Sword of Arthur
Thunderkick presents a mythical and heroic adventure in this five-reel slot release. The base gameplay takes place across a traditional grid equipped with ten active winning lines. Players aim to trigger the main bonus round, which grants extra spins containing special expanding icons. Throughout these extra rounds, an increasing multiplier works to improve payout potential, while a unique reset mechanic adds another layer to the action.
