Irish Crown Slot by Pragmatic Play

Free spins build on a leprechaun upgrade system that rewires the paytable as the round progresses. Each time a leprechaun character appears on reel 5 during the bonus, the lowest remaining card royal permanently converts into a crown symbol for the rest of the feature. First visit removes the 10s. Second takes the Jacks. By the fifth leprechaun, every card rank is a crown, and crown symbols pay instant cash prizes - three on screen award 1x, scaling to 40x for nine. That escalating density is where the free spins round gets its teeth.

Crown collection runs in the base game too. Land 3 or more crowns anywhere and you pocket an instant payout. Hit 10 crowns on a single spin and the Big Money Bonus starts - crowns lock, respins begin, and each new crown resets the counter. Filling all 15 positions activates the Super Reel with prizes up to 5,000x. An ante bet at 1.25x your stake (lighter than the usual 1.5x Pragmatic surcharge) bumps scatter frequency, though the max win drops to 4,000x while it is active. The 100x buy option skips straight to 10 free spins if grinding scatters feels slow.

Face-down question marks land as mystery symbols and all transform into the same random paying icon - wilds excluded, so no substitution shortcuts there. Green meadows, rainbow arcs, and gem-studded golden crowns fill the visual side of things. Standard Irish dressing, nothing unexpected. But the leprechaun upgrade loop during free spins creates a progression curve that most collection-style games skip entirely - each reel 5 appearance flips the odds a little further in your favor, and by the back half of the round, crown payouts fire on almost every spin.
