Octo’s Sunken Haul Slot Features

Sunken Chest, Free Spins, Super Free Spins, Ink, Tentacles, Octopus Collector and The Porthole give Octo’s Sunken Haul its layered online slot gameplay, combining sticky crates, collection values, multipliers and bonus buys.

Ink

When the reels stop, every Ink splash on the screen turns into the same symbol. That symbol can be a paying symbol, a Wild or a Crate, and each crate keeps its own value. The game then counts wins after the reveal, which can improve line hits and crate totals.

Tentacles

In the base game, if 4 or 5 crates land and no bonus starts, the octopus may reach out and grab every crate. Their values are then added to the win. This gives ordinary spins an extra collection layer without needing a separate feature trigger.

Octopus Collector

In Free Spins, the Octopus can land on the reels and collect the value of every crate on the screen. The game multiplies those crate values by the porthole multiplier, then lights one arm of the porthole. That makes each landing part of a clear progression system.

The Porthole

The Porthole has 8 arms. Each level raises the collect multiplier and adds +5 Free Spins. The levels are x2 at 2 arms, x3 at 4 arms, x5 at 6 arms and x10 at 8 arms. At 8 arms, Grand Haul starts and every crate stays on the reels.

Free Spins

3 anchors start 10 Free Spins, 4 anchors start 12 Free Spins, and 5 anchors start 15 Free Spins. Anchors anywhere on the screen trigger the feature. During this mode, Octopus Collectors grab crates and advance The Porthole, while 3+ anchors add +5 more spins.

Super Free Spins

Super Free Spins start with 4 arms already lit, so the round begins at x3. These starting arms do not add spins, but they give the feature an immediate head start. The mode still plays as a 10 to 15 spin bonus with the same collection structure.

Sunken Chest

6 or more crates in the base game open the Sunken Chest. The crates stay in place and you get 3 respins. Every new item that lands sticks and resets the respins to 3. The chest ends when no respins are left or when it is full, then everything inside adds to the win.

• Crate: its value.
• Sucker: doubles the crates next to it.
• Octopus: copies the total of all crates as its own value.
• Arm: one more row, up to 6 rows.

Bonus Buy

The menu holds one armed mode, Double Chance, and three direct buys.

• Double Chance: x1.25 the bet per spin; Anchors and crates land more often, so Free Spins and the Sunken Chest trigger more frequently.
• Sunken Chest: x40 the bet; opens the chest directly.
• Free Spins: x100 the bet; starts 10 to 15 Free Spins.
• Super Free Spins: x160 the bet; starts with 4 arms lit.

Octo’s Sunken Haul Slot Review

Octo’s Sunken Haul builds its identity around a sunken pirate setting, with teal ocean tones, brass framing and a clear octopus motif across the reels and bonus screens. The theme works because the art supports the chest, anchors and crate system instead of sitting on top of it.

The Hold & Win structure gives the slot its main edge, especially because crates can stick, respins reset on new landings, and Free Spins add The Porthole progression. High volatility and a 15,000x cap keep the game focused on swings rather than steady base play, which makes the buy menu feel relevant.

Octo’s Sunken Haul combines 20 fixed lines with Sunken Chest, Free Spins and Super Free Spins, while its 96.50% RTP applies in every mode.
