The monochrome logical world of figures invites you to play Lozy. Figured inhabitants noticed strangers in their ranks. Outwardly, they almost do not stand out from the main mass, but the Aborigines know best who is their own and who is a stranger. They ask you to expel the aliens. You do not have to look for them, all those who are ready to leave the space will face you. The problem is that they are not going to leave, and they can be destroyed only by a small black ball, which you must set to the chosen position. The ball is only one, and the figures can be many, the location depends on the success of the operation. If it did not work the first time, repeat.
