Hacksaw Gaming has added a new entry to its growing catalogue of dark-themed online slots with the release of Pray for Six, a title that continues ideas first seen in earlier games such as Pray for Three and SixSixSix. The new game blends familiar mechanical elements with a fresh structure, while keeping the studio’s established visual style rooted in monochrome imagery and stylized depictions of the occult.

The online slot introduces players to a cartoon-styled infernal setting overseen by two characters positioned beside the reels: the Devil’s Spawn and Pyropup. One description likens them to “two hellraisers who leave a trail of tears behind them as they run wild across the infernal realm.” The overall presentation leans heavily on greyscale tones, punctuated by occasional flashes of color tied to feature symbols and prize wheels, continuing a visual approach Hacksaw Gaming has adopted across several recent releases.

Core Game Structure and Symbol Setup

Pray for Six runs on a six-reel, five-row grid and uses a scatter-pays system rather than fixed paylines. Wins occur when eight or more matching symbols appear anywhere on the matrix. Once a win forms, the contributing symbols disappear and new symbols fall into place, allowing cascades to continue as long as additional winning combinations appear.

The game includes nine regular paying symbols. Lower-value icons include items such as ropes and weapons, while higher-paying symbols feature character heads, skulls, and hands. Depending on symbol type and quantity, payouts range from 0.1x to 666x the player’s stake when eight to 19 or more matching symbols land. Wild symbols are also present and can substitute during win calculations.

All wins generated during a single spin feed into a Total Win Bar positioned outside the grid. Instead of paying out immediately, each cascade adds its value to this bar, which only releases the accumulated amount once the spin and all resulting cascades have finished.

The slot is classified as medium-high volatility. Stakes begin at $/€0.10 and can be set as high as $/€50. Across its available return-to-player configurations, the highest RTP version reaches 96.35%.

Wailing Wheels and Multiplier Mechanics

A defining feature of Pray for Six is the Wailing Wheels system, which activates through the appearance of special “6” symbols. A “6” activates if at least one win occurs on the grid and all cascades have completed. If these symbols fall during cascades, they arrive already activated. Only one “6” symbol may land on a reel at any given time.

Each activated “6” triggers a Wailing Wheel in its position. When spun, the wheel can award a Cash Prize, an Additive Multiplier, a Multiplicative Multiplier, or a MAX WIN that pays instantly. Cash Prizes are divided into three tiers: Bronze values range from 1x to 4x the bet, Silver from 5x to 20x, and Gold from 25x up to 666x.

Multipliers collected from Wailing Wheels accumulate beside the Total Win Bar. Additive values increase the existing multiplier total, while Multiplicative values multiply it. Additive options range from 2x to 333x, while Multiplicative options range from x2 to x33. Once all Wailing Wheels have resolved, the final Total Win Bar amount is multiplied by the combined multiplier before paying out. The bar then resets for the next spin.

Free Spins Modes and Purchase Options

Pray for Six includes three free spins bonus games, each triggered by landing a specific number of scatter symbols in the base game. Unholy Offspring activates with three scatters and awards 10 free spins, using the same mechanics as the base game but with an increased chance of landing “6” symbols. Cradle of Chaos begins with four scatters and also grants 10 free spins, while making the Total Win Bar progressive for the duration of the bonus. The Hidden Epic bonus, Playtime in Purgatory, triggers with five scatters and guarantees at least one “6” symbol on every spin.

During any free spins round, landing two additional scatters adds two extra spins, while three scatters add four more.

For players who prefer direct access to features, the game offers several purchase options. These include BonusHunt FeatureSpins at three times the bet, which increases the likelihood of triggering a bonus, a 666 FeatureSpins option at 50x the stake that guarantees at least one “6” symbol, and direct buys for Unholy Offspring and Cradle of Chaos at 100x and 300x the bet, respectively.
