Lucky Clover Riches Slot by PG Soft

Every spin runs a dual lottery inside the clover symbols. Lucky Clovers land randomly on the grid and stick there until the spin resolves. Once all symbols settle, each Clover flips to reveal one of two outcomes: a Level-up, which transforms every symbol on the board into the next higher-paying tier, or a Multiplier between x2 and x20 applied to all wins. Two Clovers on the same spin each resolve independently, so you might get a Level-up that upgrades the entire paytable and then a x15 multiplier on top of whatever that upgraded board pays out. Buy the free spins directly if you want to skip straight to where this mechanic gets aggressive.

And it does get aggressive. Free spins award 15 rounds from three scatters (each extra scatter adds 2 more), but the key difference is structural: every single free spin starts with three Lucky Clovers pre-placed at the top of the reels. Three reveals per spin, guaranteed, for the entire bonus. So each free spin gets three independent Level-up or Multiplier outcomes before payout. A string of Level-ups across consecutive spins keeps pushing the symbol hierarchy higher, meaning the pay anywhere wins that land are connecting with symbols worth several tiers above where they started. Stack a few multiplier reveals on top of that elevated paytable and the 7,500x ceiling starts making sense. Retriggering is possible too, though the base 15 spins with triple Clovers already packs plenty of variance.

The Irish luck theme runs deep green across everything - emerald reels framed by dark wooden pub walls, copper lanterns hanging overhead, clover patches growing along the base of the grid. Eva, the pink-haired elf in a green top hat, watches from the side. Symbols are all pub fare: pints of green beer, gold harps, horseshoes, a pot of gold for the scatter, with card royals rendered in matching shamrock-green lettering. The sticky mechanic means winning symbols stay lit on the grid while non-winners clear out, so big spins build visually across the board position by position until the clover reveal resolves everything at once.
