There are a great many games in the virtual space, and among them there are so-called contradictory ones. They seem to be elementary with a simple interface, but in fact, when you start playing, it turns out to be not so simple. Arrow is an example of such a game. The task is nowhere simpler - shoot with hairpins into a rotating circle, but at the same time you cannot get into an already stuck needle, and this already creates problems. Further more - the circle begins to rotate in one direction, then in the other, or even does not make full revolutions at all, but turns as he pleases. At each new level, the number of pins is added, which you must stick into a round object in the Arrow.
