It’s All About Big Bass Bonanza from Pragmatic Play

Regardless of your angling skills, with Big Bass Bonanza you have the chance to experience the thrill of fishing for a big catch! With 4/5 volatility and an RTP of 96.7%, it’s easy to see why Big Bass Bonanza is such a high-roller at Casumo and one of the most sought-after slots in our game browser

Due to its success, Pragmatic Play released a Megaways version, Big Bass Bonanza Megaways on November 17th. This newest version is sure to make a splash among slot-fishing fanatics with its 46,656 potential ways-to-win.

Pragmatic Play CEO Julian Jarvis says that the new addition to the Big Bass Bonanza collection brings, “high-volatility excitement to the underwater adventure that we know so well.” 

But before we get too carried away by the new kid on the block, we wanna shine the spotlight on Big Bass Bonanza, an exceptionally well-loved slot with gripping bonus features that come to the surface during free spins.

Playing Big Bass Bonanza


Besides the standard symbols (10, J, Q, K, A), there are several high-value symbols that come in the form of a tackle box, fishing reel, and bobber. If you’re not familiar with fishing terms, a bobber is what keeps a hook from sinking. As the most valuable symbol, think of it as the one that could “keep you afloat” if you land three or more on a payline. The symbol with a bass on a hook is the scatter and the friendly fisherman is wild, although he only comes into play during the free spins. There are also symbols displaying green fish along with cash amounts, also important during free spins.

Free spins feature aka the Bonanza

Get three or more Scatters to activate free spins. If one of those fish symbols with a cash amount tugs on your line during the free spins, you might be about to catch a prize! If the Fisherman Wild appears on the same spin, you get to pocket the cash in the amount shown on the fish symbol. If the Fisherman turns up but there’s no fish for him to catch, try throwing a stick of dynamite and see if any of the symbols change over to money-making fish! 

Even better, if you have more than one Fisherman Wild on a single spin, each one collects the amounts from each cash-happy bass. So if you have two Fisherman Wilds on the same spin as two fish displaying €10 each, that’s €20 per Fisherman, or a total of €40 for that spin. A meter at the top of the reels collects Fisherman Wilds, introducing a new multiplier every four Fisherman, up to a max of 10x for 12 Fisherman.
