The SixSixSix slot machine is a game developed by the renowned online casino software provider, NetEnt. This review aims to provide an in-depth analysis of the game’s theme, design, symbols, payouts, and various features that contribute to its overall gaming experience.

Theme and Design

As the name suggests, the SixSixSix slot has a sinister and mysterious theme centered around the number 666, often associated with the devil or evil. The SixSixSix game is set against a dark background with ominous music playing in the background, adding an eerie atmosphere. The graphics are of high quality, with detailed designs that bring out the supernatural elements. The symbols include a skull, a crossbones, and several card suits. These visuals combined create a spooky ambiance that complements the theme.

Symbols

The SixSixSix slot has five reels and ten paylines, offering a decent number of winning opportunities. The regular paying symbols in this game are represented by the A to 9 playing cards. In terms of payouts, these card values have relatively low value but can combine with other special symbols or bonus features to offer more substantial wins.

The higher-paying symbols include:

• A skull: This is a high-paying symbol that can reward players up to 50x their stake for landing five on an active payline.
• Crossbones: Landing this symbol, which serves as the game’s wild icon, on the reels grants rewards of up to 20 times the player’s bet.

The scatter and bonus symbols will be covered in more detail later. The symbols are not excessively rare, but with enough spins, one can reasonably expect a decent number of appearances from these higher-paying icons.

Payouts

While there is no fixed jackpot in SixSixSix slot, the game does feature an Auto Play function that allows players to set up a series of bets or choose various options. When playing on maximum stakes, hitting 5 skull symbols across all reels will award 50 times one’s bet amount – which represents the highest payout available.

Wilds and Scatters

In SixSixSix slot, the Crossbones icon acts as both wild and scatter symbol. This duality means it can contribute to winning combinations by substituting for missing regular-paying symbols, thereby completing a successful line or winning combination.

When the crossbones lands on reels 1, 2, 3, 4, and 5 simultaneously (horizontally across all five positions), they award two hundred times one’s total stake. Furthermore, it also triggers seven free spins that come with doubled rewards during this bonus round.

Bonus Features

Free Spins – Triggered by three or more Scatter symbols anywhere on the reels. The six scatters that initiated this feature will become sticky for its duration and guarantee wins each spin while locked into place – in addition to normal free-spins mechanics.

Another interesting aspect of SixSixSix slot is the "Scatter" symbol, which can activate 7 bonus spins. The unique twist here lies within ‘sticky’ reels (the first five scatter positions) that are held stationary until completion or any loss, providing multiple win chances per spin, thereby boosting overall potential payouts.

RTP and Volatility

While some online slots offer high RTPs exceeding the industry standard of 95%, SixSixSix is not among them. Its average return-to-player (RTP) rate hovers around 94.12%. As for volatility levels – which dictate how frequently or infrequently wins occur, this slot appears to be in line with many other modern NetEnt releases: a mid-level variance.

Betting Range and Max Win

Players can place their bets anywhere from $0.20 up to $100, making it suitable for both low-stakes players looking to stretch their bankrolls as well as those willing to make more substantial investments hoping to catch that big win.

The highest amount available in this game is 50 times your initial bet placed on maximum stakes; winning under such conditions would translate into a respectable payout of $5,000 – not bad for an average slot machine like SixSixSix.
