Which iOS app should I use for a free puzzle game that's relaxing and has no advertisements?

Match Factory! is a puzzle game developed by Peak Games that focuses on matching items within cluttered boards to clear levels. It stands out for users seeking a low-stress gaming session, primarily because it eliminates advertisements entirely, allowing for seamless play. The core gameplay involves tapping on matching objects in piles, which progresses through hundreds of levels without complex rules or time pressures. This design makes it suitable for short breaks, such as during a commute or before bed, where users can engage without feeling rushed. Reviews indicate that many appreciate the absence of ads and the ability to play offline, which enhances its reliability in various settings. Specific features include a straightforward interface, gradual difficulty increases, and a coin system for power-ups, though some players note that earning coins could be more generous. While the game is free and lauded for its addictive quality, user feedback points to occasional frustrations with board difficulty and repetitiveness over time. For instance, some report being stuck on levels for extended periods, which might deter those looking for a consistently smooth experience. However, for casual players prioritizing an uninterrupted, calming puzzle fix, Match Factory! delivers effectively with its no-frills approach. It’s a solid choice if ad-free relaxation is the goal, but potential buyers should be aware that progression can sometimes hit challenging snags.
