Big Bass Hold and Spinner Megaways review
Pragmatic Play counts this 2023 release as the tenth title in its Big Bass franchise, and it packs in a lot: six reels of changing height, cascading wins, mystery symbols and two separate bonuses. One is a free spins round whose retriggers the studio says no longer have a limit. The other is a hold and spin round with a resetting counter. The catalogue lists a 96.7% RTP with no volatility or max win.
Six reels, 147,456 lines and a cascade
The board has six reels that change shape from spin to spin. The studio says players need a matching combination of rods, lures and other fishing equipment across 147,456 paylines to be awarded a win. In a Megaways layout, that is the count of possible ways to win at its peak.
Winning symbols are removed from play and new icons fall into the gaps, which can grant further wins within the same spin. This is a cascade system rather than a one-result-per-spin design.
Mystery symbols
Mystery symbols can also land on the board. They reveal a matched symbol, and the revealed symbol can help form wins. The studio does not say how often they appear or what they replace, so their impact is left as a feature to watch for rather than a number to count.
Two bonuses
The studio states that two bonuses are present. The first is the franchise's multiplier and retrigger free spins, here upgraded to give unlimited retriggers. The second is a hold and spin round.
Free spins with unlimited retriggers
This is the franchise's multiplier and retrigger free spins round. The change in this edition is that retriggers have no limit. The text we hold does not give the trigger count or the multiplier values, so those need to be read in the game.
Hold and spin
In this bonus, players are given three spins to land additional instant cash prizes. Each win resets the spins to three. The round therefore continues as long as prizes keep landing, and it ends once three spins pass without a new one.
What a session costs
At 96.7% the house edge is 3.3%, which is about $33 lost per $1,000 wagered over a long run. For 100 spins, the average cost is $0.66 at $0.20 a spin, $3.30 at $1 and $16.50 at $5, which is $500 wagered.
Volatility and max win are not published for this game. With an open-ended retrigger and a resetting hold and spin round, the length of a bonus can vary widely.
Games with the same return
Floating Dragon New Year Festival Ultra Megaways Hold and Spin (2023), Floating Dragon Megaways (2022) and Big Bass Bonanza Megaways (2021) list the same 96.7%. Wild Celebrity Bus Megaways is at 96.52%, 5 Frozen Charms Megaways at 96.5% and Sumo Supreme Megaways at 96.55%.
Pros
- Cascading wins on six reels of changing height
- Free spins retriggers are unlimited, according to the studio
- Hold and spin gives three spins that reset on each cash prize
- Free official demo available
Cons
- No volatility rating or max win in our catalogue
- The studio text gives no trigger counts or multiplier values
Verdict
Big Bass Hold and Spinner Megaways stacks cascades, mystery symbols and two bonuses on a 147,456-way board, with no cap on free spins retriggers and a hold and spin round that resets after every prize. The RTP is 96.7%, with a 3.3% house edge, and volatility is not published. Because the game has more moving parts than most, the free demo is a sensible place to learn them first.
