Ghost Booster! GO Guaranteed

Ghost Booster! GO Guaranteed is a haunted-house coin slot from Play’n GO, released on 1 October 2026. A spooky mansion stands on a hill under a full moon, twisted trees with glowing green vines frame the reels, and a raven watches from a branch. The host is Wispy, a friendly blue-white ghost who holds a plate of gold coins and has a real weakness for money. The game uses 5 reels and 4 rows with 20 paylines, the RTP is 96.06%, the volatility is medium-high and the maximum win is 5,000x the bet. Everything is built around coins, a Hold and Spin bonus and a guaranteed minimum prize.

Neon Ghosts And A Haunted Mansion

Play’n GO mixes cartoon horror with a little neon science fiction. The low symbols are card suits – clubs, spades, hearts and diamonds – drawn as glowing neon signs in green, pink, yellow and blue. The higher symbols are haunted objects: an old treasure chest with a skull lock and a ghostly candelabra with blue flames. The Wild is a crystal ball with the word WILD inside, and it can appear stacked on several positions of a reel. It substitutes for the regular paying symbols, but it does not take part in the Coin and Collector features. Above the reels, four tombstones show the jackpot values, and the GO Guaranteed meter sits in the middle. It is a perfect fit for Halloween without being too dark.

Coins, Collectors And Wispy

The Coin symbols are round gold medallions with a value printed on them. Possible values are 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 and 1,000x the total bet. In the base game, there are three ways they come into play:

• if 1 to 5 Coins land without a Collector, Wispy flies over and gathers them;
• if 1 to 5 Coins land with a Collector, you win the total value of all the Coins;
• if 6 or more Coins land, the Hold and Spin feature begins.

The Wheel Of Spooks

Every time Wispy gathers Coins, there is a small chance that the Wheel of Spooks appears. The number of Coins he collects does not change this chance. The wheel always awards one of four instant prizes: Mini 10x, Minor 25x, Major 100x or Grand 1,000x the total bet. After the prize is paid, the wheel disappears and Wispy goes back to his place next to the reels.

The GO Guaranteed Meter

This is the feature in the game’s name. When a Collector lands in the base game without any Coins, it is stored in the GO Guaranteed meter above the reels. The meter starts at 20x the bet, and every two Collectors push it up by 5x, up to a maximum of 100x. This value is the minimum you will receive from the next Hold and Spin round. If the bonus pays less, the meter tops it up to the guaranteed amount. After the bonus, the meter goes back to 20x. If you change your bet, the meter resets, but returns to its level when you switch back to the previous bet.

Hold And Spin

Six or more Coins start the Hold & Spin feature with 3 respins. Only Coins and Collectors can land, and each new one resets the count to three. Coins stay on the reels until the end, while a Collector that lands collects the values of all Coins on the grid at that moment. The round ends when the respins run out or every position is filled. Filling all 20 positions with Coins adds a bonus of 250x the total bet, and the GO Guaranteed value is checked before this full-grid bonus is added.

Our Spins In The Mansion

We played the demo at €1 per spin. Coins appeared often: on one of the first spins, three medallions worth 2x, 1.5x and 0.75x dropped onto the middle reels together, and on another, a 0.25x Coin landed alone and Wispy swooped in to collect it in a burst of blue flame. Another spin drew a glowing green payline across the reels for a small line win of €0.10. The best moment came when stacked crystal-ball Wilds covered most of the first two reels and the last reel, and the spin paid €4.10. Between spins, the screen reminds you that wins of up to 5,000x the bet are possible.

RTP, Volatility And Bets

The RTP is listed at 96.06% and the volatility is medium-high. Bets usually range from €0.20 to €100 per spin, and the top prize is 5,000x the bet. There is no bonus buy, but the game offers Hyper Spin by holding the space bar, a Fast Play mode and autoplay.

Final Thoughts

Ghost Booster! GO Guaranteed is an easy-going Halloween slot with a clever safety net. The Coins and Collectors keep the base game active, the Wheel of Spooks adds surprise jackpots, and the GO Guaranteed meter makes it worth watching every Collector that lands. It suits players who enjoy Hold and Spin games with a guaranteed payout.
