Fight the virus. Its Corona is constantly growing, it is necessary to rotate the core and find chains of thorns of the same color and destroy them. Chains can be searched in adjacent cells in all directions. Each step limited in time, take your time until the virus has collected the entire Corona.
Every stage hands you a small, self-contained problem with a clean answer somewhere inside it. Matching three, sliding blocks, connecting pipes, rotating tiles; the mechanics change but the feeling is constant. You test an idea, watch it fail, adjust. Later stages layer two or three rules together so the obvious move is usually the wrong one. It is quiet, methodical play.
Short, finishable chunks. A stage of Corona Lines takes a couple of minutes, which makes it a good match for a wait at the bus stop or the last five minutes of a lunch break. It loads in a tab without an install, so there is nothing to clean up afterwards.
Suits adults who want a calm break and children old enough to read simple instructions. Casual players will find the early stages gentle, and anyone who enjoys sudoku or crosswords should feel at home.
