Testament (Play'n Go) Slot Review

Testament: Slot Overview 

Unleashing chaos straight from the world of thrash metal, Testament by Play’n GO is a brutal, high-volatility online slot that dials everything up to 11. Inspired by the legendary Californian metal band of the same name, this slot doesn’t pull punches—either in its theme or in its gameplay. Released on March 12, 2020, it forms part of Play’n GO’s growing catalogue of music-themed slots, but Testament stands out as possibly their heaviest and most intense. 

With a 5×3 reel layout that can expand to a 5×4-5-6-5-4 format, and up to 2,400 ways to win, Testament merges metal mayhem with serious slot mechanics. Armed with modifiers, multiple types of free spins, a slick base game, and a max win of 20,000x your stake, this is a slot that challenges players to survive the pit while chasing gigantic rewards.

Design and Graphics 

From the first spin, it’s clear that Testament is not here to blend in—it’s here to dominate. Visually, it’s drenched in darkness and power, echoing the aesthetic of metal album covers. The background is a gothic cathedral-like setting, lit by eerie blues and purples, reminiscent of Game of Thrones’ Red Keep meets an apocalyptic music hall. The reels are framed in steel and fire, with symbols that scream heavy metal: flaming swords, vampiric warriors, werewolves, horned skulls, and the band logo font used for the card royals (10 to A). These design choices aren’t subtle—they’re metal as hell. The overall look is polished, intimidating, and fittingly aggressive. 

Even the transition to expanded reels during the bonus rounds is fluid and cinematic. Visual flair isn’t just aesthetic here—it ties directly into the gameplay narrative. Testament feels like a love letter to metal fans, but with broad enough appeal to entice all kinds of slot players.

Gameplay Mechanics 

At its core, Testament begins as a 243-ways-to-win slot on a 5×3 grid, but that expands dramatically during the free spin features. Players need to land matching symbols from left to right, starting from the leftmost reel, as is standard in ways-to-win mechanics. 

What sets Testament apart is its layered approach to features. The base game itself is fairly straightforward, but it serves as a springboard into multiple phases of escalating bonuses. This progression keeps gameplay from ever feeling stagnant, and players who unlock the features will find themselves navigating an arsenal of upgrades and wild variations. 

There are three core modifiers, each tied to one of the game’s “song features” (more on those below), and all play a role in helping players reach the ultimate goal—Testament Free Spins, where the grid expands, blockers are cleared, and multipliers mount in dramatic fashion.

Sound and Music 

You can’t have a Testament slot without the actual band—and Play’n GO doesn’t disappoint. The entire audio design is built around Testament’s “Dark Roots of Earth” album, which serves as the pounding, headbanging soundtrack to the gameplay. Guitars shred, drums thunder, and riffs blast with every win and transition. 

If you’re a metal fan, this will be a dream come true—a relentless audio experience that actually enhances the tension and drama of the slot. If you’re not into metal? Well, you might want to hit mute, because this soundtrack doesn’t let up. 

Voiceovers and sound effects are also well-produced. Every spin, every win, every feature is punctuated with clanging chains, howling winds, and dark choral tones. It’s immersive, aggressive, and incredibly well synced to the game’s pacing.

Bonus Features 

This is where Testament truly flexes its muscles. The slot is packed with features that escalate as you progress: Song Features

Triggered by landing 2 scatter symbols, these mini-bonus rounds grant 3 free spins with one of the following active: 

Dark Roots of Earth: Wilds expand up and down the reels. 

Cold Embrace: Wilds lock in place until the end of free spins. 

Throne of Thorns: Expands the grid to a 5×4-5-6-5-4 format, increasing win ways to 2,400. 

These Song Features serve as a preview of the chaos to come—and can seriously boost your balance even before the main bonus begins. 

Rise Up Free Spins

Land 3 scatter symbols to trigger 9 Rise Up Free Spins, which begin with the full expanded grid but covered in blockers. Each scatter symbol that lands during the round destroys a blocker and increases your ways to win. 

Remove all 9 blockers, and the real beast awakens… 

Testament Free Spins

Clear all blockers in Rise Up Free Spins to unlock Testament Free Spins. Here, things get wild: 

All three Song Features activate simultaneously 

3 extra spins are awarded 

Wilds lock, expand, and spread 

The expanded grid remains active with 2,400 ways to win 

This is the ultimate showdown. Get here, and you’re in the mosh pit of slot bonuses, with everything turned up to max.

Betting Options and Payouts 

Testament caters to a broad range of players, offering bets from €0.10 to €100 per spin. The RTP is 96.20%, though operators may offer lower RTP versions, so it’s worth checking before you play. 

Here’s how the payouts break down: 

Card royals (10–A): Low pays, stylized in band fonts 

Swords, throne warriors, werewolves, vampires, skulls: High-paying symbols 

The horned skull is the most valuable, paying 12.5x for 5 of a kind 

Wild symbol pays 15x and substitutes for all except the scatter 

Scatter (album cover) is key to unlocking features 

The max win is a whopping 20,000x, putting this slot in elite territory. However, don’t expect it to land easily—it’s called high volatility for a reason.

Conclusion 

Testament is Play’n GO at their boldest and most unapologetic. It’s a hard-hitting, feature-packed, metal-themed masterpiece that doesn’t care if it’s too loud—it wants to be felt as much as played. The slot pushes boundaries with its complex multi-stage bonus structure, escalating modifiers, and insane 20,000x potential, while the heavy metal soundtrack and dark visuals tie it all together into one aggressive, unified experience. 

This isn’t a slot for light casual players or those looking for serene spins—it’s for fans of volatility, high-stakes action, and adrenaline-fueled bonus rounds. And if you happen to be a fan of the band Testament? That’s just the headbanging cherry on top. 

Verdict: Brutal, brilliant, and beautifully built. Testament is one of Play’n GO’s loudest triumphs yet.
