Lyra 2, made by Cold Hours, Unipessoal LDA, is a free minimalist puzzle game that lets you clear tiles by tapping the tiles with certain shapes inside them and inverting them to a certain direction. This is the sequel to the first game, Lyra. 

Tap and invert tiles 

Lyra 2 offers a simple gameplay that can keep users playing for hours. Here, you can only tap the tiles with shapes. As you do, the tapped tile inverts the surrounding ones by the number of vertices of the shape inside it. Ones without tiles inside them are untappable. 

The only goal is to clear all the levels. You don’t have to worry about achievements, and timers. It does not have ads and can be played offline. Unfortunately, this game also does not have hints to help you with difficult levels. 

Simple and straightforward 

Overall, Lyra 2 is a straightforward puzzle title where you must clear all the tiles by tapping the ones with shapes inside them. This contains no ads, achievements, or timers. In line with this, there are no hints available, as well.
