Leprechaun's Secret Slot by Zillion Games

Three pots of gold above the grid track feature progress - DOUBLE (green), MULTI (red), and EXTRA (blue). Each fills as matching symbols land during base play. Completed pots stay active for the next Bonus Game, and all three can stack for a fully loaded round.

DOUBLE splits the screen into two 5x3 grids. Bonus coins duplicate across both fields, each running its own respin counter. MULTI assigns x2, x3, or x5 multipliers to individual coins during respins. Hit the same coin twice and multipliers compound - x2 followed by x3 gives x6, not x5. EXTRA extends the respin counter from 3 to 4 and resets to 4 with every new coin instead of 3.

The Grand Jackpot works differently here than in most Zillion titles. Collect 15 bonus symbols and the last one placed is the Grand (1000x) - it always arrives as the final piece. Major (100x), Minor (30x), and Mini (15x) tiers fill remaining positions. Buy Bonus skips the base game grind and triggers Hold and Ring directly, though progress bars still need filling through regular play first for maximum feature stacking.
