One of the most popular puzzles in the world is Chinese Mahjong. In the game, you will need to puzzle out the bones for a particular time, on which certain drawings will be applied. But you have to do it for a certain time, as said above! Having found two identical bones, you need to select them with a mouse click and they will disappear from the screen. At the same time, remember that after some time the bones are able to change their location in space and shuffle among themselves. In order to easily cope with tasks, use your logical thinking, attention, and ingenuity. During the game, you develop your attention, and this allows you to escape from all problems and focus on a specific task.
