Greentube launches Piggy Prizes: Ghost of Gambini with Super Lock & Spin

Greentube released Piggy Prizes™: Ghost of Gambini™ on 20 October 2026, a Halloween-themed slot that expands its Piggy Prizes™ series with the Lock & Spin mechanic. The title keeps locked-row prizes and adds a Super variant where Gold frames pay jackpots.

Main mechanics

The base combination uses chained coin and piggy-bank symbols on the reels that unlock when they appear alongside a Gambini or Ghost symbol on the centre reel. Gambini and Ghost symbols also act as Wilds. The Ghost of Gambini symbol can add coins, award jackpots and increase existing coin values.

Bonus features and special functions

The feature includes “Magic Spin”, which can first stop the centre reel with a visible Gambini symbol, and “Magic Rewind”, which can rewind the centre reel to land a Gambini and rewind non-winning reels over locked jackpot symbols. When a Gambini symbol lands in the centre, it launches a coin to one or both piggy banks. When a piggy bank reaches maximum size and bursts, the Lock & Spin feature starts with three spins, which increase to four if both piggy banks burst simultaneously. The frame type determines the payouts at the end of the feature.

When the Ghost of Gambini bursts a piggy bank, players enter Super Lock & Spin. Greentube states that during this feature only Gold Ghosts can land and that “every Gold frame awards a jackpot.”

“Piggy Prizes™ has a loyal following, and Ghost of Gambini™ gives those players a reason to watch the centre reel on every spin. The second Gambini symbol adds coins, boosts values and feeds the pigs, so the base game builds towards the bonus.

Super Lock & Spin then turns every frame into a jackpot, which gives the feature a clear top prize to chase. The Halloween setting makes it a strong title for operators heading into Q4.” — Richard Ganster, Director of Games Strategy and Games Portfolio Management at Greentube.
