- 10 win lines, a £500 jackpot and stakes from 20p to £2

Big Piggy Bank is a B3 category slot from Inspired Entertainment, played on 5×3 reels with 10 win lines, stakes from 20p to £2 and a £500 maximum win. The piggy bank theme carries into the Golden Bank Free Spins Bonus, where Cash symbols are collected and tokens build towards four jackpots. It is a different game from Bigger Piggy Bank, which has its own review.
Base Game
Cash symbols land on reels 1 to 4 and are only awarded when a Collector or Bonus symbol lands. Collector symbols land on reel 5 in the base game and the bonus, collecting the values on the Cash symbols in view. Wilds land on reels 2, 3 and 4 in the base game and the bonus, substituting for all symbols except the Collector, Bonus and Cash symbols. The Bonus symbol lands on reel 5 in the base game only.

Golden Bank Free Spins Bonus
Landing 4 or more Cash symbols with a Bonus symbol awards the cash values in view and triggers 8 Free Spins. +1 symbols each add one extra spin, and Collector symbols award the values on the Cash symbols in view.
Tokens collected during the bonus lead to four jackpots: 3 Mini tokens award the Mini Jackpot, 4 Minor tokens the Minor, 5 Major tokens the Major and 6 Grand tokens the £500 Grand Jackpot. The matrix resets after each jackpot, so jackpots can be awarded repeatedly in a single bonus.
Dual Wheel Gamble
The Gamble can be turned on or off. The left wheel offers 1.5x, 2x, 3x, 5x or 10x the win, and the right wheel offers the Golden Bank Free Spins Bonus. Green awards the prize, while red loses the win and returns to the base game.
Fortune Spins
Fortune Spins is played at £2 per spin from the Fortune Spins button, on reels made up of Cash, Blank, Collector and Bonus symbols only. Landing 4 or more Cash symbols with a Bonus symbol triggers the Golden Bank Free Spins Bonus, and a Collector collects all cash values in view.
Overall
Collector and Bonus symbols both land on reel 5 in the base game, and Cash symbols only pay when one of them appears. In the Golden Bank bonus, +1 symbols extend the spins and the token matrix resets after every jackpot.
