One of the most popular categories of relaxing computer games is to match at least three identical objects to remove them from the board. The free project Lills successfully represents this trend. We are dealing with a colourful, joyful and well-sounding work, which will surely appeal to younger PC users as well. The title has a fictional background. We get to know the land of elven-like creatures. Their princess was kidnapped by an evil witch and the players' task will be to liberate her. On the right hand side of the screen there is a violet witch's power indicator that grows every second. In order to counteract it, move objects in such a way that they are grouped in several places of the same size. After being eliminated, they will give magical pollen, allowing them to defeat their opponent. The whole story has been divided into many multi-level chapters, with a constantly changing graphic background and objects in the layout, so there is nothing to complain about monotony. The game runs slowly, making the title a good introduction to the genre for children. In addition to attractive graphics, with illustrations of quite juicy colors, time is effectively enhanced by background music, as if taken straight from the fairy tale.
