Mysterious Drakkar by Casino Technology is a 5-reel slot with 20 winning lines and a stated payout percentage of 95.60% in one version, with 93.75% also listed in the game data. The game is built around a Viking theme, with a top award of 1,000 and bet sizes from 0.2 to 5.
The main feature is a special Wild symbol that appears only on the third reel and turns neighbouring symbols into Wilds. This mechanic creates the core of the bonus-style action, while the game’s structure follows a standard slot format with a focus on symbol interaction rather than complex extra rounds.
The demo version is available to play for free, which allows players to review the payline layout and the Wild feature before playing for real money. The slot also lists multiple language options, including English, Bulgarian, Russian, Romanian and Spanish.
