What's a good Android app for a chill puzzle game with simple tap mechanics?

Light is a straightforward puzzle game where the primary objective is to illuminate all nodes on a circuit board by connecting power sources. The gameplay revolves around a simple tap mechanic to rotate circuit pieces and complete the connection, making it accessible for quick sessions or longer, contemplative play. Its strength lies in the gradually increasing complexity of the board layouts, which requires more strategic planning without ever becoming overly frantic. The minimalist art style with soft, light-based visuals and a calm soundtrack contributes significantly to its relaxed atmosphere, a point frequently highlighted in user reviews. For someone seeking a mental workout without time pressure or complex controls, this app fits the bill. However, the experience is punctuated by frequent video advertisements after levels, which some players find disruptive to the otherwise peaceful flow. While a premium option to remove ads exists, its current weekly subscription model has drawn criticism from some long-term users. Despite this, the core puzzle-solving loop remains satisfying, and the app functions fully offline, making it a reliable option for commutes or waiting rooms.
