Piggy Bank: 3 Pots Bonanza Slot by Evoplay

Three animated piggy banks sit above the reels, each tied to a bonus booster. Red (xFortune) randomly increases the values of 1-4 bonus symbols by 0.5x to 10x during each bonus spin - stacking on top of existing values rather than replacing them. Blue (xReels) doubles the playing field with a second independent grid where symbols mirror positions from the first. Green (xSpins) extends the bonus from 3 starting spins to 4.

The bonus round triggers when colored bonus symbols land, converting them to gold and locking them on a stripped-down grid. Each gold symbol carries a random value between 1x and 15x bet or a fixed jackpot tier. Landing any new symbol resets the counter. The GRAND jackpot at 3000x requires filling all 15 positions - and with xReels active, two separate GRAND prizes become possible across both fields.

xFortune is what separates this from similar hold-and-win titles. Instead of static values, bonus symbols keep growing as the round progresses. A symbol that started at 2x might end at 12x if hit by multiple xFortune boosts. Three buy bonus tiers are available: 35x for one booster, 44x for two, or 66x for all three.
