The Big Bass Vegas 1000 slot is a Las Vegas-themed entry in Pragmatic Play's Big Bass fishing series: 5 reels, 3 rows, 10 paylines, a published RTP of 96.53%, medium volatility and a top prize of 15,000 times your stake. Like the rest of the series, it saves its biggest moments for free spins where a fisherman collects fish cash values. Here is how that works and what it costs.
Published RTP is 96.53%: an average long-run cost of £3.47 per £100 staked.
Rated medium volatility, unlike the high-volatility original Big Bass Bonanza.
Max win is 15,000× stake: £30,000 at £2 and £75,000 at £5.
PlayOJO's 80 no-wagering spins are on Big Bass Bonanza, not this game; check each lobby for availability.

Where the Big Bass Vegas 1000 slot fits in the series
The Big Bass series began with Big Bass Bonanza, released on 14 December 2020 by Reel Kingdom and distributed by Pragmatic Play. It became one of the best-known fishing slot machines, and dozens of themed spin-offs followed, from Christmas and Halloween editions to Vegas-styled versions. Big Bass Vegas 1000 belongs to the higher-ceiling branch marked by the 1000 label.

The comparison shows what is unusual about this edition. The ceiling is far higher than the original's, yet our checked data rates volatility as medium rather than high. Volatility ratings come from different sources and methods, so treat them as a guide, not a measurement. For the Vegas branch's other title, see Big Bass Vegas Double Down Deluxe, and for its higher-ceiling sibling, Big Bass Bonanza 1000.
How the Big Bass Vegas 1000 slot machine pays in the base game
The base game is a straightforward 10-line slot. Themed picture symbols make up the higher-paying tier and card values fill the lower one; the help screen shows each symbol. Lines pay from the leftmost reel, and the paytable lists each symbol's value at your stake.
Set the total stake; with 10 lines, a £1 stake means 10p per line.
Press spin. The random number generator picks the stop positions, and the result is fixed.
The reels animate for at least 2.5 seconds, the UK minimum.
Each of the 10 lines is checked for three or more matching symbols from reel 1.
Fish money symbols may land showing cash values; in the series' standard design they pay only when a fisherman collects them in free spins.
Scatters are counted; enough of them start the free spins, otherwise the next spin can begin.
Fish money symbols landing in the base game without a collector is a common source of frustration, but they are simply part of the reel strip. They carry no message about what comes next.
Big Bass Vegas 1000 free spins and fish collection
Landing the required scatter symbols starts the free spins. In the series' core design, the fisherman appears as a wild during this round, and every fisherman that lands collects the cash value of every fish money symbol on screen. Collecting a set number of fishermen typically retriggers more spins and raises a multiplier on later collections. The Vegas 1000 help screen sets out this edition's exact trigger counts, retrigger steps and any extra modifiers, and those details decide how the round behaves.
A worked collection example
Say you play at £1 and, during free spins, three fish land showing £2, £5 and £10, alongside one fisherman. The fisherman collects £17. Later, after a retrigger raises the multiplier to 2× (illustrative), a fisherman lands with two fish worth £3 and £20. That collection is worth £23 × 2 = £46. The fish values and multiplier steps are for illustration: the actual ranges are listed in the game. This collector idea is covered in our page on cash collect.
Pragmatic Play does not publish how often the free spins trigger. Figures quoted on forums are personal tallies, not official data.
Big Bass Vegas 1000 RTP and cost per 100 spins
The published RTP is 96.53%, so over millions of spins the game returns £96.53 per £100 staked on average and keeps £3.47. Pragmatic Play supplies many games at more than one RTP setting, so confirm the figure in the game's information pages. The table shows what that average means at common stakes.

UK rules on the Big Bass Vegas 1000 slot
UK versions have had no autoplay, no turbo or slam-stop and a minimum spin of 2.5 seconds since 31 October 2021, and wins at or below the stake are not celebrated. Bonus buy is not offered on slots supplied to Great Britain, so free spins come only from scatters.

Frequently asked questions
What is the Big Bass Vegas 1000 RTP?
Big Bass Vegas 1000 has a published RTP of 96.53%, which means the game returns £96.53 for every £100 staked on average over millions of spins. The house edge is 3.47%. Pragmatic Play supplies many games at more than one setting, so the figure printed in your casino's game rules is the one that applies to you. Our guide to finding a slot's RTP shows where to look, and are high RTP slots better? explains what the number means.
What is the Big Bass Vegas 1000 max win?
The maximum prize on Big Bass Vegas 1000 is 15,000 times the stake. At £1 per spin that is £15,000; at the £2 limit for players aged 18 to 24 it is £30,000; at the £5 limit for players aged 25 and over it is £75,000. This is a ceiling built into the maths, and very few rounds come close. When a round reaches the cap it ends early. Read our explainer on max win caps and what slot has the biggest max win?.
How do the Big Bass Vegas 1000 free spins work?
The free spins start when enough scatter symbols land. In the Big Bass format, a fisherman wild appears during the round and collects the cash values of every fish money symbol on screen, and collecting a set number of fishermen usually retriggers spins and raises a multiplier. This edition's exact counts and modifiers are in the help screen. There is no bonus buy at UK casinos. See how free spins work and the fisherman symbol.
Is Big Bass Vegas 1000 high or medium volatility?
Our checked data rates Big Bass Vegas 1000 as medium volatility, which is lower than the high rating given to the original Big Bass Bonanza and Big Bass Bonanza 1000. Volatility ratings are estimates published by developers and review sites, so treat them as a rough guide to how much results swing. Expect quiet spells in the base game with the larger results concentrated in free spins. Our volatility explainer and high vs low volatility slots comparison go further.
Can I use PlayOJO's free spins on Big Bass Vegas 1000?
No. PlayOJO's welcome offer gives 80 free spins on Big Bass Bonanza, the original game in the series, not on Big Bass Vegas 1000. The offer is for new UK customers aged 18+, excluding Northern Ireland, after a first deposit of at least £10, with spins worth 10p each and winnings paid in cash with no wagering. Terms apply and it can't be combined with other offers. See our PlayOJO page and 80 free spins explained for details.
Who makes Big Bass Vegas 1000?
Big Bass Vegas 1000 is supplied by Pragmatic Play, which distributes the Big Bass series. The series began with Big Bass Bonanza, created by Reel Kingdom and released on 14 December 2020, and grew into a large family of themed editions. Pragmatic Play is headquartered in Gibraltar and is licensed by the Gambling Commission among more than 30 regulators. Our profiles of Pragmatic Play and Reel Kingdom explain how the two studios work together.
Can I play the Big Bass Vegas 1000 demo?
You can play a Big Bass Vegas 1000 demo with virtual credits at many UK-licensed casinos, but only once your age has been verified, as required in Great Britain since May 2019. The demo shows the same free spins, fisherman collections and paytable, so it is a cost-free way to learn the rules. It cannot tell you when a real-money bonus will land. Read our demo slots guide and the page on demo slot age verification.
How much do 100 spins on Big Bass Vegas 1000 cost?
One hundred spins put 100 times your stake through the game, and the average cost is 3.47% of that over the long run. At 10p per spin, £10 is staked with an average cost of about 35p; at £1, £100 is staked with an average cost of £3.47. Real sessions vary a lot, especially when free spins land or don't. Try the slot cost calculator and read what is a session budget for slots?.
Why do fish symbols not pay in the base game?
In the Big Bass format, fish money symbols show cash values but are normally paid only when a fisherman wild collects them, and the fisherman generally appears during free spins. So fish landing in the base game usually pay nothing on their own. They are part of the reel strip and do not mean a bonus is coming, because each spin is independent. Check this edition's help screen for any base-game exceptions. Our page on cash collect features explains the idea.
Is Big Bass Vegas 1000 fair?
Yes, at UK-licensed casinos Big Bass Vegas 1000 uses a tested random number generator and maths that must meet Gambling Commission standards, so spins are random and not adjusted to the player. Fair means the published odds are real, not that you are likely to come out ahead; the game keeps an average of 3.47% of stakes over time. See are slot machines rigged? and how slot machines decide who wins.
