Mega Fire Blaze: Piggies and the Bank Slot by Playtech

Everything on the reels is money. Green banknotes and gold coins rain down over a royal-purple vault, the whole grid resting on a heap of bullion, while four Fire Blaze prize bars glow across the top in red, purple, blue and green. The picture symbols keep the joke running: a grinning pink pig in a top hat, a solid-gold piggy bank, stacked gold bars, banded dollar bundles, a purple wallet spilling coins and a blue safe, over ornate A-K-Q-J-10 royals. Two special coins drop into all that, flaming gold cash coins stamped with a value, and a red-star coin that carries the jackpots.

The first of its two signature features is built around a moving wild. When a Gold Wild lands tall enough to cover a full reel it locks as a Stacked Gold Wild and sets off respins. Each respin, that stack slides one reel to the left. Land a second full-reel gold wild and it holds where it is and restarts the respin count, so two can be creeping across the board at once. During these respins any cash coin on screen turns wild, and a whole reel of cash coins becomes a fresh Stacked Gold Wild of its own. It keeps going until a respin lands with no stacked wild left.

The second is the Mega Fire Blaze round, and this is the one worth chasing. Six or more coin symbols trigger it. The coins lock, each holding either a cash value or a Star, and every new coin that lands resets the respins. The grid grows as you go: some coins carry a key, and every two keys unlock an extra row beneath the standard three. Those lower rows pay heavier. A prize sitting on the seventh row doubles, the eighth row multiplies it five times, and any coin that reaches the ninth row converts into a Star. Star coins are where the four fixed prizes come from, Mini 20x, Minor 100x, Major 500x and Grand 2,000x the bet, and each can be won more than once inside a single feature. These are set amounts, not the climbing network pool that Piggies and the Bank PowerPlay Jackpot dangles.

Scatters only matter for the free games. Three or more award eight spins, and here every Gold Wild that drops expands to fill its reel and fires the respins by itself, so the moving stacks turn up far more often than in the base game. Three scatters again during the round add another eight. No bonus buy and no ante, so both features have to arrive on their own, the same deal across the rest of the Mega Fire Blaze lineup.
