Deep Six by Quickstrike Slot Overview
Deep Six by Quickstrike explores a richly coloured underwater shipwreck, framed by coral and barnacled timber. It shares Wild multipliers with Dragonspire, but here a brass-suited diver represents Wilds that sink down the reels, growing stronger as they descend.
Sinking Wild multipliers reach x10, while Salvage removes winning low symbols throughout the bonus. These connected features give this high-volatility slot its distinctive progression, with a maximum win of 25,000x the bet. Explore the depths with the free demo on BonusTiime, without an account or deposit.

Deep Six Slot Specifications
Deep Six uses a 5×4 grid and 1,024 ways to win. It keeps the action compact, while the bonus systems add extra movement and symbol removal to the Quickstrike slot.
RTP (Return to Player)
RTP is 96.00%, with a 4.00% house edge. That gives Deep Six a standard return profile for online slot gameplay.
Volatility
High volatility means the game can swing sharply, so stake management matters during extended sessions.
Max Win
Max win is 25,000x the bet, so a €1 spin caps at €25,000.
Deep Six Slot Features

Sinking Wild, Salvage, Free Spins, and the buy options all shape Deep Six with sinking multipliers, symbol removal, and direct bonus entry paths that change how each round develops.
Sinking Wild
The Sinking Wild lands on a reel and drops one row each respin in its own column. It substitutes for every symbol except Scatter, and it carries the multiplier of the row it sits on, from x1 at the top to x10 at the seabed.
- Row 1 (top): x1
- Row 2: x2
- Row 3: x5
- Row 4 (seabed): x10
When more than one Wild affects the same way, their multipliers add together. In bonus rounds, respins do not use a free spin, and Scatters do not land on respins.
Salvage
Salvage works inside the bonus games. The first time a low symbol wins, the game removes it from the reels for the rest of that bonus. That improves the symbol mix and gives premium symbols more room to land.
Free Spins
Three Scatters trigger 10 free spins. During the bonus, low symbols that win disappear permanently from the round, so the reel set tightens as play continues. Sinking Wilds land more often than in the base game, usually high on the reels, and the bonus cannot retrigger.
Super Free Spins
Four Scatters trigger Super Free Spins. This version starts with the Cargo Crate and Shell Cluster already removed, which changes the symbol pool before the round begins. It also includes more Sinking Wilds, so the descent mechanic appears more often during the feature.
Hidden Treasure
Five Scatters trigger Hidden Treasure. This is the most advanced bonus, with every low symbol already removed and the most Sinking Wilds in play, and it always pays at least 250 times the bet.
Bonus Buy
The bonus button opens the menu. Ante Bet, Dive Spin and Deep Dive are switched on and charged on every spin until you turn them off, while Bonus, Super Bonus and Random Bonus are bought once and play right away.
- Ante Bet: x2 the bet per spin; greatly increases the Free Spins trigger rate, and wins stay on the base bet.
- Dive Spin: x50 the bet per spin; a Sinking Wild lands on the top row every spin and falls the whole way, and extra Wilds join the descent more often.
- Deep Dive: x500 the bet per spin; one spin with every low symbol removed, and 1 to 4 Sinking Wilds land and fall together.
- Bonus: x100 the bet; starts Free Spins.
- Super Bonus: x250 the bet; starts Super Free Spins.
- Random Bonus: x250 the bet; starts Free Spins 50% of the time, Super Free Spins 40% and Hidden Treasure 10%, and it is the only direct route to Hidden Treasure.

Deep Six Slot Review
Deep Six builds its identity around a submerged wreck, a brass diver, and a dark blue-green palette that keeps the presentation focused on the setting rather than decoration. The Sinking Wild concept suits that underwater layout, while the shipwreck framing and treasure symbols give the slot a clear, readable style.
The best part is the moving wild system, because Wilds sink, grow from x1 to x10, and can stack with other Wilds on the same way. That gives the base game more shape than a standard 1,024 ways setup. High volatility keeps the pressure on, though, and the buy menu adds options without hiding the risk.
Deep Six combines symbol removal during the bonus with a 25,000x ceiling. The design works hardest when the game starts stripping low symbols away, which gives the bonus real identity.
Deep Six Slot FAQ
How Do Free Spins Trigger In Deep Six?
Three Scatters trigger Free Spins, and the bonus starts with 10 free spins. Four Scatters trigger Super Free Spins, also 10 free spins, with the Cargo Crate and Shell Cluster already removed. Five Scatters trigger Hidden Treasure, which gives 10 free spins, removes every low symbol and always pays at least 250 times the bet.
What Does The Bonus Buy Menu Offer?
Deep Six offers six paid modes. Ante Bet costs x2 the bet per spin and raises the Free Spins trigger rate, Dive Spin costs x50 the bet per spin and Deep Dive costs x500 the bet per spin: all three stay on until you switch them off. Bonus costs x100 the bet, Super Bonus costs x250 the bet and Random Bonus costs x250 the bet, and those three are bought once.
What Is The Maximum Win In Deep Six?
The maximum win is 25,000x the bet. The rules also say the round ends as soon as the total reaches that cap, even if respins or free spins remain. That applies in every mode, including Dive Spin and Deep Dive, so the ceiling stays consistent.
Can You Play Deep Six For Free On BonusTiime?
Yes, Deep Six is playable for free on this BonusTiime page. You do not need a deposit or an account to try the demo. That makes it easy to test the rules, including the ways system, Sinking Wilds, and bonus triggers, before using real money anywhere else.
How Does The Sinking Wild Mechanic Work?
The Sinking Wild substitutes for every symbol except Scatter. It lands on the top row in Dive Spin, then drops one row on each respin. Its multiplier follows its row, from x1 at the top to x10 on the seabed, and multiple Wilds add together on the same way.
