Ghost Booster Slot
Play'n GO has produced no shortage of Hold & Win slots over the years, and Ghost Booster does little to break away from that increasingly crowded catalogue. Instead of introducing new mechanics, it delivers a lighter, family-friendly take on the familiar coin collection formula, replacing ancient temples and gemstones with cheerful ghosts, pumpkins and haunted houses. The presentation is charming enough, but this is very much a gameplay-first release that relies on established mechanics rather than innovation.
The game is played on a 5x4 layout with 20 fixed paylines and stakes ranging from €0.20 to €100 per spin. Medium volatility makes it less punishing than many recent Hold & Win releases, though that also comes with a more modest maximum win of 5,000x the bet. The default RTP is 96%, placing it comfortably around the industry average.
Coins drive almost everything that happens in Ghost Booster. Landing a handful of Coin symbols without a Collector allows Wispy, the game's resident ghost, to gather them automatically, while occasionally activating the Wheel of Spooks. This bonus wheel awards one of four fixed jackpots, ranging from a 10x Mini prize up to a 1,000x Grand, providing an extra source of rewards outside the main feature.

Collectors add another layer to the base game. Whenever they appear alongside Coin symbols, they immediately gather and pay the combined value of every visible coin. If a Collector lands on its own, however, it isn't wasted. Instead, it contributes towards the GO Guaranteed meter, a persistent feature that gradually increases the minimum payout awarded during the next Hold & Spin bonus. Every pair of collected Collectors raises the guaranteed prize by 5x, eventually reaching a ceiling of 100x the total bet.
The Hold & Spin feature itself follows a structure most slot players will instantly recognise. Landing six or more Coin symbols awards three respins, with every newly landed Coin or Collector resetting the counter back to three. Coin symbols remain locked for the duration of the feature, while Collectors repeatedly gather their values whenever they appear. Completely filling the grid awards an additional 250x prize on top of the collected coin values, while individual Coin symbols can be worth anywhere between 0.25x and 1,000x the bet.
One area where Ghost Booster feels noticeably lighter than many competitors is its overall feature set. There are no free spins, expanding reels or elaborate progression systems to chase. Instead, nearly every mechanic exists to feed into Hold & Spin or slightly improve its outcome. The GO Guaranteed meter is arguably the most interesting addition, giving sessions a small sense of progression even when bonus rounds fail to deliver.
Ultimately, Ghost Booster feels like Play'n GO playing things very safely. The spooky theme is colourful without ever becoming dark, the mechanics are straightforward to understand, and the guaranteed payout system adds a modest twist to an otherwise familiar formula. Unfortunately, with a relatively low max win and little beyond its Hold & Spin feature to separate it from countless similar releases, it struggles to leave a lasting impression. Players who simply enjoy classic coin collection slots may still find some entertainment here, but anyone looking for fresh ideas is unlikely to discover them in Ghost Booster.
