Piggy Prizes Lock & Spin - Ghost of Gambini is a haunted-mansion slot developed by Greentube. The setting takes place inside Gambini's house, where stage-magic imagery is mixed with spectral effects, piggy banks, coins and fixed jackpot symbols. As an online casino title, it uses a distinctive reel structure made up of 15 individual reels arranged across a 5x3 display and connected by 40 win lines. Each position spins independently, while winning line combinations are evaluated from left to right.
The centre position has a specific role because the Gambini and Ghost of Gambini symbols appear only on the centre reel. Both act as Wilds and can substitute for regular symbols, with locked coin and locked jackpot symbols excluded from that substitution. Their appearance also interacts with the prize symbols already visible on the grid: the Ghost of Gambini can add extra coins or jackpot symbols and can upgrade an existing coin when another coin is placed on the same position.
Two base-game modifiers alter how the centre reel can behave. Magic Spin may trigger at the start of a round and makes the centre reel stop first with Gambini or Ghost of Gambini visible. Magic Rewind can move the centre reel backwards to reveal one of these two Wild characters. When one of them is already present, other non-winning positions may also rewind to reveal locked jackpot symbols. The rewind animation represents the predetermined outcome rather than a separate second result.
The feature system is built around two piggy banks positioned around the reels. Gambini may add a coin to one or both pigs, while Ghost of Gambini adds a coin to both. Filling a pig with a Gambini contribution starts Lock & Spin; filling it with a Ghost of Gambini contribution starts Super Lock & Spin. The two modes use ghost symbols and coloured frames, creating a feature sequence that is visually and mechanically linked to the haunted-house theme.
The visual identity combines a theatrical magician theme with a haunted-house setting. Gambini's mansion provides the backdrop, while ghostly effects and piggy-bank elements frame the 5x3 display. The layout is easy to distinguish from a conventional five-reel slot because each of the 15 positions is an individual reel. The centre position is visually important because it is reserved for Gambini, Ghost of Gambini and card symbols.
The regular symbol set mixes character and object imagery with playing-card icons. The named symbols include Chalice, Money and Clock Tower, followed by card ranks from Ace down to Nine. These symbols form the standard line combinations across the 40 win lines.
The special-symbol family includes Coin symbols, four named jackpot tiers, White Ghost and Gold Ghost symbols, plus Bronze, Silver and Gold Frames. The frames belong to the Lock & Spin sequence rather than the standard line-pay system. Their colour indicates the current frame level and determines how White and Gold Ghost symbols affect that position.
Magic Spin and Magic Rewind use reel motion as part of the visual feedback. Magic Spin brings attention to the centre by stopping it first, while Magic Rewind visibly moves a reel backwards to the position used by the predetermined result. During Lock & Spin, the main visual progression is shown through frame creation and frame upgrades, allowing the feature state to be read directly from the grid.
The feature architecture links the two centre-reel Wild characters with the piggy banks and the frame-based Lock & Spin modes. The table summarises the main interactions between these systems.

When Gambini lands, he may add a coin to one pig or to both pigs. Ghost of Gambini adds a coin to both pigs. The character responsible for completing a pig determines which feature is launched: Gambini leads to Lock & Spin, while Ghost of Gambini leads to Super Lock & Spin. If both pigs complete at the same time, the opening spin counter is higher than when only one pig completes.
In regular Lock & Spin, a White Ghost placed on an empty position creates a Bronze Frame. Landing in a Bronze or Silver Frame moves that frame up one level. If a White Ghost reaches a Gold Frame, it is transferred to another position where it can create or upgrade a frame. A Gold Ghost creates a Gold Frame immediately on an empty position and upgrades Bronze or Silver Frames directly to Gold.
The three frame levels are Bronze, Silver and Gold. In Lock & Spin, the feature can therefore develop through successive upgrades. When a Gold Ghost reaches an existing Gold Frame, it moves to an empty position and creates another Gold Frame. If every reel position becomes a Gold Frame, the feature ends. At the end of the sequence, the frames reveal their assigned prize symbols or jackpot tiers.
A Lock & Spin or Super Lock & Spin round that starts with three spins resets to three when a ghost lands; a round that starts with four resets to four. The game also contains a direct bonus-access menu with one option for Lock & Spin and another for Super Lock & Spin. This menu changes the route into the feature but does not alter the basic frame rules described above.
Piggy Prizes Lock & Spin - Ghost of Gambini combines the established 15-reel, 40-line structure of the Piggy Prizes family with a haunted-mansion theme and a Lock & Spin system based on frame upgrades. The centre reel acts as the mechanical hub because Gambini and Ghost of Gambini appear there as Wilds and also interact with the piggy banks, coins and locked jackpot symbols.
The base game is shaped by Magic Spin and Magic Rewind. Both modifiers focus on reel movement rather than adding a separate mini-game: one stops the centre reel first with a Wild character visible, while the other can rewind the centre or other positions to reveal feature-related symbols. This makes the centre character state relevant to several parts of the same round.
The main bonus distinction is between Lock & Spin and Super Lock & Spin. In the first mode, White and Gold Ghosts interact with Bronze, Silver and Gold Frames, allowing positions to be created or upgraded in stages. The Super version restricts the symbol set to Gold Ghosts, which means frame creation and upgrades move directly to the Gold level.
Overall, the game can be described through four linked systems: independent reel positions, centre-only Wild characters, piggy-bank triggers and frame progression. The artwork and mechanics use the same mansion-and-ghost concept, so the visual presentation directly reflects what is happening in the feature logic rather than functioning as a separate decorative layer.
