3 Oaks Gaming launches 4 Wolf Drums slot

3 Oaks Gaming has added another title to its Hold and Win collection with 4 Wolf Drums: Hold and Win, a slot game set in a wild, mountainous forest.

The game is built on a 5×3 grid with 25 paylines and centers around vibrant green, blue, and red Drum Meters that fill up as matching Bonus symbols land on the reels. Once a meter is full, it triggers the main Hold and Win Bonus round, where players can chase fixed Mini, Minor, Major, and Grand Jackpots.

The visual style leans heavily into its wilderness theme, with rhythmic energy and a backdrop of dense trees and rugged peaks. The core mechanic involves collecting symbols to fill the drums above the reels, which then unleash different features during the bonus game.

How the new mirror feature works

Three exciting features make the bonus round even more thrilling. The Collect feature collects all visible symbol values on the screen, and the Multi feature drops multipliers into random empty spaces to increase the likelihood of wins. The Mirror function is a big new feature. It adds two extra rows to the grid and copies symbols into the new space. If you can fill this bigger grid, you can win the Royal Jackpot, which is worth 5,000 times your stake.

There is also a Master Drum mechanic that can trigger at any moment during the bonus. This feature releases additional Bonus or Jackpot symbols into empty cells, and can even reset your respins or reactivate features that have gone dormant, keeping the round alive for longer.

Head of Sales Krasimir Pankovski said the title “demonstrates our continued focus on crafting fresh and engaging titles that elevate the Hold and Win portfolio.”
