Are you ready to go fishing for wins? This Hacksaw Gaming slot is vivid, colorful, and the graphics are so clear that they almost seem 3D. Throw in a chilled-out, seafaring tune, and authentic sound effects like birds calling and waves lapping, and you'll feel like you're really on a boat.
From a visual perspective, this is definitely one of the best games we've seen recently. It's set on a big fishing boat, sailing on a clear blue sea. The graphics are crisp and bright, and animations make the whole boat seem to rock on the waves. The symbols are all colorful and eye-catching, with the main ones taking the form of tropical fish.
Marlin Masters The Big Hall is played on a standard 5x4 grid. The anchor Wild symbol pays out the most, but only if you get five of them. The next best symbols to get are the colorful fish, while the A, K, Q, J, and 10 symbols pay smaller amounts. To trigger a win, three of these symbols need to appear on one of the 14 paylines.
The special marlin symbols appear on the grid with cash values of up to 1,000x your stake. If the marlin symbol is part of the LootLine or is collected by a Fisherman, you'll be awarded the cash value displayed on the symbol. A LootLine is formed when there is a payline of marlin symbols on the grid.
When a Fisherman symbol appears, it collects the cash values of the marlin symbols and adds them to your win. The Fisherman can hold a Multiplier, which it applies to all of the marlin symbols. There's also an extra special Golden Fisherman symbol, which collects the marlin cash values and the Multipliers of all the other Fishermen on the grid.
You'll need to land three Scatter symbols to trigger the Don't Be Koi bonus game. You'll get eight Free Spins, and the bonus round comes with a Haul Bar, which increases every time a Fisherman lands. After every fourth Fisherman, you'll get an upgrade like extra Free Spins with a Multiplier.
There are also two more bonus rounds, which trigger if you get four or five Scatters. These bonus rounds have extra features like Sticky Fishermen and higher Multipliers.
The minimum bet on Marlin Masters The Big Haul is $/€/£0.10 per spin, and the maximum you can play for is $/€/£100. The volatility of this game is medium, so wins tend to be quite well spread, although the gameplay is less exciting than in high-volatility games. The Return to Player (RTP) percentage is 96.28%, which is above average.
If you're into great graphics and exciting bonus rounds, Marlin Masters The Big Haul is for you. The Fisherman symbols, LootLines, and Multipliers all offer a great way to boost your winnings. The maximum win of 10,000x your stake and the RTP of 96.28% are decent, but not anything out of the ordinary.
