Lucky Cloverland Dice Slot by Endorphina

An emerald forest does the heavy lifting here. The 5x4 grid sits inside an ornate gold Celtic border with a waterfall and ferns behind it, dappled green light everywhere, and a cheery red-bearded leprechaun in a green top hat tucked into the symbol set. Below him sit the lucky mid-tier icons, a foaming beer mug, a polished gold horseshoe, a four-leaf clover, and underneath those, the twist this version brings: orange, purple, blue and gold dice cubes filling the low-pay slots in place of the usual card values. Forty fixed lines pay left to right from the leftmost reel.

The leprechaun is the top symbol and lands stacked, so a full column of him on the right reels is where the base game pays best. Two special symbols sit above the rest. The pot of gold marked WILD subs for everything but the chest, and the treasure chest marked BONUS is the scatter, counting from any position, adding its own pay to whatever the lines return, and able to land stacked in both the base game and the bonus. Three or more chests open the free games.

That bonus is the reason to play. Three or more scatters award seven free games with a second random wild: at the start of the round the game picks one ordinary symbol at random and gives it full wild powers, substituting for everything except the chest, for the entire seven spins. So you play out the round with two wild types active at once, the pot of gold plus whatever got chosen. Draw the stacked leprechaun as the random wild and the round changes character completely. It retriggers on more chests and runs at the bet that triggered it.

Don't fancy the wait? The Bonus Pop button on the left buys those seven spins outright, the price scaling with your stake, and the bought round opens on a base spin that drops the three chests for you. Bonus Pop winnings can't be sent to the gamble afterward. That gamble is a card draw, pick one of four face-down cards to beat the dealer, double up to ten times running, with a joker that beats all and never lands in the dealer's hand. There are also three network mystery progressives, Grand, Major and Minor, drawn at random with a bigger bet improving your odds, though jackpot money is locked out of the gamble too. Plenty of St. Patrick's good-luck dressing, but it all comes down to which symbol turns wild for those seven spins.
