There are 6 bonus features to enjoy as part of the Marlin Masters slot game, which are Lootlines, Catch Them All!, Reel It In!, Off The Hook!, Plenty of Fish in the Sea and a Bonus Buy.
Lootlines
Marlin symbols bring payouts, and each symbol has a cash prize of one of the following amounts: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, 250x, 500x or 1,000x. Marlin symbols are collected when there are 3 or more matching symbols that are part of a win.

Catch Them All!
The fisherman reels in big wins if at least 1 symbol lands at the same tie as the marlin symbol. He acts as a collector, collecting all marlin cash prizes on the grid, with multipliers up to 20x. Multiple fishermen landing on the grid work together for bigger payouts.
Reel It In!
Landing 3 FS symbols triggers the Reel It In! free spins bonus feature, where you receive 10 free spins. During the feature, the Marlin Progress Bar appears on top of the grid. Whenever a fisherman symbol lands on the grid, the Marlin Progress Bar advances by one step. This happens whether or not the fisherman collects any marlin symbols during that round. As the bar progresses, your rewards grow with each new level reached:
- Upgrade 1: After collecting 4 fisherman symbols, you'll earn 10 additional free spins, with all subsequent fisherman symbols guaranteed to have a multiplier value of at least x2.
- Upgrade 2: At the next stage, another 10 free spins are awarded, and all fisherman symbols gain a minimum multiplier value of x4.
- Upgrade 3: Reach the top level to gain 10 more free spins, ensuring all fisherman symbols land with a multiplier value of at least x10.
Off The Hook!
Landing 4 FS symbols triggers the Off The Hook! feature, where there are 15 free spins. The Marlin Progress Bar also appears here but with better upgrades, which you can see below. All fisherman symbols come with a guaranteed multiplier of at least x2, and you progress through the levels by collecting fisherman symbols to unlock the following upgrades:
- Upgrade 1: Collect 4 fisherman symbols to earn 15 additional free spins, with all subsequent fisherman symbols carrying a multiplier value of at least x4.
- Upgrade 2: Reach the next level to gain another 15 free spins and boost all fisherman symbols with a minimum multiplier of x10.
- Upgrade 3: Hit the top stage to receive 15 more free spins, ensuring every fisherman symbol lands with a multiplier of at least x15.

Plenty of Fish in the Sea
Landing 5 FS symbols triggers the Plenty of Fish in the Sea feature, where there are 10 free spins. Every marlin symbol that lands carries a minimum multiplier value of 5x. And on every spin during this feature, at least 1 marlin symbol and 1 fisherman symbol will land, significantly increasing your chances to collect big payouts.
