Blackpowder Oath Slot Demo by Rilljke

Blackpowder Oath by Rilljke Slot Overview

Blackpowder Oath by Rilljke brings a frontier town to life with dusty sunset colours, wooden buildings and rustic detailing. Its Wild multipliers share a mechanic with 5 Lions Megaways 2, but here an Oath Mark transforms an entire reel into Wilds and forges its multiplier.

Last Testament adds a distinctive collect phase, gathering Wilds and a multiplier before Showdown spins can reload after a win. High volatility adds risk, while bought bonuses have different outcomes from triggered features. Explore these mechanics in the free demo on BonusTiime, without an account or deposit.

12,500x the bet is the cap, so a €1 spin reaches €12,500 at maximum.

Blackpowder Oath Slot Features

Blackpowder Oath combines Oath Reels, three distinct bonus modes, and a high-risk Bonus Buy menu, with each feature changing how Wilds, multipliers, and spins interact.

Oath Reels

When an Oath Mark lands, its whole reel turns Wild and awards one multiplier. In the base game, the multiplier can be x2, x4, x5, x10, x20, x25, x50, x100 or x125. In Bell Tolls, it can also be x3, x6 or x15.

Bell Tolls

Bell Tolls gives exactly 10 free spins and lands Oath Marks far more often than the base game. Every Oath Reel forges its own multiplier, and every win comes from an Oath Reel. A triggered round forges 3 or 4 Oath Reels, while a bought one forges 3, with rare cases of 4 or 7, unless none are forged: about 1 in 10 triggered rounds and 1 in 11 bought rounds end this way without a win.

Powder Vault

Powder Vault gives exactly 10 free spins and drops 3 Wild coins during the feature, never more than one per spin. Each Wild coin locks in place until the feature ends. In a bought version, Oath Marks can also land and forge extra multipliers, which changes the payoff profile.

Last Testament

Last Testament starts with a collect phase and 3 lives. Each draw either collects a Wild with a higher multiplier or misfires and removes one life. Once 3 Wilds are collected, remaining draws misfire until all 3 lives are lost; the feature then moves into 3 Showdown spins, where every win is multiplied by the collected value.

Bonus Buy

This menu lets you buy features directly and jump into their bonus rounds immediately.

• Bell Tolls: x100 the bet; buys 10 free spins.
• Powder Vault: x100 the bet; buys 10 free spins.
• Last Testament: x200 the bet; buys collect phase and 3 Showdown spins.

Blackpowder Oath Slot Review

Blackpowder Oath builds its identity around a dusty Western town, sepia tones and a wooden interface that suits the frontier setting. The Oath Reels mechanic gives the artwork a clear job beyond decoration, while the outlaw symbols keep the board anchored in its saloon style.

The game turns more interesting when the bonus structure starts layering in Oath Reels, locked Wild coins and the Last Testament collect phase. That depth helps, but the high volatility comes with different feature limits: triggered Bell Tolls, Powder Vault and Last Testament cap at 45x, 40x and 120x the base bet respectively, while bought features can reach 12,500x.

Blackpowder Oath has the same theoretical RTP in base game play and bought features, so longer sessions and feature buying do not offer a higher expected return. The mechanics feel deliberate rather than messy, but the overall package still leans on multipliers and bonus variance more than fresh ideas.
