Leprechaun's Luck Slot by Playtech

Three separate bonus rounds is a lot for a slot this old, and that spread is the reason to spin it. Free spins, a pot-of-gold pick round and a wishing-well prize game all sit inside the same base game, each with its own trigger symbol and none of them leaning on the others.

The free spins are the pick of the three. Three or more pipe-smoking leprechaun scatters start the round: the little green fellow puffs his pipe, the smoke clears to show how many spins you've been handed, then he dances across the reels dropping wilds as he goes. Those wilds lock in place and stay put for the rest of the feature, so the board keeps filling with sticky wilds the longer the round runs. Land three or more rainbow pots of gold instead and the Rainbow Wealth bonus opens, a plain pick round for cash prizes. The wishing well fires its own prize game when it turns up. Three different ways in, three different payouts.

The wild is the gold "Leprechaun's Luck" clover logo, and it's the top symbol on the board. Five of them across a line pays 10,000x the line bet, not the total bet, so measure that number against a single line's stake rather than your whole spin. It covers every paying symbol: the Celtic harp, a pint of stout, red toadstool mushrooms and the Celtic-knotwork A-K-Q-J-10 royals.

This is the original, and it plays like one. The art is warm storybook Ireland, rolling green hills dotted with red-capped toadstools and daisies, a thatched cottage under a distant rainbow, the reels held in an ornate gold border. The jackpot plaque reads "Not available" in the free demo, which tells you the game's age. Playtech has since rebuilt it twice, once with coin mechanics as Leprechaun's Luck: Mega Cash Collect and once on a Megaways engine, both busier than this one. For the plain Irish-luck version with the dancing leprechaun and the locked wilds, though, this is the one that started it.
