Book of Piggy Bank

Book of Piggy Bank gives the classic book slot a money theme, with wads of cash, a purse, a gem and a safe on the reels. Spinomenal extends the usual layout to 6 reels and 3 rows with 10 paylines, so a full line pays six of a kind. Volatility is medium and the RTP is 96.14%.

The book is both wild and scatter: three to six of them pay 2x, 25x, 250x or 500x the bet and award 10 free spins. In each free spin, a random symbol becomes the expanding symbol and spreads across its reels whenever that creates a win, paid on top of the normal result. A bonus buy is available for direct access. Stakes run from €0.10 to €25, with a top win of €250,000, a big ceiling for a low maximum bet.

Premium symbols pay from as few as two on a line, while card ranks need three. Cash is the best symbol at up to 10,000 coins for six of a kind, followed by the purse, the gem and the safe. The A, K, Q, J and 10 ranks pay from 5 coins up to 300 coins for six.

• Wild-scatter: the book substitutes for other symbols and pays 2x, 25x, 250x or 500x the bet for three, four, five or six anywhere.
• Free spins: three or more books award 10 free spins.
• Expanding symbol: in each free spin, a randomly chosen symbol (never the book) expands when that forms a win, paid separately from the regular result.
• Bonus buy: skip straight to the free spins.
