Like all Lightning Box Games slots, the slot has a well crafted visual style and the theme is well realised, and this is backed up with suitable sound effects (even if the music is a little disappointing). The game has a wide range of coin sizes and so it’s accessible to all, and there are good-sized payouts on offer both during base play and in the free spins bonus round.

Extreme Fishing has proven to be an exceptionally popular slot since its release in August 2020, and you can check it out for yourself at one of our recommended UK online slot sites.

How to Play

Extreme Fishing is a 5 reel, 3 row video slot where all 25 paylines are automatically in play on every spin. Wins pay left to right (except for scatter wins which pay anywhere on the reels) and are multiples of the line bet (scatter wins are multiples of the total bet). Coins range in size from £0.01 to £5, so the minimum bet is £0.25, with a maximum wager of £125 per spin.

  • Shark symbol is wild and substitutes for all other symbols except the scatter
  • Hitting 5x wild symbols = 1,500x line bet (up to £7,500)
  • Hitting 4x wild symbols = 500x line bet (up to £2,500)
  • Bonus symbol is the scatter
  • Hitting 3x, 4 x or 5x scatter symbols anywhere on the reels triggers the free spins bonus round
  • Hitting 5x scatter symbols = 500x total bet (up to £62,500)
  • Hitting 5x fisherman symbols = 500x line bet (up to £2,500)
  • Hitting 5x trout symbols = 250x line bet (up to £1,250)
  • Hitting 5x grouper fish symbols = 250x line bet (up to £1,250)
  • Hitting 5x angel fish symbols = 150x line bet (up to £750)
  • Hitting 5x starfish symbols = 100x line bet (up to £500)
  • Hitting 5x crab symbols = 100x line bet (up to £500)


The maximum jackpot win on Extreme Fishing is 500x total bet, which is worth £62,500 when betting the maximum coin size.

Extreme Fishing is a high volatility slot game with a 95.84% RTP.

Special features

Free Spins Bonus Round

Hitting 3x, 4 x or 5x scatter symbols anywhere on the reels triggers the free spins bonus round, with the number of free spins awarded depending on how many symbols activate the feature:

  • 3x scatter symbols = 10 free spins
  • 4x scatter symbols = 20 free spins
  • 5x scatter symbols = 30 free spins

During the free spins bonus round, hitting 5x green swordfish symbols triggers the Fishing Feature. Played on a separate screen, during this game-within-the-game you have 15 chances to catch fish on a single reel on the right of the screen. Each fish symbol that you land moves the arrow on a dial (which is in the shape of a fishing rod reel) on the left of the screen up one spot, and adds the cash prize to the total fish value (between 1x and 25x total bet). Every red broken line symbol that you hit moves the arrow down the dial one spot.

The Fishing feature comes to an end when the arrow points to either the highest or lowest position on the dial, or when your 15 chances to catch fish have been used up. The final prize that you are awarded is shown above the single reel on the right and is added to your other wins during the free spins bonus round.

Further free spins can be triggered during the free spins bonus round.

Shark Attack Feature

The Shark Attack Feature can be randomly activated at any time, and all fish symbols become retrospectively wild shark symbols for 1 spin, creating the potential for more winning combinations.

Graphics and Sounds

Like all Lightning Box Games slots, the artwork on Extreme Fishing is excellent, with the fish symbols in particular beautifully crafted. The reels are set against a placid ocean background and are flanked by fishing nets. Three great white sharks swim threateningly across the reels and eat up any other fish symbols whenever the Shark Attack Feature is activated.

Throughout the game, there are background ocean sounds that create a gentle, peaceful atmosphere, although the serenity is somewhat shattered whenever a bonus symbol lands on the reels and there is a loud blast of music. To add to the effect, the sound of the spinning reels is designed to replicate the reel on a fishing rod being wound in.

The one disappointing feature of the game’s design is the banjo music that plays throughout, which is oddly slow and low key and does somewhat detract from the overall feel of the game.


Extreme Fishing is an excellent example of the sort of slots that Lightning Box Games produce. The overall gameplay is fairly straightforward, but the Fishing Feature game-within-the-game during the free spins bonus round is an innovative feature that adds an additional element that lifts it beyond being yet another run of the mill slot game.

The visual design is well crafted and the game looks good, although it is perhaps not up to the standard of other Lightning Box Games slots when it comes to the music and sound effects, which are quite dull and not really in keeping with the rest of the game.

Extreme Fishing is a high volatility slot that experienced slot players will enjoy and which we have played regularly since its release in 2020. You can try it out for yourself at WhichBingo’s list of best casino sites.
