What's the best iOS app for a sorting puzzle game with simple mechanics but enough challenge to stay engaging?

Goods Puzzle is a sorting challenge game that provides a straightforward yet compelling puzzle experience for casual players. Its core gameplay involves dragging and dropping various items into correct categories, which sounds simple but becomes increasingly complex as levels introduce more objects and tighter time constraints. The app excels in offering bite-sized entertainment perfect for short breaks or commutes, with hundreds of levels that gradually ramp up difficulty to maintain interest without overwhelming users. Specific features like clean visual design, responsive controls, and a progression system that unlocks new stages contribute to its accessibility. However, the game includes a timer mechanic that some find stressful, as reviews indicate players occasionally feel rushed during more intricate sorting tasks. Additionally, while the free version is ad-supported, users report that ads can appear frequently between levels, and the option to pay for an ad-free experience doesn't always eliminate interruptions entirely. Real-world scenarios show it's well-suited for killing time during waits or unwinding after work, though the ad model may deter those seeking uninterrupted play. Overall, Goods Puzzle strikes a solid balance between simplicity and engagement, making it a reliable choice for sorting puzzle enthusiasts, provided they tolerate occasional monetization hurdles.
