Book Of Piggy Bank Black Friday Slot Review
Heavy black drapes hang behind the reels, folded in deep vertical pleats, and a thick gold filigree border studded with rivets frames the whole grid. Gold coins drift across the frame like embers, while a dark vignette pulls the eye to the glowing centre. Book Of Piggy Bank Black Friday dresses its shopping-frenzy theme like a midnight sale at an upmarket pawnshop, and the presentation is doing a lot of the work here: strip away the velvet and what’s left is one of the most conservative Book layouts going, saved by a single smart change to the bonus round.
It’s a Spinomenal build in the familiar Book mould: a 5×3 grid, 10 paylines, one scatter wild that opens the free spins, and an RTP of 92.85%. The twist is that the expanding symbol re-rolls every single free spin rather than locking in for the round. The studio’s shelves are well stocked in this line, from 3 Piggies Cashout to Majestic King and Tiger Charms.
The Shop Floor: Symbols and Pays
All symbols pay left to right from the leftmost reel, and only the highest win on each line counts. Wins are multiplied by the bet per line. Ten fixed lines, no ways mechanics, no side bets: a win forms the way it has formed in Book games for a decade.
The paytable is split between shopping-themed symbols and the familiar royals, and the gap between the two halves is wide. The values below are the figures as the game prints them:
- Black Friday – two: 10, three: 100, four: 1,000, five: 5,000, six: 10,000
- Red Hat (purse) – two: 5, three: 40, four: 400, five: 2,000, six: 4,000
- Blue Gem – two: 5, three: 30, four: 100, five: 750, six: 1,500
- Safe – two: 5, three: 30, four: 100, five: 750, six: 1,500
- A – three: 5, four: 40, five: 150, six: 300
- K – three: 5, four: 40, five: 150, six: 300
- Q – three: 5, four: 25, five: 100, six: 200
- J – three: 5, four: 25, five: 100, six: 200
- 10 – three: 5, four: 25, five: 100, six: 200
The top of that ladder matters more than it usually would, because the expanding symbol in the bonus can be any of these. Five Black Friday symbols at line bet pays 5,000, and six pays 10,000. The royals pay pocket change by comparison, which is the standard Book-game shape.
Between the two halves sits the mid tier. The red hat purse and the safe both pay the same as the blue gem, so the theme symbols aren’t ranked by looks – the Black Friday logo is worth more than double everything else at the top end, and the gap only widens down the ladder. Six Black Friday symbols returns 10,000 times the line bet; six tens returns 200.
One symbol doesn’t appear on that list: the piggy bank book. It’s the wild, standing in for any symbol, and it’s the scatter too. What it pays and what it triggers are the next section’s business.
Scatter Wilds and the Free Spins Sale
The Scatter Wild Symbol
The book counts as any symbol when it substitutes, and three or more of them scattered anywhere on the slot pay on top of any line wins. The ladder is steep:
- Three scattered wilds – pays 2x and triggers 10 free spins
- Four scattered wilds – pays 25x and triggers 10 free spins
- Five scattered wilds – pays 250x and triggers 10 free spins
- Six scattered wilds – pays 500x and triggers 10 free spins
Scatter prizes are paid in addition to regular payline winnings, so a full-screen trigger can land two payouts at once. The bet per line carries into the round unchanged, and the same trigger that opens the round also extends it.
Free Spins and the Expanding Symbol
Every free spin assigns a fresh expanding symbol at random, and it can be any paying symbol except the scatter wild itself. That’s the twist. Where most Book games pick one symbol and stick with it for the whole round, this one re-rolls each spin, so a run of low-value expansions can be followed immediately by a screen-filling top symbol.
The expansion happens after the spin’s result is settled. The chosen symbol stretches across its reels to form new paylines on top of the existing ones, but only where doing so actually creates a win. It pays the paytable value across all active lines, and the winning symbols don’t have to sit on consecutive reels. Expansions count separately from the base result.
The order of operations is worth being clear on. The spin lands, any ordinary line wins are worked out and paid, and only then does the expanding symbol fill its reels. That means an expansion never costs you anything – it either adds a win or doesn’t fire at all – and a spin that looked dead on the reels can still finish with a payout.
The round retriggers. Three or more scattered wilds landing during free spins add another 10 spins to the tally, with no stated limit on how many times that can happen. Since the scatter wild is also the substitute, a retrigger spin can pay twice over: once through the scatter prize and once through any line wins the books complete.
One practical note on the bonus: a BUY button sits alongside the reels in the base game, offering direct entry to the free spins round without waiting on the scatters. The purchase price is shown on the button itself, so check it there before you commit.
Our Honest Verdict
Overall Rating: 6.5/10
Playing this is mostly a waiting game punctuated by ten spins of proper tension, and the per-spin re-roll is the reason anyone would pick it over the dozen other Book games on the same shelf. No round is settled in advance: a dreary run of royal expansions can turn on the last spin when the Black Friday symbol fills the screen.
That re-roll is the strength, and it’s a real one. The weakness is just as real: 92.85% is a poor return by any current measure, and the velvet drapes don’t change what that costs over a session.
It suits Book-game regulars who want the formula refreshed and can live with the price of admission. Anyone shopping purely for value will find better bargains further down Spinomenal’s aisle – this sale looks lavish, but the markdown is thinner than the gold trim suggests.
