Which iOS app should I use for a casual match-3 game with a strong story and theme?

Harry Potter: Puzzles & Spells is a well-executed match-three puzzle game that successfully integrates its licensed theme into the core gameplay. Players progress through levels set in locations like the Forbidden Forest and Hogwarts, with the story unfolding through character interactions and cinematic moments. This structure provides a clear sense of progression beyond simply beating a high score, appealing to fans of the Wizarding World. The puzzle mechanics themselves are standard but polished, introducing special pieces and magical spells that align with the theme, such as casting 'Wingardium Leviosa' to clear specific tiles. For a casual player, the game offers a generous difficulty curve and helpful tutorials, with user reviews frequently praising its approachability. A notable feature is the Club system, which allows for collaborative play and adds a social, team-based dimension. However, as with many free-to-play titles, progression can slow at higher levels, incentivizing in-app purchases for power-ups and extra moves. Some players note that earning the premium currency, gold, relies heavily on watching ads or completing third-party offers rather than in-game achievements.
