Introduction to Raidmark
Raidmark is a casino slot from Ace Roll that lets us join in on the biggest Viking raid of the century. The studio Ace Roll is a newcomer to the scene, being partnered with Hacksaw Gaming’s OpenRGS and debuting in 2025. Previously, we’ve checked out their release, Mirage City, an EDM-themed slot game with tons of Multipliers, Respins, and Free Spins. Comparing that to Raidmark, and we’re in a completely different Millennium, being themed around Vikings. Gameplay-wise, Raidmark is a bit simpler in tone, being largely centered around its different Expanding Wilds with Multipliers that range up to 200X. Ace Roll has then taken inspiration from Hacksaw Gaming, introducing two different Free Spins bonus games which can keep the Expanding Wilds around for just a few more spins, helping you stack up wins and maybe reach the max win of 10,000X the bet.
Join the warship as we travel to new, fruitful lands, ripe for pillaging, alongside your fellow Viking Multiplier Wild Symbols. If you want to try the game for yourself, be sure to give the Raidmark demo a try.
Theme, Gameplay, & Payouts
Raidmark is a video slot from Ace Roll with 5 Reels, 4 Rows, and 14 Paylines. You can choose between making a Min.bet of 0.1 and a Max.bet of 100. Raidmark comes with a slightly higher-than-average RTP of 96.27%, high volatility, and a solid max win of 10,000X the bet.
In the base game, we find ourselves on a march in foreign lands, aiming for the kingdom on the horizon. Later in the bonus games, pillaging begins, first with the local village, and later, we find ourselves in the throne room, filled with chests of gold. You can play the game on most desktops, notepads, and mobiles.
The lower-paying symbols are 10, J, Q, K, and A. Creating a win with 5 of the same symbols will pay out 0.5X to 1X the bet. The higher-paying symbols are various weapons and armor, including axes, a hammer, a shield, a helmet, and a horn. Landing a win with 5 of the same symbols pays out 1.5X to 5X the bet. Then we have the two standard Special Symbols, namely the Expanding Wilds with Multipliers and Free Spins Scatter Symbols, but more on them in the next section.
Special Features & Mechanics
What is the max win in the slot Raidmark?
You can win up to 10,000X the bet.
What features are available in the slot Raidmark?
The features are Expanding Wilds, Onward Bonus Game, The Mark of Raid Bonus Game, and Feature Buy.
Expanding Wilds
Wild Symbols appear as 3 types of Vikings and substitute for all symbols except Scatter Symbols to help create winning combinations. Whenever a Wild Symbol is part of a winning combination, it will expand, revealing a Multiplier value, which depends on which Viking appeared. The Vikings are as follows:
Rookie Viking = Can appear with Multipliers ranging from 2X to 10X.
Raider Viking = Can appear with Multipliers ranging from 15X to 50X.
Veteran Viking = Can appear with Multipliers ranging from 100X to 200X.
Onward Bonus Game
By landing 3 Scatter Symbols, you will be awarded the Onward Bonus Game with 10 spins, plus an additional random amount ranging from 1 to 12, determined by a dice roll. This bonus game keeps all features from the base game.
The Mark of Raid Bonus Game
By landing 4 Scatter Symbols, you will be awarded the Mark of Raid Bonus Game with 10 spins, plus an additional random amount ranging from 1 to 12, determined by a dice roll. During the bonus game, each time a Wild Symbol lands, it will always expand, and after each spin, a random outcome determines whether each Expanded Wild Symbol remains on the grid or disappears for the next spin.
Feature Buy
Through the Feature Buy option, you can trigger various features and bonuses for a price based on the current bet.
3X = Triggers the BonusHunt FeatureSpins, making each spin 5 times more likely to trigger a bonus game.
50X = Triggers the Disembark FeatureSpins, guaranteeing 2 Expanding Wild Symbols drop. But, no Scatter Symbols can land during the spin.
100X = Awards the Onward Bonus Game.
200X = Awards the Mark of Raid Bonus Game.
Final Thoughts on Raidmark
Raidmark completely switches the tone from Ace Roll’s previous releases, now instead coming with a darker and more gritty tone. We always enjoy some raiding and pillaging in our slots, and Raidmark leans into its Viking theme well, with a nice soundtrack and character-based Wild Symbols, which are also the main core feature of the game. It feels like the studio is still only testing the waters with graphics, animations, and visual style, which makes Raidmark maybe not look as good as it could and, even sometimes, feel a bit dated.
Outdated games can still be relevant if only their gameplay can catch an audience, and while we, and most players, love Expanding Wilds with Multipliers, it seems like Ace Roll is a bit too dependent on them. Any spin that they land on and trigger always feels great, as the paytable isn’t the best, so having additional Multipliers, especially those big 200X ones, is more than welcome. While there are two types of Free Spins, one of them doesn’t bring any new bonuses, and is literally only free spins, while the second one only has a chance to keep Expanded Wilds around for one additional spin. We expected something a bit more, maybe Sticky Wilds, or maybe something like a Total Win Multiplier, since the gameplay loop boils down to spinning for Wilds, which isn’t very fun in longer play sessions, as everything becomes a bit too repetitive.
Raidmark is a Viking-themed slot all about its Expanded Multiplier Symbols, as the rest of the game’s bonus games are a bit too shallow to really impact the spins in a meaningful way.
