Gambling involves risk. Play responsibly and within your budget. 18+
Blast the Bass is a new slot from Belatra Games released on 20 February 2025. Blast the Bass swaps fishing rods for dynamite and turns an underwater scene into a collection mechanic. We tested this slot across demo and real money sessions for this Blast the Bass review. The grid runs 5 reels by 4 rows with 20 fixed paylines. As a high RTP slot, Blast the Bass sits at 96.72% with high volatility and a 5,000x max win.

Blast the Bass Overview
Belatra built Blast the Bass around a single idea: the Fisherman Wild collects fish values across the screen. This separates Blast the Bass from passive fishing slots where the player waits for free spins. The base game stays active because every wild landing can pay regardless of bonus mode. Bet range covers £0.20 to £250, which fits casual play and high-stake real money slot sessions. Blast the Bass runs in-browser on desktop and mobile, with no download or dedicated app required. We loaded it instantly on iOS Safari and Android Chrome at the same speed.

How to Start Playing Blast the Bass
Blast the Bass is available at UK-licensed casinos in two formats. The demo runs without registration. Real money play requires a verified account at a Gambling Commission–licensed operator. Both formats load in-browser — no app download, no installer.
Play Blast the Bass Demo for Free
The Blast the Bass demo runs the full game with virtual credits. No registration, no deposit, no app download needed. Demo play covers every Blast the Bass feature including the Buy Bonus options and the booster panel. Access takes four steps.
- Open the Blast the Bass game tile on a review site or Belatra’s free-slot portal.
- Click “Demo” or “Free Play” — no account required.
- The game loads with a virtual balance, usually 1,000–5,000 credits.
- Adjust bet size and spin as normal.
We recommend 200–300 demo spins before any real money attempt. The reason is volatility: dry spells last long enough to misread Blast the Bass from a short trial.

Real Money Testing — Six-Day Log

We funded a UK account and ran Blast the Bass for six consecutive days. Sessions stayed inside a £200 bankroll cap with the Bet +25% toggle off. The Blast the Bass test table records each day end-to-end: bet size, spins, biggest win, features triggered, and net result.
| Day | Date | Bet | Spins | Biggest Win | Features Hit | Net Result |
|---|---|---|---|---|---|---|
| 1 | 02.06.2026 | £0.50 | 240 | £14.50 (29x) | Fish Rain x1 | −£42 |
| 2 | 03.06.2026 | £1.00 | 180 | £62.00 (62x) | Free Games (3 scatters) | +£18 |
| 3 | 04.06.2026 | £0.40 | 300 | £88.40 (221x) | Fish Rain x2, Free Games | +£54 |
| 4 | 05.06.2026 | £0.80 | 150 | £24.00 (30x) | Buy Bonus (Fish Rain, 20x) | −£71 |
| 5 | 06.06.2026 | £1.00 | 200 | £412.00 (412x) | Hot Mode (5 scatters), boosters 1–3 | +£268 |
| 6 | 07.06.2026 | £0.50 | 220 | £19.50 (39x) | Fish Rain x1 | −£35 |
Six days closed at +£192 net across 1,290 spins. The single Hot Mode session on day five carried the bankroll. Outside that trigger we ran a slight loss, which matches a 1:100.36 feature frequency. Blast the Bass rewards session length, not aggressive bet escalation.
Winning Statistics
Blast the Bass payout data comes from a tracked casino network covering UK operators. The figures cover daily winning spins, total daily payouts, top multipliers, and largest single-session wins. Reading these charts alongside our six-day log gives a fuller picture than either alone.
Number of Winning Spins Per Day
Blast the Bass winning spin counts stay within a tight band across tracked UK casinos. Spikes correlate with weekend traffic rather than payout density. The chart confirms volatility is structural, not market-dependent.
Total Amount of Winnings Per Day
Blast the Bass daily payout totals swing harder than winning spin counts. One large multiplier hit can lift a daily total by an order of magnitude. This pattern repeats across high payout slot data.
Biggest Multipliers
Blast the Bass top multiplier hits across tracked UK casinos in the last 14 days.
| Multiplier | Win | Bet | Casino | Date |

| x1,419 | £283.73 | £0.20 | Legion Bet | 11.06.2026 |
The x3,427 hit on 5 June sits below the 5,000x theoretical cap on Blast the Bass. No tracked session reached maximum in this window.
Big Wins
Blast the Bass largest single-session wins recorded across tracked UK casinos.
| Win | Bet | Multiplier | Casino | Date |
|---|---|---|---|---|
| £94,440 | £62.50 | x1,511 | OnLuck | 08.06.2026 |
| £36,830 | £62.50 | x589 | OnLuck | 07.06.2026 |

| £12,020 | £200 | x60 | Legion Bet | 02.06.2026 |
| £10,800 | £200 | x54 | Lucky Wave | 30.05.2026 |

| £8,750 | £50 | x175 | Lucky Wave | 03.06.2026 |
| £6,580 | £20 | x329 | Lucky Wave | 11.06.2026 |
Mid-stake hits between £25 and £62.50 appear more often than micro-bet jackpots, which suggests bet sizing matters for the highest Blast the Bass payouts.
Symbol Values and Paytable
Blast the Bass uses a tiered paytable led by the purple octopus, with card royals at the bottom. Special symbols — Fisherman Wild, TNT Scatter, Fish Symbols, Fish Coins — drive the real value. The table shows base payouts as multipliers of bet line.
| Symbol | 5 of a kind | 4 of a kind | 3 of a kind |
|---|---|---|---|
| Purple Octopus | x100 | x25 | x10 |
| Orange Crab | x50 | x15 | x5 |
| Fishing Rod | x10 | x4 | x2 |
| Fish Bucket | x5 | x2 | x1 |
| Hook | x4 | x1.5 | x0.75 |
| School of Fish | x3 | x1 | x0.5 |
| Ace | x2 | x0.75 | x0.4 |
| King | x1.75 | x0.7 | x0.35 |
| Queen | x1.5 | x0.6 | x0.3 |
| Jack | x1.25 | x0.4 | x0.2 |
| TNT Scatter | Triggers Free Games | — | — |
| Fisherman Wild | Substitutes + collects | — | — |
Bonus Features

Blast the Bass layers seven feature mechanics that interact rather than run in isolation. Each one feeds the next. The Fisherman Wild drives every collection. Fish Symbols and Fish Coins sit on the reels and wait. The booster panel turns Free Games into a campaign instead of a 10-spin sprint. Bonus Buy and Bet +25% give the player real choices before the spin button.
Fisherman Wild Symbol
Blast the Bass Fisherman Wild lands on all five reels and substitutes for paying symbols. Its real job is collection. Every wild on screen sums all Fish Symbol values and pays the combined total. Multiple wilds collect in parallel rather than competing. The same logic applies to Fish Coins. A single wild landing during a heavy reel can settle a five-figure swing. This is the single mechanic that defines Blast the Bass.
Fish Rain Mechanic

Blast the Bass Fish Rain fires randomly when a wild lands, or you can buy it directly. The fisherman throws dynamite, the screen shakes, and Fish Symbols rain across the reels. Each new symbol carries a random multiplier between x2 and x1,000. The wild on screen collects every value at once. Fish Rain runs in both base game and Free Games. We hit it three times across our six-day log — once paying 221x on day three.
Fish-Coin Feature
Blast the Bass Fish Coins behave differently across game modes. Base game coins drop straight to the bottom row with value rising by distance travelled. Free Games coins move one step per spin and persist until collected. The Blast the Bass base game value scale runs from x10 at landing to x100 at the bottom row.
| Distance Travelled | Value |
|---|---|
| Starting position | x10 |
| 1 position | x20 |
| 2 positions | x50 |
| 3 positions (bottom) | x100 |
Without a wild on screen, the coin disappears at the bottom row. This creates a slow-burn tension where high-value coins descend while you wait for a wild.
Free Spins System

Blast the Bass Free Games trigger from three or more TNT Scatters. The setting shifts to stormy sea with sharks circling the reels. All wilds that land lock to a panel above the grid for the rest of the round.
| Scatters | Free Games | Extra Booster |
|---|---|---|
| 3 | 10 | None |
| 4 | 10 + 10 extra | x2 multiplier on extra 10 |
| 5 | 10 + 10 extra | x3 multiplier on extra 10 (Hot Mode) |
The sequence caps at 45 Free Games total.
Booster Panel Mechanism
Blast the Bass booster panel splits into two phases. Phase one rewards wild accumulation in blocks of four. Phase two escalates multipliers with one wild per step.
| Booster | Wilds Required | Reward |
|---|---|---|
| 1 | 4 | 10 spins x2 |
| 2 | 8 | 10 spins x3 |
| 3 | 12 | 10 spins x10 |
| 4 | 16 | x20 multiplier (no spins) |
| 5 | 17 | x30 multiplier |
| 6 | 18 | x40 multiplier |
| 7 | 19 | x50 multiplier |
| 8 | 20 | x100 multiplier |
Early stages stretch the round. Late stages explode the multiplier.
Bonus Buy Options

Blast the Bass Buy Bonus offers four fixed-cost entries. Availability varies by UK casino under licence rules — check the game info panel before deposit.
| Option | Cost | Detail |
|---|---|---|
| Fish Rain | 20x bet | Triggers dynamite mechanic with random wilds and Fish Symbols |
| Fish Coins | 50x bet | Guarantees wilds with x100 Fish Coins |
| Standard Free Games | 100x bet | 10 Free Games with full booster panel |
| Hot Mode | 400x bet | Replicates a 5-scatter trigger with two pre-activated boosters |
Our 20x Fish Rain buy on day four returned 8x — one trial, not a pattern.
Bet +25% Feature
Blast the Bass Bet +25% toggle increases each spin cost by a quarter and boosts Free Games trigger frequency. A £1 base spin becomes £1.25. Winnings still calculate against the £1 base, not the inflated stake. The trade is faster bonus access for higher cost per spin. We left this toggle off during the six-day log to keep results comparable across days. Players chasing Hot Mode triggers in shorter sessions get the most from this option.
Similar Slots
Blast the Bass competes with three established fishing slots and one Belatra stablemate. The comparison table covers RTP, max win, provider, and release year.
| Slot | Provider | RTP | Max Win | Released |
|---|---|---|---|---|
| Big Bass Bonanza | Pragmatic Play | 96.71% | 2,100x | 2020 |
| Fishin’ Frenzy Megaways | Blueprint Gaming | 96.10% | 10,000x | 2019 |
| Big Bass Splash | Pragmatic Play | 96.71% | 5,000x | 2022 |
| Mummyland Treasures | Belatra | 96.50% | 6,000x | 2022 |
Blast the Bass distinguishes itself through the dual collection system — Fish Symbols and Fish Coins working together — rather than a single bonus loop.
Final Thoughts
Blast the Bass earns attention on mechanics rather than novelty. The Fisherman Wild collection system keeps the base game live, not idle. The booster panel turns Free Games into eight-stage progression. Our six-day real money log closed at +£192 across 1,290 spins, with the result resting on one Hot Mode trigger. Blast the Bass is a high payout slot built for patient sessions, not short bursts. Suited to high-volatility veterans, fishing-slot fans wanting fresh mechanics, and players who read maths before brand. Not suited to small bankrolls or anyone needing frequent small wins to stay engaged.
Responsible Gambling
Blast the Bass is a high-volatility slot. Long dry spells between wins are part of the maths, not a fault. Set a deposit limit, a loss limit, and a session time limit before you spin.
