Spinomenal offers its own vision of the apocalypse through the 4 Horsemen slot machine. Launched in 2019, this creation was so successful with players that it spawned several sequels, including a version incorporating the Hold & Hit mechanic.
The 4 Horsemen game features an unusual 3-4-4-4-3 grid with 30 paylines. Its medium volatility and 94.5% RTP offer a moderate level of risk. The maximum win per spin is achieved by landing 5 Wild symbols on a single line, awarding 150x the bet per line.
Notable features include the Mega Symbols mechanic, where knight symbols can occupy 2×2 or 3×3 blocks, and stacked Wilds appearing on the outer reels in the base game. Players can also enjoy free spins, a Prize Box containing surprises, and a special bonus offering instant rewards.
Theme and gameplay
Everything is in ruins; not a soul remains, not a light—only ashes and darkness. The 4 Horsemen slot machine draws inspiration from the apocalyptic imagery of the Four Horsemen of the Apocalypse. The graphic atmosphere relies on dark and menacing hues, fully emphasizing the theme of the end of the world.
The interface is visually rich in effects: symbols evolve against an animated background of flames and ruins. The soundtrack is tense and immersive, punctuated by powerful percussion and unsettling sounds.
The graphics in 4 Horsemen are of near-movie trailer quality. The controls are clearly indicated, and key features can be explored through specific animated previews.

- Bonus Game: Bonus symbols appear randomly and offer an immediate win. They are exclusive to the base game.
- Free Spins: If the Free Spin symbol appears simultaneously on the first and fifth reels, this triggers 10 free spins.
- Prize Box Feature: During free spins, a special function is activated: with each spin, the Prize Box located in the top right awards either a winning multiplier or additional spins.
RTP and Volatility
The RTP (Return to Player) of the 4 Horsemen slot machine is 94.5%, which indicates the average percentage of bets paid out to players over the long term. In practical terms, this means that theoretically, for every €100 wagered, approximately €94.50 is paid out as winnings, while €5.50 remains with the casino. Given its medium volatility, wins occur fairly frequently and generally vary depending on the amount wagered.
Conclusion
The 4 Horsemen slot machine is a dark yet spectacular game with an unconventional structure. Its relatively modest RTP is more than compensated for by an original design blending horror and fantasy elements, as well as numerous unique mechanics. Free spins are enhanced with random prizes, while the base game allows you to land stacked Wilds and instant bonuses.
