Let’s get one thing out of the way first: there isn’t a single fish in this game.
Despite having “Big Bass” in the title, you aren’t going on a fishing trip. You’re staring at a sunny Italian restaurant. Basically, the studio took a standard “Book” slot and awkwardly glued their Big Bass progressive jackpot network to the top of it.
The jackpot is literally the only reason this specific game exists. But here’s the crazy part: the game tries to sell you a premium feature that completely turns off your ability to win that jackpot. Make it make sense.
Here is my breakdown of how it actually plays.
The Base Game is a Snoozefest
If you’ve played any “Book of…” slot, you already know the drill. It’s a 5×3 grid with 10 paylines. You’ve got two chef symbols that pay out if you land a pair, but everything else requires three of a kind.
The Book symbol is your best friend here, it acts as both your wild and your scatter. Honestly, without the Book, the base game is painfully boring. I played a short session and mostly just bled my balance. My very first spin was a dead spin with a single, useless Book teasing me. The only time I got anything back was when a Book swooped in to connect some cheap symbols. Without that wild stepping in, expect a lot of quiet, empty spins.
Free Spins: The Illusion of Choice
If you manage to land three Books, you trigger 10 free spins.
Here’s a little annoyance: right before the round starts, the game flashes a card on the screen like it’s “selecting” your special expanding symbol. It’s a total illusion. You don’t get to click or choose anything; it just hands you a symbol. I got the jar.
Once the spins start, standard Book rules apply. If enough of your special symbol lands, they expand to cover the whole reel and pay out across all 10 lines, even if they aren’t touching. My bonus round was a total rollercoaster. I had long, frustrating stretches of dead spins right in the middle and at the end. I technically walked away in profit, but only because I got lucky with a couple of big expanding hits. It is incredibly hit-or-miss.
The “Jackpot Tax”
Here’s a peek behind the curtain: this game is just a clone. You can find this exact base game under a bunch of different names (Oranje Jackpot, Brasil Jackpot, plain old Book of Chilli, etc.).
But having those four progressive jackpot plaques hanging above your screen comes with a nasty “tax” on the math. This game has an RTP (Return to Player) of just 94.50% and a max win capped at 5,000x your bet.
That’s pretty weak. Older games with this exact same layout (Ancient Egypt or Book of Vikings) cap out way higher, between 6,600x and 10,400x. Even within the same jackpot network, there are games offering a full percentage point higher in RTP. And if you don’t care about jackpots at all? A game released by the exact same studio in the exact same week (Thunder vs Underworld 250) has a 98.01% RTP.
You are taking a big hit to your wallet just to have those jackpot signs on your screen.
The Dumbest “Buy” Button in Slots
This brings me to the biggest contradiction of the game.
The progressive jackpot only drops at the end of a base-game spin. But, on the side of the screen, there is a “Buy Feature” button that lets you pay 100x your stake to skip the base game and go straight to the free spins.
Do you see the problem here?
If you buy the bonus, you are literally paying a premium to skip the only part of the game where you can win the jackpot. You are paying to turn off the one feature that separates this game from a hundred other, better-paying Book slots.
The Verdict: If you are going to play this game, absolutely do not buy the bonus feature. The most logical way to play is just to spin the base game on the minimum bet and hope you get lucky with the progressive jackpot. Otherwise, take your money to a standard slot with a better RTP.
