Book of Chilli – Big Bass Jackpot Bonanza Slot Review
Sunlight through arched windows, laid tables with white cloths, a teapot waiting at bottom left – and the reels hung on the trattoria’s back wall like a chalkboard menu, carved red wood and scroll finials and all. The room is the best thing Pragmatic Play has built here, and that’s the problem: this third serving of the Book of Chilli recipe spends its effort on the wallpaper while the paytable underneath it gets thinner.
The odd part is the name. Our Book of Chilli – Oranje Jackpot review called that game a nice room to wait in, and this is the same kitchen with a new sign – the Big Bass tag brings nothing fishing-related to the table. Underneath sit a 5×3 grid, 10 paylines, medium volatility, 94.50% RTP and four progressive jackpots. The recipe is familiar; the returns are the question.
Base Game & Features
Spins play out on a 5×3 grid with 10 fixed paylines. Winning combinations run left to right from the first reel, and where more than one combination lands on the same line, only the highest pays. It’s the classic book-slot layout, unchanged and unadventurous.
The paytable below carries the values from two matching symbols up to five.
- Male Chef – 1x for two, 10x for three, 100x for four, 500x for five
- Female Chef – 0.5x for two, 4x for three, 40x for four, 200x for five
- Chilli Sauce Bottle – 0.5x for two, 3x for three, 10x for four, 75x for five
- Chilli Toast – 0.5x for two, 3x for three, 10x for four, 75x for five
- A, K – 0.5x for three, 4x for four, 15x for five
- Q, J, 10 – 0.5x for three, 2.5x for four, 10x for five
That’s a thin ladder. A top symbol worth 500x is modest for the format, and the gap between the chefs and the royals is narrow enough that the mid-tier symbols rarely feel like an event. The two chefs are the only symbols that pay for a pair.
The Book of Chilli symbol does double duty as both scatter and wild, substituting for every symbol in the game. It’s also the best-paying symbol on the board, and its values are multiples of the total bet rather than the line bet.
- Five Book of Chilli symbols – 200x the total bet
- Four Book of Chilli symbols – 20x the total bet
- Three Book of Chilli symbols – 2x the total bet
Book of Chilli – Big Bass Jackpot Bonanza Free Spins & Jackpots
Free Spins
Three or more Book of Chilli symbols anywhere on the reels award 10 free spins. Before the round begins, one symbol is chosen as the special expanding symbol. After regular wins pay out, every instance of that symbol on a reel expands to cover all three positions.
The expansion pays on all reels, including non-adjacent ones, which is where the round’s real potential lives. A screen full of an expanded top symbol doesn’t need the paylines to connect.
Expansion only triggers when enough symbols for a win are present, so a stray single icon does nothing. The order of events matters here: regular symbols pay first, the expansion resolves second, and a book that lands as part of the trigger can still act as the wild while the round runs.
Retriggers are unlimited. Hitting three or more books during the round adds 10 more spins, and the chosen expanding symbol stays the same throughout – a retrigger lengthens the round, it doesn’t restart it.
Jackpot Bonus Game
The jackpots are the quiet engine of the title. At the end of any base game spin, the Jackpot Bonus Game can trigger at random, opening a pick screen where you reveal items until three carry the same jackpot name. That’s the one you’ve won.
Up to four progressive jackpots are available, and a stake of just 0.10 is enough to be eligible for all of them. There’s no way to win one during any feature, and no way to work towards one; it drops when it drops.
- Minor – the smallest of the four tiers
- Major – second tier
- Mega – third tier
- Grand – the top progressive
Buy Free Spins
The impatient route is always open. The free spins round, with its 10 starting spins, can be bought instantly from the base game for 100x the current total bet.
At the minimum eligible stake that’s a 10.00 outlay for the round. The chosen expanding symbol is picked just as it would be on a natural trigger, and the round plays out identically either way. Buying skips only the waiting.
Our Honest Verdict
Overall Rating: 6.3/10
Sitting in this trattoria is a pleasant way to lose money slowly. Spins are steady, wins are small, and the one reason to choose it over any other book slot is the progressive sitting quietly underneath – four tiers that can drop after any spin, from a 0.10 stake, without touching the feature’s payout.
That jackpot layer is what the game gets right, and it’s worth real money to small-stakes players. What it gets wrong is the plate in front of you: a 500x top symbol and 94.50% all-in are skimpy rations for a format that usually feeds better, and the Big Bass on the sign never turns up in the food.
If you like the expanding-symbol round and want a progressive running beneath it on a small budget, this is your table. If you want a full return and a ceiling worth chasing, the trattoria next door serves the same dish with more on it.
