Roving Clover Slot by Playtech

The Gold Clover is the one to chase. It only turns up on the fifth reel, the one dressed in deep red instead of glossy black, and the moment it lands it expands to fill that reel and kicks off the Clover Respins. Here's the roving bit: on the first respin the expanded Gold Clover holds its spot, then on every respin after it slides one reel to the left. Fresh Gold Clovers keep dropping onto the red reels while this plays out, so you can end up with two or three of them walking across the grid at once. The run finishes when the last one reaches the opening reel, five respins at most.

The green version does less but shows its face more often. A Green Clover fills any of the first four reels and stands in for every symbol, plain expanding wild work. And if a Clover just misses dropping into view, the reels shake and nudge it up or down to try to sneak it onto the board.

Everything else is old fruit-machine stock: blue grapes, a purple plum, cherries, a watermelon slice, a lemon, an orange, and a lacquered red 7 that tops the ladder at 1500x on a line. The clover WILD panels are ornate gold filigree, and they pay like that 7 when they line up. It all sits over a green field tiled with faint four-leaf clovers, bright and a little cornball in the best Irish-luck way.

Four progressive jackpots sit along the top, labelled Joker, King, Queen and Jack. Any spin can throw you into the jackpot game at random, a losing one included, and once you're in you flip cards and collect three of a kind to bank that tier. Don't fancy waiting on the Gold Clover? The Buy Feature purchases the respins outright, while the Gold Clover on More Reels ante quietly raises your odds of triggering them the normal way.
