GameArt’s Joan of Arc slot machine, even with its five reels and multiple win lines, has a pretty slow-paced gameplay where wins don't happen often. The main excitement comes from the bonus rounds, which add some thrill to an otherwise dull experience. Players can choose to use a gamble feature, which adds more risk and some variety to the game. Although its medium volatility supports different betting strategies, the game's unwillingness to reveal its Return to Player (RTP) rate is concerning, making many people wary of its lack of transparency.

The game's visual appeal is undeniable, taking players to a medieval battlefield with its well-crafted artwork and animations. The game's symbols, enhanced with chainmail backgrounds, create an immersive and visually stimulating experience. The soundtrack, matching the historical theme, is spot-on—engaging but not overwhelming with repetitive loops. This perfect mix of sound and imagery sets an evocative tone suitable for the story of Joan of Arc.

Speaking of the theme, GameArt draws on the legend of Joan of Arc, made famous in Leonard Cohen's poignant lyrics. The brave heroine, known for her military skills during the Hundred Years War, now plays a different role in the game’s narrative—offering chances for big wins. Landing the Joan of Arc symbol promises the highest rewards, giving players something significant to aim for in the medieval setting.

In conclusion, despite the stunning visuals and appealing theme, the Joan of Arc slot machine falls short due to two main issues. The lack of essential statistics like RTP and the game's average volatility creates uncertainty and distrust. Additionally, the basic features and uninspired gameplay fail to hold long-term interest, overshadowing the impressive graphical execution. These factors lead to a recommendation against investing time or money in this game, as the cons outweigh its potential pros.
