Great Ghosts! Slot by Pragmatic Play

Four glowing crystal balls hover above a blue-lit haunted mansion parlor, and they're not just decoration. Great Ghosts! from Pragmatic Play builds its entire bonus structure around those orbs, each one tied to a different scatter color and a different respin modifier. Blue feeds the Upgrade modifier. Pink powers the Mystery modifier. Green charges the Extra modifier. Land enough of any color and the Ghost Respin triggers with whatever modifiers you've filled - or buy your way in at 300x for all three active at once.

The base game runs on a standard 5x4 grid with 50 paylines, but the respin is where the architecture changes. When Ghost Respin starts, regular symbols vanish. Only blanks and money symbols remain on the strips, each carrying a random value from 0.6x to 1,250x your base bet. You get 3 respins that reset every time a new money symbol lands. Hit 8 money symbols and a fifth row unlocks. Keep going through 12, 16, and 20 symbols to build up to a full 5x8 grid - doubling the original layout.

The three modifiers add layers on top. Upgrade drops 2x2, 3x3, or 4x4 frames onto the grid and boosts every money symbol inside. Mystery assigns a single random value to all pink money symbols for the rest of the round. Extra just tosses additional money symbols into empty positions. Getting all three active at once during a good run is how the game reaches its 40,000x ceiling.

Pragmatic Play also built in one of their more aggressive ante bet systems here. Normal mode is the standard 20x multiplier. ANY 3 mode costs 5x the normal bet and guarantees the respin triggers if three or more scatters of any color appear. ANY 2 cranks that to 25x the normal bet, guaranteeing a trigger on just two scatters. At that price, you're essentially paying for near-constant bonus access, though whether the math justifies it is another question entirely.

Visually the game leans playful rather than dark. The ghost characters are cheeky elderly figures in golden portrait frames, not horror material. Card values 9 through Ace fill out the lower end of the paytable, with Wilds paying 1,000 coins for five across a line. The cartoon aesthetic keeps things light, but the expanding grid and triple-modifier stacking give the respin genuine depth for a payline slot.
