Mobile games and minimalist games have the virtue and problem that they often focus on a very simple concept, leading to a sometimes polished result. This is the case with LYNE, which is very similar to the puzzles published by the Japanese magazine Nikoli. The idea is that of a grid whose intersections present polygons or junction boxes, which can have between two and four connections: the aim is to draw lines that connect similar polygons, without it being possible to go back over a line already drawn. In addition, the junction boxes must be filled, i.e. lines must be passed through these intersections the required number of times. These rules are particularly simple and intuitive and you get into the game very quickly. The essence of the game comes from the infinite number of problems that can be designed: in the main campaign, the game offers 650 puzzles of relatively increasing difficulty, sometimes with particular themes within each puzzle collection - one for each letter of the alphabet. All of this has the merit of offering a fairly relaxing experience, never really frustrating and in a format that is perfect for being nibbled on little by little. Nevertheless, one can regret a certain lack of inventiveness at times, especially in the last sets where the same logic comes back in a loop: not that this is necessarily bad and that new mechanics should have been integrated, but one can wonder if 650 puzzles weren't a bit excessive, especially with the randomly generated daily problems. In any case, LYNE remains a decent experience, far from the usual video game hassle.
