts rather than expected winnings. Reaching the maximum is exceptionally unlikely, and most spins produce much smaller returns or no winning combination. Players should also distinguish the game’s overall maximum from the separate prizes available through its bonus features.
A particularly important detail is the game’s return-to-player percentage, usually shortened to RTP. The documented configurations include 96.25%, 94.25%, 91.25%, 87.25% and 84.25%. The casino determines which available configuration is used, so the highest figure should never be assumed automatically. An RTP of 96.25% represents a theoretical return of £96.25 for every £100 wagered across a very large number of spins, rather than a prediction for an individual session. Ghost Booster! GO Guaranteed also features substantial payout variation, meaning that results can differ considerably between short playing sessions. The relevant RTP and available betting limits should be checked in the game’s information menu before wagering.
Coins are central to the ordinary gameplay. When between one and five Coin symbols appear without a Collector, Wispy gathers their displayed values and awards the corresponding amount. The Coins therefore function differently from standard paying symbols, because their individual cash values determine the collection payout. Their appearance can also create an opportunity for the Wheel of Spooks to activate. Importantly, collecting five Coins does not provide a better chance of triggering the wheel than collecting a single Coin. The wheel’s activation remains a random event, and increasing the number of collected Coins does not improve its probability.
The Collector symbol introduces another possible outcome. When it appears alongside one to five Coins, it gathers the values displayed on those Coins and awards their combined amount. For example, if three Coins show values of 1x, 2x and 5x the total stake, a Collector gathering all three produces an 8x collection reward. At a £1 stake, this would be worth £8. However, when a Collector appears without any Coins, it has a different function. Instead of awarding a collection payout, it contributes towards increasing the GO Guaranteed meter above the reels. This distinction is essential because only qualifying Collector appearances advance the minimum-win feature.
The number of Coins also determines whether the main bonus begins. Landing six or more Coins during a base-game spin activates Hold & Spin rather than an ordinary collection event. This creates three clearly different situations: smaller Coin groups can produce immediate cash collections, Collectors without Coins build the guarantee, and six or more Coins launch the respin bonus. Although these events share similar visual elements, they serve different purposes. Players can follow the displayed meter to understand their current guaranteed amount, while the symbols on the reels indicate which kind of reward or progression event has occurred. None of these outcomes requires a special timing action from the player.
The defining feature of Ghost Booster! GO Guaranteed is the meter positioned above the reels. It begins with a minimum Hold & Spin guarantee of 20 times the total stake and can increase to a maximum of 100x. The value increases through qualifying Collector appearances during the base game, with every two Collectors that appear without Coins advancing the guarantee by 5x. At a £1 stake, the starting guarantee represents £20, while the highest available guarantee corresponds to £100. The displayed value is a minimum award reserved for the next qualifying Hold & Spin feature, not an immediate addition to the player’s account balance.
When Hold & Spin begins, the game uses the guaranteed amount displayed at the time of activation. If the feature produces a smaller qualifying payout, the guarantee increases the result to the required minimum. For example, suppose the meter shows 60x when the bonus starts. At a £1 stake, that represents a £60 minimum. If the bonus produces a qualifying return of £38, the guaranteed mechanism raises the payout to £60. However, if the feature naturally awards £85, the player receives the higher £85 result rather than an additional £60. The guarantee therefore establishes a lower boundary for the feature’s return rather than providing a separate bonus on top of every result.
After the Hold & Spin feature concludes, the GO Guaranteed meter returns to its starting value of 20x. The progress is associated with the selected stake, so changing the bet does not simply transfer a previously accumulated guarantee to the new stake. This prevents players from building the meter at a small wager and then applying the same progress to a much larger one. The guarantee also has an important limitation: it covers the relevant Hold & Spin result, not all previous spins. Spending £100 while waiting for a bonus that eventually guarantees £20 would still leave an overall loss unless other winnings covered the difference. A minimum bonus payout should never be interpreted as guaranteed profit.
Hold & Spin starts when at least six Coins land during the same base-game spin. The triggering Coins remain locked in their positions, and the player receives three respins to collect additional symbols. Each new Coin that lands occupies another available position and remains there until the feature finishes. Whenever a new Coin or Collector appears, the remaining respin counter resets to three. This means that the bonus can continue considerably longer than three turns if qualifying symbols keep arriving. Conversely, a respin that adds neither symbol reduces the remaining counter, bringing the round closer to completion.
Collector symbols behave differently during Hold & Spin. Instead of remaining permanently locked like Coins, they gather the values of the Coins currently displayed and award the collected total. The Collector then disappears, leaving its position available for another symbol during a subsequent respin. For instance, if the locked Coins have a combined value of 18x and a Collector gathers those values, the resulting collection is worth 18 times the stake. Further Coins can still appear afterwards, allowing the feature to produce additional rewards. The interaction between locked Coins and temporary Collectors is especially important because repeated collection events can increase the total payout without requiring every position to be filled.
The feature ends when the respin counter reaches zero or all 20 positions become occupied by Coins. Filling the entire grid provides an additional prize of 250 times the total stake. At £0.20 per spin, that full-grid award represents £50, while at £2 it equals £500. The guaranteed minimum is checked against the qualifying Hold & Spin result, and the full-grid bonus is awarded according to the game’s settlement rules. If the collected amount is below the stored guarantee, the minimum is applied before the additional full-grid prize. Consequently, a completed grid can produce a substantial result through the combination of collected Coin values, the applicable guarantee and the separate 250x award.

The Wheel of Spooks is a separate bonus feature that can activate when Wispy collects between one and five Coins without a Collector appearing alongside them. Its activation is random, and the number of Coins in the collection does not determine the probability of receiving the wheel. This means that a spin collecting one Coin can activate the feature just as a spin collecting five Coins can. The wheel offers an instant prize rather than introducing another sequence of respins. It is also independent of the GO Guaranteed meter, so receiving a wheel award does not mean that the minimum Hold & Spin payout has increased.
There are four fixed prize levels on the Wheel of Spooks: Mini, Minor, Major and Grand. Mini awards 10x the total stake, Minor awards 25x, Major awards 100x and Grand awards 1,000x. At a £1 stake, these prizes correspond to £10, £25, £100 and £1,000 respectively. At £0.20, the same multipliers produce £2, £5, £20 and £200. The values are determined by the selected stake and do not accumulate progressively across different players or casinos. Although the prizes use familiar jackpot names, they are fixed-multiplier awards rather than progressive jackpots whose amounts grow through additional wagers.
The appearance of the Wheel of Spooks should not be used to estimate the likelihood of winning its different prizes. The displayed sections are visual representations and do not necessarily correspond to the mathematical probability of each outcome. A Grand prize worth 1,000x is therefore not equally likely simply because it appears alongside the other three prizes. The wheel’s animation also does not provide an opportunity to influence the result through timing. The outcome is determined by the game’s random-number generation system. Unlike the GO Guaranteed feature, which establishes a visible minimum for a future Hold & Spin round, the Wheel of Spooks provides no comparable promise that a particular prize level will be awarded.
Ghost Booster! GO Guaranteed combines three different types of rewards: ordinary line and Coin collection payouts, the guaranteed Hold & Spin feature, and fixed Wheel of Spooks prizes. These mechanics can create different results even when the same stake is used throughout a session. For example, a £1 wager might produce an 8x collection, a later Hold & Spin could reach its 40x guaranteed minimum, and a separate wheel activation might award the 25x Minor prize. Such examples illustrate how the multipliers work, but they do not suggest that these events appear regularly or in any predictable sequence. Each outcome remains governed by the game’s rules and underlying probabilities.
It is also important to distinguish the guarantee from the theoretical RTP. Even when the GO Guaranteed meter reaches 100x, the game still retains its mathematical house advantage over the long term. The meter does not improve the published RTP setting or guarantee that the feature will activate within a certain number of spins. Similarly, the 5,000x maximum win is an upper payout limit rather than a realistic target for a typical session. Players who prefer to monitor their spending can calculate the cost of their wagers in advance. For instance, 100 spins at £0.50 represent £50 in total stakes before accounting for any winnings. This makes it easier to keep bonus expectations separate from the actual amount spent.
As of October 2026, Ghost Booster! GO Guaranteed offers a recognisable Hold & Spin format with an unusual minimum-win mechanic that develops during ordinary gameplay. Its strongest distinguishing feature is the visible connection between qualifying Collectors and the guaranteed payout of the next respin round. The Wheel of Spooks adds four clearly defined prizes, while the 250x full-grid award provides another possible source of winnings. Before playing for real money, it is worth checking the casino’s available RTP configuration, stake limits and local gambling rules. The guaranteed minimum can protect the value of a triggered feature, but it cannot eliminate losses from earlier wagers or make the timing of bonuses predictable.
