Big Bass Vegas Double Down Deluxe: playing it at Prince Casino

A Pragmatic Play video slot on a 5x3 grid with 10 fixed paylines, a high-volatility 96.50% RTP and free spins where fish money values are collected.

Redeem 18+ only. Full terms apply.
Big Bass Vegas Double Down Deluxe

You have read the name, here is the game

Money that waits for free spins. Ten fixed paylines run across five reels and three rows, and every win travels left to right from the leftmost reel. The look is a Las Vegas poolside fishing trip: speedboats, flamingos and gold tackle alongside the royals. Fish can land carrying a money value at any point, but that value stays on the reels until the free spins are running.

Is this built for your budget? High volatility suits players who accept long quiet stretches for the chance of a heavier payout, and £0.10 is a real starting stake here. Anyone wanting a steadier rhythm, or a bet above £5, will find this game tighter than expected. Fire up the reels at £0.20 and the money values remain decorative until the free spins arrive.

Collection beats tumbling here. Where many Pragmatic Play titles lean on tumbling reels, this one leans on collection: fish holding money values, a wild fisherman, and multipliers inside the free spins. A retrigger can extend the round, and two differently dressed fishermen feed separate on-screen meters, one blue at the top and one red at the bottom.

Round walk-through

From stake chosen to free spins triggered

Here is the whole shape of a round, from setting the stake to cashing in fish money.

No payline choices, just a stake
Ten fixed paylines mean every stake covers the board, so you choose only the amount. Stakes run from £0.10 to £5, and the paytable on screen updates to match whatever you pick.
Leftmost reel first, always
Symbols pay left to right on adjacent reels, starting from the leftmost one, and each line win is multiplied by your bet per line. A run that starts mid-board earns nothing.
Treat fish money as locked
Fish can land carrying random money values, but those values sit inert until free spins begin. Multipliers, scattered symbols and the wild fisherman fill the rest of the board without changing that rule.
The fish values start paying
Three or more scattered symbols open the bonus round, where the collected fish values finally pay out and extra triggers can extend the count. Nothing tells you how often that happens.
Decide your stop before the start
Deposit limits, loss limits and session time limits are set in your account before the reels move. Fixing a stopping point in advance keeps the trip recreational, whatever the fish do.

What do the reels do before free spins begin?

Follow the fish to the bonus. 5 reels x 3 rows, 10 fixed paylines; wins pay left to right on adjacent reels from the leftmost reel, multiplied by bet per line. Fish symbols can carry a random MONEY value on the reels but it is only collectible once Free Spins is active.

What can you count on in advance?

Your wait between features. 10 fixed paylines decide every win, but the moment a round of free spins begins stays closed to you. No pattern of spins brings it closer.

Will tonight match the average? 96.50% is a long-run average across thousands of spins, not a forecast for one evening. A short session can end well above or below it.

Same game, two settings. The same game can be published under different return settings. Only the rules screen inside the version you open shows which one is dealing your cards.

The cap on any single round. A 5,000x ceiling is a limit on one round, not a target. Reaching it takes a run of rare symbols landing together, which is why few sessions get near it.

What stays in your hands

Check what the UK market allows before you spin

18+Worth a glance once your stake is on screen, before you settle in for a session.
£5 → £25 000

Know your top win

The law caps a single spin at £5 here, so the top stake pays a maximum of £25,000; the game itself would allow more, the market does not.

Spin by spin, by hand

Autoplay is not offered on this market, so every spin is started by hand and you stay in charge of how long a session runs.

What the average means

See what one version gives back

The return is a long-run average over many spins, and a casino may run one of the versions listed; the player finds the version in the game rules.

Clarity up front

Big Bass Vegas Double Down Deluxe in plain answers

Every figure below comes from the game sheet Prince Casino publishes for this slot.

trustHow long can I try Big Bass Vegas Double Down Deluxe for free?+
No demo version of this slot is offered here; it runs on real balance only. Watching the reels turn on the base game costs nothing to learn, since a single spin at £0.20 shows you how wins and fish values work. Decide your budget first, then play.
trustDo I need a big stake to chase the Big Bass Vegas Double Down Deluxe max win?+
A full screen of the top symbol at the highest multiple pays 5,000 times your stake. On this market's £5 ceiling that is £25,000, and at £2 it is £10,000. Reaching it depends on the round, not on your choices.
trustWhy does Big Bass Vegas Double Down Deluxe show only one RTP figure?+
One published setting returns 96.50% over £100 staked, and no other version is listed for this slot. That figure describes a long run of spins, not your session. A short sitting can end up anywhere on either side of it.
trustWhat happens when I lower the stake on Big Bass Vegas Double Down Deluxe?+
Stakes run from £0.10 to £5, and the paylines are fixed at 10, so nothing changes but the amount. At £1 a line win pays ten times the table value; drop to £0.20 and every prize shrinks with your stake.
trustDo I need a large balance for Big Bass Vegas Double Down Deluxe volatility?+
This is a high-volatility game, so long quiet stretches are normal between paying rounds. Budget for that rhythm before you start rather than raising your stake to chase a win. The bonus timing is not something anyone knows in advance.

Big Bass Vegas Double Down Deluxe is a game, not a plan

Session budget. Fix a spend for the session at a level you would not miss, and treat it as the whole cost of the evening. Once that figure is gone, the reels stop being entertainment and start being a bill.

Big Bass Vegas Double Down Deluxe stopping rule. Name the point where you walk away before the first spin, and include the point after a big fish lands. A win is the easiest moment to keep going past what you planned.

Account limits, set once. Deposit and loss limits in your account cap what can leave your balance, whatever the reels are doing. Set them at a level that fits your month, then leave them alone during play.

Fun first, spins second. Thirty-five spins at £1 told you whether you are still enjoying it; if the answer is no, close the game and come back another day. Longer breaks and full self-exclusion are available whenever you need them.
