If you want to spend your time interestingly and usefully, and at the same time test your powers of observation and reaction speed, then the new online game Dots & Cross is for you. A green cube of a certain size will be visible on the screen in front of you. A black circle will appear in it, which will increase in size. You will have to very quickly click on the center of the circle with your mouse. By doing this you will receive points in the Dots & Cross game. If a cross appears, you should not touch it. If you touch the cross, you will lose the round.
