Ghost Booster! GO Guaranteed

Ghost Booster! GO Guaranteed is a Play’n GO slot released on October 1, 2026, running on a 5-reel, 3-row grid inside a haunted mansion still stuffed with treasure long after anyone living last visited. A friendly ghost named Wispy works the reels for every coin he can reach, collecting loot and nudging the mansion’s features along. The win cap is 5,000x the bet.

Four fixed jackpots sit above the reels: Mini pays 10x the bet, Minor 25x, Major 100x, and Grand 1000x, based on the values shown at a standard stake.

The GO Guaranteed Meter

A GO Guaranteed meter sits above the reels throughout the base game, setting a floor on what the Hold & Spin bonus can return. Landing Collector symbols with no Coins alongside them climbs the meter a level for every two that gather, across five levels in total, raising the guaranteed minimum as it rises. If a Hold & Spin round ever finishes below that guaranteed value, the meter lifts the payout up to match it.

Hold & Spin and the Wheel of Spooks

Landing 6 or more Coin symbols triggers Hold & Spin with 3 respins, and every new Coin or Collector that lands resets the count back to 3, letting the round continue for as long as fresh symbols keep arriving. Collected coins stay locked in place on the reels, and the round ends once the respins run out or the grid fills completely. Separately, Wispy’s coin collecting can bring the Wheel of Spooks into play, a single spin that awards one instant prize from four ghostly jackpot tiers. The resident ghosts double as a progress tracker, counting collected coins across five visible levels, and climbing through them opens up the jackpot-wheel interactions tied to the Wheel of Spooks.

Ghost Booster! GO Guaranteed Review

The GO Guaranteed meter is a genuinely useful piece of transparency for a Hold & Spin format, since most games in this genre leave the bonus round’s outcome entirely to chance once it triggers, while this one lets players watch a visible floor climb throughout the base game and know exactly what the worst-case Hold & Spin result can be before it even starts. Tying that meter specifically to Collector symbols landing without Coins is a clever way to reward symbols that would otherwise feel like a near-miss, turning what could be a disappointing non-event into steady progress toward a better guaranteed outcome. Running the Wheel of Spooks as a separate system from Hold & Spin, rather than folding it into the same trigger, gives Wispy’s coin collecting two different payoffs to chase rather than one, and the five-level ghostly progression tying into both features gives the whole mansion setting a sense of forward motion that a flat coin-collection mechanic wouldn’t have on its own. The haunted mansion and ghost mascot keep Play’n GO’s horror theming approachable rather than genuinely unsettling, and Wispy’s enthusiasm for coins gives the whole feature set a clear, likeable throughline. RTP, volatility, and the bet range haven’t been published anywhere reliable yet, so this review will be updated once those figures are confirmed.
