Rainbow Riches Rainbow Frenzy Slot by Light & Wonder

It belongs to the long-running Rainbow Riches stable, and the look is pure Irish postcard: a bright green meadow rolling up under a vivid double rainbow, wildflowers along the base, and a pot of gold tipped over to spill coins at the bottom. The reels sit inside an ornate silver Celtic-knot border. Symbols are the familiar set, a blue-glowing gold horseshoe, a golden harp, a red-capped toadstool, a green leprechaun top hat, the gold Rainbow Riches logo, and stylised card royals. The toadstool tops the standard pays at 100x for five. Two symbols act as wilds here, the plain Wild and the Leprechaun, and both substitute for everything except the Bonus scatter. The Wild also pays in its own right, climbing to 200x for five across a line.

Scattered across the reels you'll find Pots of Gold, cash symbols stamped with a credit value (2.00, 5.00 or 20.00 at a 1.00 stake). They do nothing on their own in the base game. They're fuel for later. Three or more Bonus scatters open the free spins, and that's when the Leprechaun wakes up. On any free spin where a Leprechaun lands, it pays out the value of every Pots of Gold on screen that spin. Land two or three Leprechauns and each one fires in turn, collecting the same visible pots over again. Ordinary line wins still pay alongside all of this.

There's a stronger version of the round too. Super Free Spins runs the identical setup but doubles every pot the Leprechaun grabs, so a board packed with high-value pots and a couple of collectors can stack up fast. Neither version retriggers, so the pots you have on the reels are the ones that count. No buy button, no jackpot tiers, just the cash collection driving the whole bonus. If you've played Even More Pots of Gold, the rainbow-and-meadow setting will feel like home, though this one puts the Leprechaun's collecting front and centre rather than a trail or wheel.
